My Dad's Internet Radio Boot Loops After Lightning Strike to Router???
Summary
TLDRThe video shows the repair of an expensive John Lewis internet radio that was malfunctioning after a lightning strike. The radio would boot loop and make a high-pitched noise. After some troubleshooting, the issue appeared to be faulty output capacitors in the power supply. Replacing them seems to have fixed the boot looping problem, though the cause of the noise remains a mystery. Overall, it provides a good lesson in debugging intermittent electronic faults and the importance of those small capacitors.
Takeaways
- 📰 The video focuses on troubleshooting a John Lewis Internet radio that experienced issues following a lightning strike, highlighting the resilience and challenges of repairing modern electronics.
- 🔧 Initial repair years ago was simple, involving soldering a loose joint, demonstrating that some electronic issues can be resolved with basic fixes.
- 🚨 Post-lightning, the radio experienced boot looping and connectivity issues, suggesting that surges can cause complex problems in electronic devices.
- 📱 The use of Wi-Fi over Ethernet as a workaround for network issues showcases flexibility in solving connectivity problems but also introduces new variables in troubleshooting.
- 💻 Exploration of potential causes, including capacitor failure and impact of lightning through indirect means (e.g., scaffolding, telephone wires), illustrates the detective work involved in electronics repair.
- 🔋 Testing with a bench power supply and investigating capacitor health underscore the importance of methodical testing in diagnosing electronic device issues.
- 🛠 Replacement of suspected faulty capacitors with ones of incorrect voltage rating but correct capacitance highlights the role of experimentation in repairs.
- 🔌 Discovery that the radio works at lower voltage thresholds suggests that certain problems can be mitigated or bypassed through unconventional methods.
- 📲 The persistent hum detected during CD playback and its absence in other modes points to specific component issues, possibly related to grounding or interference.
- 🔢 The final resolution remains inconclusive, with the repair being effective yet not fully understood, reflecting the often uncertain nature of diagnosing and fixing electronic problems.
- 📺 The video concludes with the radio functioning correctly after capacitor replacement, though the exact cause of the original problem (boot looping) and the hum remains somewhat speculative.
Q & A
What device is being repaired in the video?
-An internet radio made by John Lewis.
What was the initial fault with the radio?
-There was an issue with a solder joint where the mains power enters, which was fixed in a previous repair. More recently, it had issues connecting via WiFi which was also fixed.
What happened after a lightning storm that caused new issues?
-After a lightning storm, the radio started boot looping - turning on and off repeatedly. This happened after the storm caused issues with the internet connection.
What voltage does the radio's power supply output?
-The radio runs on 15V DC from its internal switch mode power supply.
What components were initially suspected as the fault?
-The output capacitors on the power supply were initially suspected, as they can often fail over time.
Were the original output capacitors actually faulty?
-No, when tested the original output capacitors measured as working correctly. However, replacing them seemed to fix the boot looping issue.
What other fault does the radio have?
-There is a high-pitched whining noise, specifically when playing CDs. The source of this could not be found.
How was temperature related to the boot looping fault?
-When cooled right down, the radio would start boot looping again. This pointed to an issue related to temperature or components getting warm.
How long did the repair last before further issues?
-Over a week later, after extensive use by the video creator's father, the radio was still working normally with no further boot looping.
What components will be replaced going forwards?
-The temporary lower voltage output capacitors will be replaced by correct higher voltage Panasonic capacitors.
Outlines
😐 Introduction of the video and describing the internet radio that will be repaired
The video introduces an internet radio made by John Lewis that was expensive but has been having issues. The radio connects via ethernet or WiFi to allow streaming audio. It had a previous issue that was repaired by soldering a joint. Recently there was a storm which seems to have caused a new problem with the radio boot looping and not working properly.
🔌 Removing and testing the power supply
The power supply is removed from the main board to test the output capacitors. The capacitors test ok for capacitance and ESR. 6 volts can turn the radio on but it doesn't fully work. New lower voltage capacitors are installed since the required ones are not available.
😕 Reassembling and troubleshooting issues
After reassembling, the radio has a high pitched noise, especially on the CD input. The radio continues having odd intermittent issues. The voltage is measured at 15V. Various debugging is done but the source of the noise cannot be found.
🤔 Considering potential causes
With no obvious cause found, potential theories are discussed. A lightning strike may have caused the issue but it is unclear how. The capacitors that were replaced test ok. The noise and problems seem to be temperature related somehow.
✅ Testing in the cold
To test if temperature is the cause, the radio is left outside in the cold. When brought back inside, it starts up normally with no looping. Interestingly, the noise is also now gone. After extended testing, the radio seems to be working reliably.
😊 Conclusion and future repairs
In conclusion, the radio appears to be repaired for now by replacing the capacitors. The cause of the noise issue is still unclear. Output capacitors going bad is a common issue that applies to many devices, so this repair experience will help with future repairs.
🎉 Success and proper capacitors installed
As a follow up, after over a week of use by the owner, the radio continues working well with no issues. The proper higher voltage capacitors have now been installed to make the repair more robust.

Highlights
The radio was expensive but now secondhand faulty units sell for £80 and working ones sell for over £300 on eBay
The radio stopped working after a lightning strike fried the router and changed the WiFi password
The radio now boot loops, coming on with the display but turning off repeatedly after 5-6 times
The radio now makes an odd noise, possibly related to capacitors or the power supply since it works then stops
Replacing suspected faulty capacitors with new ones fixed the boot looping problem
The radio has a high pitched 3 kHz hum only when playing CDs, not with other sources
The hum seems to be temperature related - it went away when unit was very cold
Can't determine cause of hum, readers with more expertise may be able to diagnose issue
Replaced capacitors had proper capacitance but were lower voltage rating of 16V instead of 25V
Running radio off bench power supply showed it works down to 6V input voltage
The radio runs on 15V DC internally, despite being powered from mains AC
Faulty capacitors can cause problems in many devices with switch mode power supplies
Output capacitors going bad is a common fault in devices with internal power supplies
Replacing output capacitors seems to have fixed this radio
Proper 25V capacitors will still be installed though 16V ones work for now

hello there my mavin here and in this
video today we're going to be looking at
this internet radio here so this is John
Lewis radio cello was quite expensive at
the time funny enough I looked into
buying a secondhand one because this
one's playing up for my dad and a faulty
one is 80 something pound a working one
is over 300 on eBay at the moment
absolutely crazy so
I fixed this years ago in a video and it
was a nice simple one there was just a
solder joint on one of the on where the
mains comes in I think it was just past
a fuse or something that wasn't soldered
properly at the factory and all I had to
do was put a dot of solder on and then
it was all working fine and it has been
working fine the network side of it
played up cuz it normally plugs in Via
an ethernet cable but then I just went
over to Wi-Fi for him so my dad's like
really bad at technology and simp simple
things like if he mck up the preset on
this then he'll be lost but he loves it
because he can listen to things like
midr radio which is like an Irish radio
station even though he lives in London
so it suits him he listens to it every
single night I would say that this is
the most thing that he would use
technology wise so basically it's been
working fine on Wi-Fi until there was a
storm and basically the whole street was
talking about it the houses actually
shook there was a lightning St
and since then my dad's internet went
and I thought okay well sometimes his
internet does go but it turns out the
router was fried I got the internet work
again I had to buy a new router and then
I had to change the Wi-Fi passwords over
on everything and on this I went to
change the Wi-Fi password and it kept
boot looping so it would come up with
John Lewis and then it would uh when I
was going through it it would then just
go off and then it would come up with
John Lewis again and then it would go
off and it would do this about five or
six times and then it would die
completely until I turn it off at the
back and put it on again so I brought it
home annoyingly it's working but it
wasn't working first of all I plugged it
in and then it did the same thing again
I'm wondering is it capacitor related
because it's making a funny noise and
also this is another victim of the
lightning strike wherever that here now
the next door does have scaffolding up
and my dad's overhead telephone wire
because the Broadband comes through the
telephone was resting on that that
scaffolding I'm wondering whether the
scaffolding a big metal structure going
up to the roof height I'm wondering
whether that was where the lightning hit
and because my dad's wire was resting on
that although the wires are insulated
they're only going to be insulated up to
a certain amount and maybe if you got
hundreds of thousands of volts maybe
that's enough to break through the
insulation and run down there there you
go it's just gone off there you go you
see I didn't do anything and it's just
gone off there so obviously it's still
not right and annoyingly it was still
plugged in with the ethernet cable even
though it was working on Wi-Fi so
because the router went I think the
surge went through the router through
the ethernet cable into this here now
it's going to be a hard one to fix
because when I turn it on a lot of the
time it does work but it is making this
weird noise you can see now it's gone
off again so it's making this weird can
I hear it now no I can't hear it now but
when it was working it's making like
a sort of
noise right this is it back working
again but look listen to this
noise I'm going to put this microphone
right up to the
speaker now maybe that's always been
there but I'm thinking maybe that's part
of the problem okay so I'm
unplugged from the
mains now I seem to remember that it was
quite challenging to get into I think
but you know it's been a while now so I
can't actually remember if I have to
take the front off or
not I can see a load of screws around
the backs let's undo them I'm thinking
now that if there was a surge it's going
to be going via here but yet it works
you think that would knock out some kind
of like ethernet type chip on the inside
I'm wondering if now if this is just
coincidence and because it's been used
so much I'm wondering if it's the output
capacitors on the power supply cuz this
has an internal power
supply and maybe they're not stable
enough and that's why it's working and
then it stops working and perhaps it
worked more at my house than my dad's
cuz the house is warmer and maybe if the
capacitors are warmer they're going to
work
better so I just want to be wary the
fact that blaming everything on the uh
lightning
strike if it could be just complete
coincidence oo yes that was easier than
I remember okay okay now the hot glue
was that the work of me probably so this
is the little power supply here so
where's the oh and this is the output
here that goes into
here not going to be able to measure if
that's stable or not am
I there a couple of little capacitors
just here you can't see them but just uh
I want to be careful what I'm touching
because there still might be power in
here I don't think there will be but so
you see these two capacitors here I'm
wondering if I change those out because
I've got a feeling they're going to be
the output ones right let's carefully I
don't really want to get involved in
here let's carefully take out this power
supply so this is going to be the mains
coming in from uh from here to
here so that's there let's undo that
screw let's undo this secondary
connector so that's the low voltage
going out I think
let's undo these screws
here I'm being careful not to touch
anything because there might be voltage
this is a 400 volt cap here so there
might be voltage left in
this okay let's put this down safely
now let's just see if we got any voltage
in that big capacitor just
here so on
DC well yeah I've got 34 volts in it
still haven't I right let's uh let's
drain that so I've got these resistors
in here so this is going to turn the
voltage there just didn't it's only 30
volts anyway but it's going to turn it
into heat that's probably going to be
enough there we
go climbing right
okay safe so I am thinking that maybe it
could be something to do with these that
they're just not
stable there's 680 microphon are 25 Vols
how have I got them 680 that's a bit of
a weird one is oh here's 680 I've got
them but only 16
Vols ah these are 25 that's annoying let
me see if I've got them in another
pack no these are 470 and 1,000 let's
have a look at the actual voltage coming
out maybe I can put in a lower voltage
in this instance
here right it doesn't say here what
voltage is coming out
so the thought before was I think one of
these solder blobs here wasn't soldered
properly I think that's that's what the
fault was at the
fuse let's see if there's any indication
on here about what voltage is going into
it I can't see anything labeled up here
but there is two massive capacitors here
as well underneath all these cables and
they're labeled up two
2,200 microfi 25
oh that's
annoying see it might not be that at all
I mean I Wonder Could It Be where it's
going into here they seem very big
capacitors there don't they see this has
had a lot of use as in it' be on for
hours each night and I don't know when I
did the video but I think I gave this to
my dad before
lockdown I tell you what I'm going to do
I'm going to unsolder them and I'm going
to check them for ESR and also
capacitance
I'm just waiting for my desolder station
to get up to uh temperature I'm just
wondering I don't really know what
voltage this runs off do I so you know I
don't know is it going to be 25 volts
here or could it be as low as like 6
Vols or 12 volts or something so why
don't I get my bench power supply and
just put voltage directly into here
remember this is what's connecting up
here for the the mains but that's out of
it now so if I was just to put for
example 12 Vols into here we could see
if it's going to start working so I
start really low on 3 volts and it's not
drawing anything from the bench power
supply it's not even attempting to turn
on I go up to 5 volts and it does draw
on the bench power supply but nothing
comes up apart from a backlight on the
screen then I put it up to six volts and
it does actually go to John Lewis on the
screen that comes up but it doesn't go
any further than that so it looks like
it's partially working as low as 6 volts
if if we put 16vt capacitors in it might
well be working maybe the inside of the
this is going to be working on 12 volts
but we will discover the voltage it's
working on later on in the video hence
the reason I'm whizzing through this bit
now there we go welcome to John Lewis
and that's just at 6 volts I wonder
would I get away then it's gone off I
[Music]
think I wonder would I get away with
those
capacitors well there's only one way to
find out Vince and that's to pop the new
ones in so I desolder unsolder the
faulty capacitors and then I the
suspected 40 capacitors I should say and
then I pop in the correct capacitance
capacitors but the wrong voltage ratings
so there're 16 volts instead of 25 volts
I don't think anything too catastrophic
is going to happen it'd be different if
there were like 400 volt and I'm putting
in 16 Vol but 25v and 16vt I don't know
what this is going to be running at I
will will show you later in the video
what it's running at but at this moment
in time in the video I don't know what
it's running at so uh yeah that's what
I'm doing here now and let's test the
suspected 40 capacitors to see what
their capacitance is and also what their
ESR rating is things first let's just go
to capacitance on the
meter right so this one should
be 220
microfarad yeah it's pretty much is 208
I think that's all
right you never know they might have ESR
bad ESR on them this one should be
680 hope it's
out oh no 691 that's okay I don't think
it is
these no 696 well unless the ESR is out
I think they're just fine right what
should it be 680 25 Vol 680 well I
haven't got 68 I've got 470 and a th000
so 470 is 0.12 and 1,000 is 0.08 so
should we just take the middle off that
and call it round about
0.10 as the worst case
scenario no it's well under isn't it
it's well
under let's try this
one
oh yes hold on is that my dodgy leads
one second are they shoren together bear
with me it could be shorten
together get my hopes
up oh no it's just my my things were
shorten
together no that's all right do you know
what now looking back at that with the
benefit of editing I can see a different
view I see the view that you're seeing
which is straight down from the camera
remember I'm sat looking at a slight
angle I don't think my leads were short
in there looking back I'm going to show
you in just a second they both seem to
be separate from each other and I don't
think they're touching the actual can of
the capacitor so I'm wondering if this
capacitor here is slightly dodgy because
it was reading like 3 ohms or something
which is going to be well over but then
when I started wiggling things it went
down so I'm wondering if now this
capacitor could possibly be a bit iffy
let me show you again let's try this
one oh yes hold on is that my dodgy
leads one second are they shoren
together bear with me it could be
shorten
together get my hopes
up oh no it's just my my things were
shorten
together no that's all right well I'm
not so sure I mean I think the leads
were separate but it's just that the
reading was all over the place unless my
meter was just not settling it's just a
bit odd that it did seem to be over a
couple of HS so for me I'm still not
100% sure about that capacitor anyway
Let's test the last one 220 25 Vol so
this should be. 23 worse
case. 23 not. 23
no I think all those caps are okay right
I
mean it went faulty after the lightning
strike but I just can't see
how what if it was via the ethernet C
that's the only
way because if it was power surely it
would have take taken out loads of other
things in the house I mean this is
always plugged in but it's turned off at
the back well that's the answer if it's
turned off at the back a surge can't get
past a switch can it unless it was a
huge Surge and if it was a huge surge
wouldn't have blown it would have blown
the fuse would it not so unfortunately
everything kind of looks okay with this
it looks immaculate on the inside
there's no signs of water damage or
anything like that it looks brand new
but it has got a hum so let's put it
back together and carefully without
getting electrocuted see if we can
pinpoint where the hums coming from I
can use a plastic pital and maybe touch
different chips or capacitors and see
maybe there's something vibrating and by
touching that it may get rid of the hum
from the
speakers right I'll plug it in here
first and I'm going to turn it
on so unless those new caps go bang I
think think I'm going to be okay
obviously I can't touch anything here
otherwise I will be
electrocuted right let's plug it
in right it's coming live at the front
here I can see the uh the drn L thing
here so I'm going to get some internet
radio on and then start listening to it
for a while and then we might be able to
hear where the hum's coming
from
you know it's not picking up the Wi-Fi
from the from the other room but yeah I
can hear that noise but I don't know if
that noise was always there or
not I don't want to reach in here and
unplug the speakers to verify which
one's are making a
noise thing is it hasn't turned off yet
right Network time out leave it with me
for a bit I need to connected up to my
router in here and then uh I need to
just listen to to the music for a bit
and see what happens right interesting
cuz I don't actually think I'm going to
be able to fix it in this video it might
be a revisit video I've gone onto the
network wizard and when it started
scanning for the ssids as soon as it
went onto the scan the high pitch noise
has
stopped so maybe it really does have
some sort of faulty Network side of it
which is somehow drawing to much power
and causing the actual unit to boot loop
H anyway I'm going to connect it up and
see what happens so we leave we par
right it's only a minute later and I've
got Midwest radio working in here
Sherlock and he says Happy New Year to
you from SLO and all at the radio
station thanks for all the still seems
so weird reminds me of being a kid on
holiday right let's see if the noise is
there no that noise has gone what's that
about let me just go on to CD it was
just to say take Lo of Po and a
in po ah nois is back when I'm on
CD what is what does that
mean let me see if it's on anything else
Bluetooth no stop
there let's go to
Oren no no noise
there but earlier on I didn't on CD did
I FM
radio no nothing
there so maybe that's got nothing to do
with the uh the
problem it's just scanning for da
now it hasn't cut out yet though but I
have got the back off it so maybe
there's less heat being generated or
unless it's yeah unless it is an
overheating thing or is it just warmer
because I've
you know added the heat from the soldier
nine and stuff into the
board
only no squeal
there music player no squeal there
internet
radio and no squeal there popular so
it's only CD that's squealing now they
play all over yeah squeals there on
CD
interesting okay right leave it with me
for a bit I'm just going to listen to a
bit of Midwest radio
memory see I think what I'll probably do
actually is to make it safer I'm going
to put a couple of screws in here right
it's been about 10 minutes and I'm just
playing some Daniel odonnell of course
goes with the Midwest radio and uh I've
got here an app called let me just get
the name of the app
spectroid and the weird thing is that
when I'm talking you can see it's going
up and down here like you know if I'm
clapping you can see it's uh when I'm
talking it's around this thing here but
when I put it up to here and don't
speak you can see it's always up here
at it says
3,101
Hertz
but the electricity is going to be 50 HZ
isn't
it so if it was some sort of ground hum
wouldn't it be lower than
that and I think it's slightly higher on
the right speaker than the left speaker
so this is the left
speaker it's very steady isn't it now
let's go to the right
speaker
so I'm going to Google what that
actually means there and uh maybe it's a
common
thing this is really strange so
basically it's been on now for it must
have been at least 45 minutes I listened
to quite a few songs by Amy win housee
and I went back onto the internet radio
and it hasn't dropped out once I Googled
let me just lower this out I googled
this uh Hertz here so 3,000 Hertz or 3
khz and basically yes there are people
complaining of those hums on various
different things like guitar ramps and
radio equipment and other hi high-fi
equipment but there doesn't seem to be
an answer such as yes it's the diodes or
yes it's this or it's a ground hum it
just seems to be a hard one to trace so
I think I'm going to have to leave that
up to my subscribers remember I have had
this apart before so maybe I haven't put
some shielding back to where it should
be now interestingly the whole time it
was on CD it was making that noise and
then as soon as I went on to the
internet radio it stopped and now there
is no noise whatsoever but if I went
back onto CD it always comes back so if
I go to Source here and if I go back to
CD instantly it will come back there I
can hear it straight away but sometimes
when I go back to source and I go back
to Internet radio it will still be there
there you go it stopped but other times
it will stay there so is just a little
bit odd it's really really odd that it
happens sometimes and other time so
maybe it's something to do with
something that's switching on that
source button or whatever's responsible
for that source button isn't shielded or
grounded properly very very odd probably
when I was in there last time I bet I've
taken some foil away from something
where it's not grounding one of the
boards properly and my dad would have
just never noticed because he would have
it on quite loud because he's harder
hearing so uh yeah but interestingly it
hasn't dropped out at all and since I've
uh been to my dad's this only lasted a
couple of minutes and then when I
brought it back I think the most I would
have got out of it would have been maybe
four or 5 minutes so now for it to have
been on must be 45 minutes to an hour
and it's still working fine so uh yeah
for some reason it looks like those
capacitors may have fixed it even though
they're testing fine what I've done is
I've ordered up the correct ones I went
for Panasonic I ordered up 20 of them
for around £6 something and uh uh
they're supposed to be low ESR they're
the 105 degree ones so hopefully they're
going to be better than the ones that
are in here at the moment well it is a
bit of a strange one but today this is
the first time where it's just been
working nonstop up until this time and
my dad's it was only working for about a
minute when I got it back to my house it
seemed to work for about 3 or 4 minutes
and then start boot looping so we can
say it's fixed I'm just wary about
intermittent faults if I had seen a
bulge capacitor that I took out or one
with high ESR then I would say yippee I
fixed it but the capacitors I took out
all look to be okay yes one did have
slightly es High ESR for a couple of
seconds but then settled right down
realistically it was probably something
to do with my meter or the leads
touching each other or the can of the
capacitor with a bit of paint missing or
something I think that the wine is
nothing at all to do with the boot
looping I think the wine may have always
been there and maybe it's been there
from the very beginning because maybe I
didn't notice it before I was just you
know checking to see if things were
working I probably weren't concentrating
too much on the wine it's just that the
wine is uh it's quite off-putting when
you hear it but it is only happening on
the CD sometimes it will happen on other
things but then if you switch back and
back again then it's gone but it's
always there on a CD no matter what so I
do spend a little bit longer on the wine
I'm wary about sticking my hands in this
quite clearly when it's on so what I do
is I measure the voltage and it's
actually only running on 15 volt so at
least now we know it's 15 Vols it runs
on so it comes in on AC Mains and it
gets dropped down to 15 Vols DC so what
I do is I unplug the mains completely
and disconnect the lead from it and I
use my bench power supply to power this
now it's only on running on 15 volts DC
I don't have to worry about my hands
going in there and getting electrocuted
so I put it back onto the CD and I run
It Off the Bench power supply and
basically I touch all the different
components hoping that when I touch
something the hum will go away but it
doesn't so maybe this hum is being
generated internally somehow weird thing
is it's the speak it's coming from the
front two speakers it's not from the
subwoofer at the bottom it's definitely
the front two speakers but it's not the
speakers because when I swap them over
and unplug them if I unplug them both
there's no hum coming from the subwoofer
so basically it's only when I have I can
have one speaker plugged in the right
hand one I'll hear it I'll unplug that
one plug in the left one and I'll hear
it I can swap them over and I'll still
hear it the hum's coming from the board
somewhere but it's not from vibration so
when I touch the different coils and
stuff it doesn't change the hum so
unfortunately I can't show you what has
caused the hum on the CD player but
hopefully if you read the comment
section CU I appreciate that's the only
really interesting part of this video If
you read the comment section hopefully
somebody else who's more intelligent
than myself which isn't too hard will
hopefully have a good educated guess at
as to what the problem could be so if
you're curious have a look down at the
comment section hopefully other people
will have answered what I couldn't
answer I also try to use the scope
because one day I would love to be able
to use the scope to see something and I
think that would look great in a video
problem is I'm putting the scope on AC
on both speaker outputs and I can't see
anything there's no spikes happening at
all and then when I put it on the other
one I can't see it either then I put it
on to DC just in case there's some weird
DC leakage cuz I don't know what DC
leakage would sound like on a speaker I
don't know would it be like clicking or
something or whether it would create
like a uh a sound like we're hearing now
a wine I really don't know I don't think
it's ground hum because as far as I can
see the frequency is wrong so I don't
think it's to do with some different
grounds between the boards uh bottom
line is I just don't know what it is and
I can't pinpoint what the problem is so
anyway back to why this seems to be boot
loop in I think it could be something to
do with the cold cuz my dad's house is
definitely colder than mine so what I'm
going to do is I'm going to go to bed
now because it's late but I'm going to
pick this video up tomorrow and I'm
going to leave this outside because it's
winter here in the UK at the moment and
then if I bring it in from outside and
it starts boot looping we know it's
related to temperature and that might
give us an idea that one of the
capacitors are failing on the main board
so let's pick this video up the next day
when this has been outside for many many
hours
right so next day now or next evening
this has been outside for most of the
day it must have been out here for about
6 hours and it is nice and cold to the
touch so this has to now be colder than
it has been at my dad's house so let's
bring it in and see if it's boot looping
if it's not it means that somehow those
output capacitors that tested okay must
have been at fault and if it starts boot
looping we know it's nothing to do with
those output capacitors right you can
see how cold it is because it's actually
got
condensation on the glass there there
look at
that yeah so that's proof that it's cold
let's plug it in probably end up water
damaged now let's see if it's going to
work so turn it
on let's see if it's going to boot
loop connected it's looking
promising here we go
amazing
copyright and right now I can't hear
that sound just out of curiosity but I
can't fix this one
CD
oo that's interesting right now I can't
hear the sound how weird is that maybe
it's somehow temperature
related let me put it back to internet
and then go back to CD again
and now back to
CD it's so bizarre yes it's not making
that sound well maybe the sound only
occurs then when the unit warms up so
that might give you guys a clue as to
what the problem could be cuz I really
can't work that one out and also I can't
work out how to for find that so if
those of you who are more experienced
which is going to be most of you if you
could let me know what you think how you
would for find that because I think that
would be quite
interesting right okay just before the
end the video I'm just going to leave
this on for about maybe an hour and then
uh if it's still working I think we can
say it's fixed but how bizarre is that
when the correct capacitors arrive I'll
pop them in but I might be speaking too
soon yet let's leave it a good while and
see if it is still
working right well it's been at least an
hour maybe longer now and I had it on at
my house for half an hour and it's been
on here for about half an hour and it's
still working absolutely
fine and I've tuned in loads of other
channels as
well that took his
time there we go
so it's back in its home hopefully it
will keep working but I don't really
know why those capacitors fixed it
because the ones we took out were T
testing absolutely fine so I can't
really say that it is fixed but time
will tell my dad's going to use this a
lot more than for example the testing
that I was doing so I'm going to know in
about a week or so if it is still
working if it is I'll change out the
capacitors to the proper 25 volt ones
the Panasonic ones rather than those
cheap Amazon ones and then hopefully it
might keep on working and then if it
fails in the meantime at least I've got
more information to go forward if any of
you out there know why we had that 3,000
htz hum the 3 khz hum then if you could
let me know I'm just going to see if I
can hear it now let me just go to
CD no I can't hear it at all isn't that
really really strange so uh yeah there's
a lot of unanswered questions not the
most interesting video in the world but
at the same time I think the hum thing
is quite interesting on how you would
actually F find that so yeah that is it
for this video the end story is that
somehow it's working when it wasn't
before which is is always good but it's
always nice to have a full conclusive
answer rather than just guesswork
hopefully on the next fix we will have
something more conclusive right just a
quick update at the end of this video I
can't speak about the loud wine because
my dad wouldn't be able to hear that but
this is well over a week later now it's
the 14th of Jan I think I filmed this
around the second third or fourth I
can't rightly remember but it's well
over a week later he's been using it
every single night and sometimes in the
day and it's been working at absolutely
fine now the reason I jumped straight to
the output capacitors is because it's
not the first time it's happened in some
of the videos I've done it's come up
over and over again just off the top of
my head I'm thinking of Phillips air
purifier I'm thinking of Bowers and
Wilkins zeppin speaker Xbox One S
original Xbox I'm sure there's going to
be countless others as well and the
great thing about it is anything with an
internal power supply has the potential
to have the output capacitors gone so it
doesn't matter what the device is if
it's got an internal power supply and if
it's going to be a switch mode power
supply one then whether it's an
expensive Bowers and Wilkin Zeppelin
speaker or whether it's an old original
Xbox there's a chance that the output
capacitors have gone so it's a it's a
good thing to remember so even if this
video was a bit boring if you remember
it then in the future you might go on to
fix something else and hopefully I will
as well because the output capacitors in
this instance look like they were to
blame because I'm thinking the fork
would have read it L head by now because
it's been in use so much and before I
changed the capacitors it was failing
all the time so I think I can safely say
it is actually fixed which is fantastic
the proper capacitors have now arrived
so I need to uh sort myself out and get
them soldered in but it just seems to be
working fine with the capacitors in
there but obviously because there's such
low voltage rating then I suppose it's
going to be very close to the mark where
they're probably going to fail quite
easily so they will be changed so that
is it for this video thank you so much
for watching and I will see you all very
very soon take care everyone
