meron tayong TV rito na
Sony Sony Bravia mga idol teting natin
kung anong problema nito
magpadali na
lang nagpapatay si hindi mga idol o Ito
pala ang pinakaproblema nito nagpapatay
sindi Al right
tara
ay yan mga malupait mga kam malupait
Ayan bale yung sensor po pala sensor
nito ito dve ito eh
backlight lilan sa pin number 31
magkakabit tayo ng 10k resistor papo
sait na yan naconnect
y Maglagay tayo ng resistor na
10ang ground para po sa purpose para po
sa sensor po niya Hindi po si Mak ng
kung anong konting problem
sa mga hindi pala sanay maghinang ha Ito
tutorial lang naman Ong tinuro ko sa
inyo Pwede kayong matuto kahit dito lang
kayo manood masilan po ang paghihinang
nito dahil po sa napakaliit po ng mga
Ayan nakikita nian Napakaliit ng mga
terminal niya mga
idol once po na magdikit yan ay alam ni
na mangyari umpisahan natin paghinang
mga
idol unang-una Siguraduhin niyo na
malinis yung
dahil bago rin bago ito malinis talaga
to lilinisan natin to idol
yan bago natin Ikabit yan kita natin
ikakabit
to
y so Ayan mga idol naap na natin yung
10k na resistor no ngayon naman mga idol
kung napapansin niyo to Itong mga
terminal
na' Dito tayo repair yung kinabit ko
naman na resistor abang lang po
yan dahil po itong Roll ng backlight
niya tinatawag na Spider IC d ito
Papalitan na to pero hanapan natin ng
paraan ' na ma-repair no kaya meron
siyang purpose dito na kung in case na
nagkakaroon ng problema itong control na
to
yan Panoorin niyo mga idol kung paano ko
ito sosolusyonan So yun mga idol ito ang
gagamitin natin
[Musika]
so ang gagawin natin pagdugtungin natin
yan legit po ito idol yan Yan talaga ang
purpose niyan Yung ito Panoorin yung mga
loads
Ayan kailangan ng konting ingat dito sa
paghihinang mga idol hindi lang tayo
basta-bastang
sabihin natin na marunong Tay
maghinang hindi ho ganon kadali
yun May technique po diyan mga idol kung
paano ka maghinang ng
malinis kailangan lang po
ah initin muna yung paghinang niyo bago
niyo lagyan ng
Ayan right
ah
[Musika]
k
right
yun Ayan po siya Pasensya na sa ingay
mga idol
ha open area po kasi yung pwesto natin
So yan mga idol ako
nahinang na po
natin Oras na para i-testing
yan mga idol Okay na
siya my
god
Wow h
