I Bought 4 BROKEN Monitors - Let's Try to Fix Them!

Summary

In this video, the creator embarks on a journey to fix four broken computer monitors, sharing the process of diagnosing and repairing each one. The first monitor, an ASUS model with a broken screen, is deemed unfixable. The second monitor, an HP 25-inch, faces a power issue due to a damaged chip, which is replaced successfully. The third Samsung monitor lights up but has backlight issues, leading to a deep dive into the board's components without a conclusive fix. Finally, the creator shares insights into using Wondershare Filmora for video editing, while troubleshooting and repairing two out of the four monitors.

Takeaways

• 😀 The video showcases a repair attempt for four broken monitors.
• 😀 The first monitor (ASUS) is unfixable due to a broken screen, which is typically too costly to replace.
• 😀 The second monitor (HP 25") had a power issue, traced to a burned-out chip on the main board, which was successfully replaced.
• 😀 Troubleshooting of the HP monitor involved inspecting the board, using a microscope, and applying flux and hot air for chip replacement.
• 😀 After replacing the damaged chip on the HP monitor, power was restored, and the screen functioned again.
• 😀 The third monitor (Samsung) powered on successfully without any issues, but the user decided to test it off-camera for a thorough check.
• 😀 The fourth monitor had adhesive from a packing label on the screen, which was cleaned off with a 50/50 water and isopropyl alcohol mix.
• 😀 The backlight of the fourth monitor was not working, and troubleshooting revealed a voltage issue with a chip on the board.
• 😀 The user replaced the problematic chip in the fourth monitor but failed to fix the backlight issue, leaving the monitor unfixable for now.
• 😀 Wondershare Filmora is sponsored in the video, offering features like keyframing, motion tracking, audio ducking, and creative video effects tailored for social media platforms.

Q & A

What was the main goal of the video creator in this project?

The main goal was to fix four broken computer monitors that the creator bought to see if they could repair them.

Why was the first monitor, the ASUS 24-inch LED, considered unfixable?

The first monitor had a broken screen, and it is generally very difficult and expensive to replace monitor screens, making it impractical to fix.

What issue did the HP 25-inch monitor have?

The HP monitor would not turn on, despite receiving power to the board. The problem was traced to a faulty chip on the main board.

What specific problem was identified on the chip of the HP monitor?

A large black spot on the chip's leg indicated a burn mark, suggesting the chip had been damaged due to excessive current.

How did the video creator attempt to repair the HP monitor?

The creator replaced the damaged chip using flux and a hot air soldering station to remove the old chip and install a new one.

What troubleshooting method was used to verify if the replacement chip solved the problem?

After replacing the chip, the creator tested the monitor by reconnecting the power and checking if the LED indicator light turned on, signaling the monitor was functioning.

What was the next monitor the creator worked on after the HP monitor?

The next monitor was a Samsung monitor, which initially showed signs of life by lighting up, but the creator still decided to test it further off-camera to confirm functionality.

What issue was found with the fourth monitor, and how did the creator begin troubleshooting?

The fourth monitor had a sticker adhesive on the screen, which the creator carefully cleaned off with a mixture of isopropyl alcohol and water before testing the monitor for functionality.

What problem did the fourth monitor face when powered on?

The fourth monitor would not display an image when powered on. The backlight appeared to be malfunctioning, with only one side of the backlight turning on when one of the connectors was unplugged.

What did the creator discover about the power supply to the backlight of the fourth monitor?

The creator discovered that when one side of the backlight was disconnected, the other side would work, indicating that the chip responsible for boosting the voltage to 53 volts was likely malfunctioning.
