I Bought 4 BROKEN Monitors - Let's Try to Fix Them! I bought four broken computer monitors to see if I could figure out how to fix them. I don't really have much experience fixing monitors so these repairs will take a lot of trial and error and experimenting to figure out what's wrong and how to fix it... if it's even fixable or worth fixing.

Who puts a plastic shipping label pouch strait onto a monitor like that? Some people's children.....
I would never call a ‘no fix’ video as boring, as it’s always experience

I must say, while your other console repair videos are fun too, I tend to like these just a little bit better because while you generally know the common issues with the consoles and where to look, when working on this stuff that you aren't really as familiar with, we get to see more of the general diagnostic process which I find really cool.

Even if the board is dead, the screen can be salvaged and be connected to a different screen driver - about 25 bucks to a driver. I made several new screens this way.
This guy is amazing. He saves actually decent monitors from landfill which doesnt seem like much but it is actually amazing
Great video and repair as always! For that last TV with the backlight issue, my first suspicion is usually a bad led(s). The short wouldn't be bad enough to take down the LED strips on the one side but when combined with the load from the other side, there is too much current draw and the driver circuitry shuts down. You could use an LED backlight tester to see the current draw (for ease) and/or you can expose the backlight and potentially see which LEDs have an issue. If it's not obvious at first, you can film in slo-mo on your phone when you turn on the backlight and then replay it for come clues.
For the 1st one - I think you missed the part where some cleaning up is made with solder wick and then put on some fresh solder. I do the same mistake every once in a while - thus the cold solder joint. For the 3rd one - 99% sure , one of the LEDs is dead , so you don't even have to replace the whole strip. Just find a matching LED and put that on the existing strip -> cheap ,but time consuming fix. Take your time with led panel disassembly.
Hey @TronicsFix great video yet again, I love watching would-be landfill getting turned into working items again! I was curious, do you plan on fixing up Steam Decks once they start getting used and inevitably broken? Would love to see that!
These repair videos are so satisfying, as well as the fact you're saving capable devices from landfill.
This is the kind of work I've been doing at the farming electronics company I'm working at and it's so much fun being able to find and diagnose any problems with datasheets!
Great repairs Steve, love your channel
On these cheaper monitors, it’s really not worth it to buy a new screen, but my friend bought a high end 1440p 180hz monitor with screen damage for next to nothing, and replaced the screen. All in all, the unit works perfectly for a fraction of what it would’ve cost new. Your mileage may vary though
I'm so glad you're finally fixing monitors. You seem to really read our ideas when you ask us. 👍🏻👏🏻👏🏻👏🏻
I had an issue with the same chip as monitor 2 , but in my case , the bad chip also caused significant burned traces in the PCB.. Although I was able to manually wire all pins , but the board was so broken that ultimately I decided to replace the PCB itself with a new one ( You can get them for 30 bucks ) , and it even added an HDMI output to my monitor.. Still using that monitor to this day , works great..
great stuff mate, always enjoying your videos, keep them coming!
Thank you for this video Steve!! I always wanted to see you try your hand at fixing some computer monitors. I went through a phase of fixing LCD screens. I put up an add on Kijiji for free pickup of broken computer screens and it worked quite well. I couldn't fix all of them though. Some were just beyond me at the time. I'd love to see ya get some 2K or 4K computer screens to fix. That'd be interesting to see as well, since those are rather expensive units
The backlight LED circuit is the boost converter which is on the right side of the board where the inductor, diode and bulk caps are. It will generate the voltage you need to satisfy the forward voltage requirements for the LED strings in the LCD. If you find the datasheet for it you can browse the reference schematic and use it for clues on how to debug the circuit.
