              Dell G3 15 3500 - Battery bug (black screen and flashing keyboard backlight)
              by HTR-Informatique
              Hello,

              YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

              I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

              On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

              I also changed the screen because the PC fell and the screen was broken.

              I changed the battery with a new and original battery.

              I also had corrosion/oxidation on the...

              AOC U34G3XM, new monitor, black screen with backlight on, possible shortcircuit during dissassembly
              by turmix
              Hello, I'm working on a new deskmod pc project and have a problem with my monitor, an AOC U34G3XM, well, I may have bricked it.

              The monitor was dismanteled and the separate parts parts integrated in the desk. the screen panel alone is on the upper part, and main board/video board + power board on the back of the desk (not enough place on the cover to fit it)
              At first everything was working smoothly, then I decided to change the connexion between the video board and the screen for a longer one. Still working fine

              During another reassembly, I made a mistake, and...

              Asus G712L No Screen Backlight
              by FallenOne008
              Hi everyone, hope all is well. I have run into a problem where my backlight screen is no longer working.

              The original screen was beginning to show signs of faultiness. I believe it was part of the inverter board that was going bad. The backlight for the screen was still functional at this point. Well one night as I was tinkering with the laptop, my idiot self forgot to disconnect the battery from the motherboard. I attempted to reconnect the EDP cable onto the motherboard, and as you might guess, I saw a nice spark from the cable and the port. Don't worry, I'm still kicking myself...

              HP Probook 450 G8 Boardview+Schematics - screen backlight issue
              by trepachka
              I am just wondering if anyone has boardview+schematics for HP Probook 450 G8.

              Computer is missing screen backlight. The backlight fuse must be kaput. I know the fuse is located on the motherboard because we tried a different working screen and it, too is missing backlight.

              Perhaps, if the boardview+schematics are not available, someone can point out where the screen backlight fuse is located. Thanks.

              Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
              by Ryan.man
              Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

              My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

              This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...
