              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...

              Hisense 40H4F no backlight but turns off after splash screen
              by frannyjunk
              So I have this Hisense tv where the backlight does not come on. But when it is turned on, when I shine a flashlight on the screen, I can clearly see the splash screen then it turns off. I looked at the mainboard and was expecting to see bulged capacitors, but they all look fine. I unplugged the backlight from the mainboard, and get the same symptoms (i.e. no backlight, dark splash screen then just a black screen). Is this just a backlight issues? Do Hisense tvs turn off by itself if the backlights are unplugged or are bad? Or is this a mainboard issue?

              TIA.

              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.
