      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...

      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...
