    Lcd fujitsu b19-2 black screen fixed

    I finally fixed my lcd fujitsu 19-2!!!. The problem is the same reported in a lot of forums: the screen turn black just after 2-3 seconds. I suppose that the problem were the capacitors, so i replace all them (someone were an hermei model, but anyone were bulged and they have the correct capacity). The black screen persisted, until i found this http://warrantyvoidifremoved.com/tft-repair: i use a resistance of 3.3kohm in the same position and the screen now work!!!!! I made some photo of the power board. I also found the eletric scheme, but i don't undestand how it exactly works: the problem is on the capacitor of the integrate ba9741f, probably on the pins used for the feedback error.

    PS: someone else has had the same problem? I add that I have not replaced transistor, integrate but only the original capacitors.

      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...

I came around this forum last week with the goal of repairing my faulty gaming laptop, indeed, I was video editing on it when suddenly a black screen popped and never disappeared I bought some stuff to try to repair it and learn as many things as possible about computer repairs but nothing worked so far. When the black screen appeared, my legion 5 pro was connected to my external monitor...

      Hi everyone,
      I have this strange behaviour with Acer Aspire E5-574-52RH, i5 6200U, intel graphics, DA0ZRWMB6G0 Rev G, model ZRW.
      Laptop came in for a SSD upgrade, took everything apart to install the SSD.
      Everything started after modifying BIOS settings to boot UEFI instead of Legacy.
      Laptop works fine, i installed windows 10 and drivers/updates, everything works ok(when it works)
      The black screen problem is random, maybe 5 out 10 times, laptop remains with the black screen, no image

      Symptoms are:
      - random black screen after displaying Acer logo...

      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...
