    qosmio x200, new gpu module worked 2 weeks

    thats it guys , received a qosmio and client didnt want to spend for a new module and requested reball , ok we have reballed is module , it worked for a few days , than the same only worked on external and no internal.
    he came back and he ordered then to us to buy a module for this computer , we ordered new and guess what it only worked for 2 weeks , now the same issue , works perfect on external , but nothing on internal not even backight .
    we changed screen and lvds but the same issue , in any case we reworked the module , and still no internal .. external runs ok , i was thinking could be a bad gpu , but runned furmark at 1920.1080 during 15 min , worked perfect , ok only at 92 degrees !!!! really to hot . but works fine , so seems weird to be a gpu problem since 3d apps are working fine , even 3dmark !!!
    so now im a bit stuck with this monster , the chip itself is a g84-750.a2, i got vcc for lvds , but n image at all...
    tryed to chek schematic but i only have te rev 01 , and this board is a rev 2b , schematic is quiet diferent
    board is a la-3441p. all tips or help will be welcome.

      Even if it shows on external, it can be just the LVDS part of the chip that fails. It's still a GPU problem. You can try swapping the GPU chips around, as the 2nd GPU of a SLI setup is less stressed.

      After you get it to work, undervolt the GPU and it should last for a good while.

          Replacing the WiFi module on a vacuum cleaner iROBOT i7
          by AlexVG
          Hi,
          I have had an iROBOT i7 with a camera error (error 68) version REV M, year 2018.

          I bought a liquid damaged Mainboard with WiFi module, from the same vacuum cleaner, but a different year and a different version (REV G).
          (This board does not respond, only the LEDs light up in a circle.
          The liquid damage is catastrophic and restoration is impractical).
          (I bought this board to get the WiFi module and camera).

          The boards are completely different in the installation of elements, even the connector for the WiFi module is different.

          If...
