    HP G70-212EM no video output

    Hi everyone.
    I was getting rid of some electronic scrap which had piled up and found an old HP G70-212EM laptop.
    Unfortunately it has no video output and I really have no idea how to troubleshoot it further.
    So, the laptop seems to be booting ( responds to power on/off button and caps lock led also reacts ), the caps under the gpu show power, the USB also has 5V, the hdd spins up. The display's background light lights up, but there is no content on the matrix.
    No HDMI or VGA signals are detected on external display.
    So is there anything I can do before trying to reheat the GPU?

      No image/no backlight? Tried another LCD panel/cable?
      What GPU does it have?

          Backlight is present, but the matrix shows no image ( stays black ). According to the specs, the GPU is "Intel Graphics Media Accelerator 4500MHD"
          The laptop has VGA and HDMI outputs, but when a screen is connected, it does not detect any signal.

              Onkyo HT-R390 no sound output, video output ok
              by FrancescoV
              Good morning everyone,
              I'm trying to repair an onkyo ht-r390 that has no sound output, despite the volume being at maximum, the rest seems to work; the video output signal (coming from an hdmi input) is present, but the audio is absent. Similar situation if I send an audio signal from any input I have no output.

              The firmware reported is the following:
              M:1.00/11107BLP
              D:?.??/????????
              O:1.00/11107AL

              The DSP firmware given the question marks seems corrupt.

              On the BCHDM-0678 - 25140678 - QPWBCHDM0678A0 board the chip that usually seems...

              Macbook Pro A2289 - 820-01987 - No video output
              by anhbanxoi
              Hello,
              I have this MacBook with a pretty clean motherboard battery that has only 4 cycle counts but no video output on screen, even with external screen.
              I tried to restore with Apple Configurator and it can finish this process sucessfully but still no video output (usually during restore with dfu mode a apple logo will appear)

              I also followed T2 power sequence and seem like all power are up and running ( I got this signal ALL_SYS_PWRGD)

              CPU get warm, fan spin, touchpad clicking, no chime sound, current draw around 0.6A without battery.
              ...

              RTX 2080 ti (Zotac - triple fan) - No video output / Vcore / Vmem missing
              by T4H
              Hi,
              I have an RTX 2080 ti (Zotac - triple fan) with no video output.
              So far I have measured the following:
              • PS_FBVDD_PH3_SW = 40 ohm to ground (Micron ICs) - Memory should be fine right?
              • 12V power rail present
              • 3.3V power rail present
              • 5V power rail present
              • 1.8V power rail present
              • Vcore power rail missing --> PS_NVVDD_VREF is present. (from uP9512P / U812)
              • Vmem power rail missing --> Not there because Vcore power rail is missing.

              Any idea? I have already tried to flash the BIOS chip (backup got created) - sadly no changes.
