    Try cooling down things with freeze spray, or heating up with a hairdryer, to make the problem occur quicker/slower and try to locate a single cause.
    Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
    For service manual, schematic, boardview (board view), datasheet, cad - use our search.

      The problems with AS15-F are gamma related, and from what I know are permanent. It might be a cold seam somewhere.
      Please post some pictures with the boards/bad image.

        ASUS ROG G750JM turns with no image and turn it's off within 7 seconds
        by waakye
        Hi everyone,
        I was giving this ASUS ROG G750JM that exhibit the following behavior:
        When you press the power button, the computer turns with no image and turn it's off within 7 seconds. The battery charges when I connect the AC power. I tried flashing the bios with the uSB method and pressing Ctrl + Home and I can see the bios upgrade on external monitor.
        My issue is the laptop doesn't stay on for a long time and turn itself off.
        Any lead on how to resolve this will be appreciated.
        I cannot boot in windows and no liquid damage.

        Thanks in advance.

        Problem with LG Plasma 60PM6700 - Random power downs
        by theone111
        I have an LG Plasma TV 60PM6700 for the past ~12 years.

        In the last ~3-4 months I have been having some issues.
        1. Problem: It started with random picture disappearing (sound still worked).
          Frequency: Happened about once a week.
          Solution: Had to turn off TV wait a few seconds before turning it on again.
        2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
          Frequency: Happened about once a week.
          Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
        3. Problem: TV shuts down

        Lenovo Legion 5 15IMH05H No Display
        by Rolin
        I have a Lenovo Legion 5 15IMH05H 81y6003yUS that someone asked me to help them with a failing SSD. I installed a new SSD, fresh Win11 installation, updates, etc. Very standard stuff and everything was completed. He said he'll pick it up in a few days so I shut it down and set it aside.

        A few days later came and now it won't POST an image, keyboard lights up, fans spin then shuts itself off after about 40 seconds. I've already tried the typical draining capacitance and removed CMOS battery,etc. No display on an external HDMI monitor as well.. No idea what happened. Suspected a BIOS...
