    Damn, no datasheet for that IC... Not even a pin out... Can we see a picture of around this chip?

        They could have at least labelled some things!
        Where do you measure the 22V dropping to 14V?
        This may be VGH which is used by the TFT to select rows... low VGH = scrambled image.

          I measure that at the two diodes, labeled D7106 and D7107, they're just above the small mosfet Q7106 on the left of the picture.

          What's strange is that the image becomes scrambled so regularly.

            An update, I finally got my hands on a universal remote and managed to do the firmware update...no change

            I've unplugged the CN7102 connector and the left part of the image is stable now, with the right side being white. If I plug the CN7102 and unplug the CN7103, I get the right side scrambled...so is it a flat panel problem ?

              Philips 58PUS8536/12 Backlight ok, no image
              by malekservis
              Hello,
              the TV turns on fine, seems to be working, but shows no image outside of a thick white vertical line as it turns on that also disappears almost instantly, and then it's just backlight. I've tried unplugging either side, but still can't get an image. I suspect it's a panel issue, but thought i'd ask some smarter people to confirm. I haven't found any weird readings, but then again i'm just randomly poking around with a multimeter.

              Any information would be appreciated....

              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.

              philips 47pfl6158k/12 image faded away, sound still coming from TV
              by Kartowl
              Hi, my TV image started showing those lines and the image faded away, but sound is still coming from it, what could be the cause and is it fixable? I thought it could be the tcon board but I red on the internet that it could be a failing panel

              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...
