    Hp lc4776n

    Here I go again.
    I now have a HP TV/monitor that has a fuzzy semi focused picture with washed colors and thin horizontal white lines that jump around.
    I haven't fully tested it, can't get the components input to work as well as one of the HDMI ports. Cable/antenna in works, HDMI #2 works. Have sound, all functions via remote work.
    The picture is worse when in cable mode.
    The white lines show up only when there is a picture, without any inputs the screen is fine.
    Am I looking at a Tcon board?

      Re: Hp lc4776n

      Ran a few checks, finally took a shot at it being the tcon and picked up one from Shop Jimmy.
      Took care of just about everything, just need to fine tune it using the power off press power button 5 sec. procedure.
      Not a bad set for a total of $14.

          SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
          by JJAAMM
          This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

          Problem
          TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

          SONY BRAVIA XBR-55A8H - White horizontal lines / red LED flashes four times
          by thstuff
          This "free from a friend who was going to recycle it" SONY BRAVIA XBR-55A8H arrived with the bottom center RED LED repeating a four flash pattern. It was treated with kid gloves and was reported to have "just gone dead" and the OLED panel has no dents in the metal frame or cracks.

          Thread https://www.badcaps.net/forum/showthread.php?p=1091829 helped in proceeding as follows:
          1) Unplugged, then plugged set in while holding the remote VOL- and Power to factory reset.

          2) Waited 30 seconds, then pressed remote Power button and "Select language"...

          ASRock N100M, no picture no boot, but semi-alive
          by Exim
          Hi guys,
          I managed to semi-kill an ASRock N100M board after updating Bios from 1.10 to 2.01. It's a zombie now, dead, but not dead.

          ASRock N100M special features:
          - CPU soldered to board, small Intel 12th gen
          - iGPU
          - four POST LEDs

          Problem after updating Bios to 2.01 using the in-Bios update tool: no picture, no boot.
          I am not sure anymore if it booted at least once successfully after updating the bios to 2.01, maybe not, I can't remember. I think it did not.

          Symptoms:
          - no picture/signal on any of the display connectors,...

          Sony XBR-85X950G Gray horizontal lines and vertical picture shift diagnosis?
          by noisykid
          5.5 year old 85 inch Sony Bravia X950G started showing gray horizontal lines across the bottom of the screen and the picture shifts slightly vertically when it happens. The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...

          Insignia NS-50DR620NA18 w/ large vertical lines & no picture
          by srs
          I'm not sure what to do next and came here since y'all helped me fix a 50" plasma TV back in 2014, which is still working!

          A friend gave me an Insignia NS-50DR620NA18 50" TV that suddenly developed large vertical lines on it. He said he had no idea what might have caused it and has replaced it with a larger TV. He was going to throw it away.

          I did not notice any bulged or leaking caps on any board, the voltages produced by the power supply match the voltage that the pins are marked. The backlight leds are working. I have tried cleaning the ribbon cables...
