    Nec E557Q lines and fade to black picture FIXED

    Trash picked this tv from a local business, had a garbage image and would fade to black within second then cut off. It would get shorter and shorter every time.

    Narrowed it down to the right side of the panel by unplugging half the t con
    One side had a great picture the other was black and distorted still.

    Down to the buffer boards… found yet another set of two esd diode arrays. One leg had a 60 ohm short to ground and would get lower the more attempts made to turn the tv on.

    Soldering iron and some chip quick knocked both of them off and replaced with the left over ones from my 65” Samsung tv repair that had the same issue.

    Wallah it works again perfect image!

    Check those esd tvs diode arrays before assuming anything else or a bad panel.

    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 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...

    Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
    by TR103
    Hi, I have a Samsung UE50TU with:
    - sound and backlight, but no picture
    - when it arrived, it had a picture for a few seconds
    - it keeps rebooting
    - without ribbon cable between the two panel boards, it does not reboot but I have no picture
    - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
    - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

    - without cable between mainboard and lcd panel and with a jumpered...

    Screen Display Vertical Multicolor Lines
    by Stanley1843
    Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...
