    Hitachi 50HYT62U - Lines on Picture

    Hi
    Turning my attention to this pile of bullox from vestel, fault is:
    Faint horizantal lines on all pics/extensions...
    3-4 vertical lines on all pics/extensions...

    All caps etc on driver boards are testing ok, screen tabs are not heating up,
    some sprayed freezeit on t-con & main board does no effect, Lightly jiggling the lvds cable does make the pictures colour go odd but no effect on the lines...

    I'm now searching for new firmware to see if this will cure the problem, this failing is there another common cause that can do this, a naff t-con board maybe?

    i've attached pictures & will update on the update if & when I can find the software,
    cheers in advance

    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...

    BenQ 2765HT vertical lines, no picture
    by hendue
    Hello everyone,

    I was trying to fix the monitor, which was giving me the following pictures:

    It was somehow reactive, such that if I pressed the buttons, the lines changed in positions or if i moved e.g. a task window, it would somehow change the patter, too.

    I swapped out the mainboard without any luck. So I thought that it has to be an issue with the panel itself and was trying to assess whats wrong on the control board of the panel.

    Somehow, I managed to short the LVDS protection with a MOSFETS cooler on the PCB.

    I turned around...

    Hitachi 55HDS69 55" Plasma TV - No Picture But Sound
    by KYBOSH
    Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
    No picture but you hear the TV static (white noise) playing loud and clear.
    The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
    But it seems they didn't get too far and just left it.

    When I first took a look I was amazed at how pristine the inside looked.
    Its as if the TV had been in a time capsule.
    Caps looked like they were just pulled off the self.
    Copper coils had no sign of corrosion on...
