    Flashing Horizontal Lines on TCL LED55p65US in the Jungle

    I am in the jungle visiting family and I always try to fix all their electronics while I am here

    A few years ago I gave a family a TCL LED55P65US tv, and now i am back and it is having some issues.

    There are constant, shifting horrizontal lines across the screen and the screen flashes every 1.5 seconds or so, as seen in the attached gif.

    Ive been through a few troubleshooting steps and no luck so far.

    Does this seem like a possible T-Con board issue or does this seem unrepairable? The tv has been in a high heat and high humidity area, and the back is VERY dusty (it's the jungle, no AC)

    I'm planning to take the back out and clean off all the dust, clean and reseat the T-Con ribbons, and then possibly replace the T-con board.

    Does that make sense, or should I try something else? Or is this likely a panel issue?

    Thanks for any help or direction

    TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
    by howardc64
    All left and right refers to looking from rear of TV (or looking from front with TV upside down)
    • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
    • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

    LG 82UN8570AUD ~ TCON or PANEL?
    by kca
    Hello all ~

    Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.

    When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.

    I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped...

    Samsung QN70Q6DTA Ghost or horizontal lines after tape fix horizontal line
    by Ihandyrepair
    Hi guys

    I just started fixing 4k TV few months ago. so I am still learning a lot
    I got this tv from friend complaint is ghosting or horizontal lines on image.

    never saw the original symptom but I took the tv back home. the funny part is that after bringing to home, the tv worked fine no issue for 3 weeks.
    then it started to show the ghosting white image.
    I started using the tape method, but this tv does not have a T con board and it has only 1 ribbon cable from main board to the tv panel.
    it has 3 thin small boards at the bottom of the...

    Sony XBR-65X750D Horizontal lines bottom of screen
    by ggil44
    Hi, I have a Sony XBR-65X750D that has horizontal lines at the bottom 6 inches of the screen. These lines appear to be every other line because the picture is still quite visible behind those lines. The lines appear all the time with a few other lines above and below the 6 inch level blinking on and off at about 2 second intervals. I'm not sure if this is a panel issue or power supply/main board problem. I did replace the T-Con board without any change in the problem. Any suggestions you might have would be greatly appreciated. Thanks,

    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...
