    LG 47LN577 with black fading horizontal evenly spaced lines

    So, I have searched the internet for long, high and low and ended up here.

    As the title suggests; there are static repeating black-ish horizontal lines that start from the left and fades away at around 65% toward the right, meaning its length is more than half the screen. The lines are from top to bottom evenly spaced. I can see the lines on the test image, and on chromecast input.

    This is my first time investigating TV errors at this level, and my initial googling led me to believe it was the T-CON board, considering that it has a left-ish problem. But googling even more, and searching this forum I am now uncertain. I dont got the tools to test individual components atm.

    I have tried fiddeling with the T-CON board to LCD cables, thinking it might be a bad cable, and i tried swapping the left with the right cable. No changes. I tried jerking alot with the cable, no help.

    I appreciate any input!

      I tried doing the normal factory reset, did not work.

      I was not able to do a INSTOP reset using the tools available atm, looks like i need a factory remote or a IR blaster for my phone.

        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...

        Samsung UN46C8000XFXZA Horizontal lines
        by x_orange90_x
        I just acquired this 3D LED yesterday and it has horizontal lines on a little more than half of the screen. When I first turn it on it has thin black lines going across that makes the image look serrated, and then shortly after patterns of thicker red lines fade in. If I turn it off and right back on it will reset to just the black lines and the red will again fade onto the screen.

        I initially thought tab bonds, but flexing the bezel makes no difference, and the fact the image sort of resets after cycling power is different. I haven't opened it up yet to actually test applying...

        Samsung QE50Q67TAU - horizontal lines
        by Rubenlily
        Hello,

        First of all I'm new here. While looking I found this amazing forum and I'm very happy I did. Now for my problem:

        I picked up a Samsung UHD QLED QE50Q67TAU from 2021 for $50 knowing it was defective. The seller said it had black lines and that it could get stuck in boot randomly.

        I've tried a new power cable, hard reset, opening up and jiggling all cables, pressing everywhere to see if I get a reaction but I've gotten nothing. I've tried the tape method but I've only managed to get the lines worse.

        I'm no expert but I've done the tape...
