    Re: 55” Samsung LCD LED TV Model LE55A956D1M with Static Horizontal Lines

    Probably related to the drive to the gate common drivers (runs along the left or right) if a solder joint failed under one of the COFs then it would possibly disrupt the drive signal for a repeated part of the screen.

    It seems that the signals for the gate drives pass through the left or rightmost tab bonds, so a failure there generally leads to a fault with the rows in some way.

        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...

        by x_orange90_x
        I posted about this previously but didn't get any response, and I have some troubleshooted a bit so I have more info.

        The screen is full of horizontal "gaps" or lines that distort the picture badly, and after about 10 seconds of powering it on the screen starts to fill with red vertical bars that take on the horizontal pattern. After the screen filled with the red bars, they instantly vanished and then slowly started to reappear. I initially thought it was tab bonding failure, but after getting down to them and pressing each one I find zero change in the picture. I went...
