    samsung un48j5000afxza choppy picture horizontal lines

    Thank you all in advance. I have a samsung un48j5000afxza that has horizontal lines going through it and the picture skips. I can hear a high pitched sound coming from the tcon board that matches the skipping (almost like a consistent beep). It sounds like electrical noise.
    When I unplug the left side of the tcon board it continues, but when I unplug the right side it stops the skipping, and that half of the screen works fine.
    The skipping high pitched sound comes from the tcon board. There are no swollen caps on the main board. Do you think the tcon board is bad, or could this be an lcd driver or panel issue? Any help is appreciated.

      You need to check the resistance of the caps (to see if they show low resistance) on the tab bonding board, the board that has the LCD flexible PCB's attached to the board and where the flat cable from the T-con board attached to.

          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...

          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...

          Samsung UN46C8000XFXZA vertical bars/horizontal lines
          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...

          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...
