    Phillips 42 PF7320A/37 has horizontal lines and red pixels

    I put in a new power supply and fixed the no power issue,but now I have horizontal lines and red smears even with the menu on.I thought it was probably a bad panel until I saw a green LED blinking on the SSB board.They are 2 green LED's side by side LED 2011 is blinking and LED 2010 stays lit solid.Does anyone know if it would be a bad panel or SSB board?

    This is a bad Y-buffer board.

      ...or boards, they are two. If you have the pink lines on the whole screen then both have to be replaced.
      Each controls half of the screen.

        Yes, though sometimes a bad upper can make the lower appear bad.
        Both should be replaced.

          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-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...

          Physically bending the T-Con board creates horizontal dotted lines on OLED55CXPUA
          by fredtred
          Hello!
          I have been trying to solve this issue the past 12 months to no avail. I have been a lurker here during that time but finally decided to post my problem and see if anybody knows a solution.

          Problem
          My tv (OLED55CXPUA) has an issue where it displays horizonal lines of dotted artifacts.

          (See Attachment 1)

          Self Diagnosing
          After a very long troubleshooting period I traced the issue to the T-Con board. If I gently flexed/bend the board I could make the display go from GOOD to BAD and vice versa. I have ruled out the connectors/wires...
