    Verticle lines on Samsung PN42A400 Plasma TV

    Hello 👋 I have a tv with these red lines. I've tried cleaning and re-seating the ribbon cables but no luck! Tried all 4 on the LJ92-01485 board and on the bottom of the panel. Do you guys think it's the board?|

    It's not a board. Generally unfixable thing as far as I'm aware. Sometimes you can push on a cof cable and it'll make it disappear

      Yup I've tried touching them, moving them, re-seating and cleaning. I'm thinking there is another cause, and not an issue with the screen. But I could be wrong.
      Weird thing is that it looks like they are both at the same distance from the side of the screen. Also they look like they are between pixels.

      Oh, is it possible to swap boards with different revisions? IE: LJ92-01485A <-- B, C etc

        I'm telling you, swapping a board isn't going to fix this. This is a panel defect. But who knows

            Samsung Plasma TV with vertical lines (model PN50B430P2D)
            by afex
            This is my 2nd broken TV I'm trying to fix and haven't been able to figure out... currently going without any working TVs so am hoping to be able to fix one..

            This Samsung PN50B430P2D Plasma has this big block of vertical lines which will fade in shortly after turning the TV on. The lines will sometimes flicker a bit or fade in/out and sometimes it just stays present. The length of time it takes them to appear varies, sometimes its a few minutes and other times it appears immediately after powering on.

            I have attached an image of the TV with these bars displaying....

            by thetonywarren
            Friend of mine has a Samsung Plasma panel with some vertical lines that are starting to form on the screen.....Ive never worked on a plasma panel, so Im not sure what to look for, would this typically be a main board issue, or something else?

            Any help would be appreciated.....Please let me know.......

            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 QN50Q60t lines on screen
            by jeyoung12
            Hi all
            I have lines on the screen...which is an age old problem that can be remedied by watching Youtube videos and getting out the tape.
            My issue (after successfully fixing a different sammy tv with a separate tcon board and isolating the side of the panel...):

            This tv has an integrated tcon...so it is a bit more confusing when trying to isolate the clocks.
            It has a c ribbon and i have taken each end out to see if that will isolate the lines. instead, it makes it much worse ALL over the tv!

            So....i don't know what end of the C ribbon to work with...
