      Cold solder joints on the flex going to the plasma panel.
      I think Sky were selling these with their TV packages a while ago... Just an LG plasma panel inside.

                  tom i noticed that some silver things on one of the boards are a little bulged, i replaced these with caps on a tv before with power problems and it fixed the board. tried to take some clear pictures. if you need more let me know thanks

                      They're probably OK. They normally look a little like that.

                      Sorry, but your pictures are next to useless, I can't see anything...

                      I need one of the chassis so I can tell you where to look, remember, I don't know this TV or have it in front of me.

                              Great, thanks.

                              Can you get me a picture of the sticker in the top right I've ringed? In fact one of each of the stickers would be useful. I can look up service information using them.

                              Also, I've highlighted some of the visible driver packs for the columns. You will need remove the main board assembly to access the rest of them. Basically you want to unscrew the module, carefully detach the flex, then get me a picture of what's under there (need to know if it has resistor-on-flex or not.)

                                  All left and right refers to looking from rear of TV (or looking from front with TV upside down)
                                  • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                                  • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

                                  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?|

                                  Samsung Plasma TV with vertical lines (model PN50B430P2D)

                                  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....

                                  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.......

                                  by Stanley1843
                                  Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...
