    Toshiba 50L4300U - Horizontal lines and interlacing issues?

    The Toshiba 50L4300U turns on and seems to work fine except the screen switches back and forth between two states.
    The first has a persistent horizontal black line then it switches everything below that line switches between some sort of fuzzy interlacing issue.

    Is it possible it is the T Con board?

      Panel problem. Not repairable.

              Could this be a side tab issue?

              Edit
              Didn't quite see how fuzzy the picture became until viewing again.

                  what would I check for on the side board? I played around with the ribbon cables to see if it might have been an intermittent connection, but didn't notice any changes

                      At the moment it does look like a panel fault, sorry.

                          Ahh, OK. I will just scavenge parts then.

                              TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
                              by howardc64
                              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

                              Hi all,

                              My TV had been showing for the last year some faint horizontal lines on all of its right side, about one out of each 4 of 5 rows of pixels. Not much of a bother, they were unnoticeable when watching a movie. Then, all of a sudden the horizontal lines became much stronger and crossed the whole screen, effectively making it a pain to watch.

                              I watched some youtube video where some guy "fixes" it with some tape on the ribbon cable of the t-con, so I tried that, but to no avail. Actually, after putting the TV back together again things worsened: apart...

                              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-65X750D Horizontal lines bottom of screen
                              by ggil44
                              Hi, I have a Sony XBR-65X750D that has horizontal lines at the bottom 6 inches of the screen. These lines appear to be every other line because the picture is still quite visible behind those lines. The lines appear all the time with a few other lines above and below the 6 inch level blinking on and off at about 2 second intervals. I'm not sure if this is a panel issue or power supply/main board problem. I did replace the T-Con board without any change in the problem. Any suggestions you might have would be greatly appreciated. Thanks,
                              05-30-2023, 07:51 PM
