    Insignia NS-50DR620NA18 w/ large vertical lines & no picture
    by srs
    I'm not sure what to do next and came here since y'all helped me fix a 50" plasma TV back in 2014, which is still working!

    A friend gave me an Insignia NS-50DR620NA18 50" TV that suddenly developed large vertical lines on it. He said he had no idea what might have caused it and has replaced it with a larger TV. He was going to throw it away.

    I did not notice any bulged or leaking caps on any board, the voltages produced by the power supply match the voltage that the pins are marked. The backlight leds are working. I have tried cleaning the ribbon cables...

    Screen Display Vertical Multicolor Lines
    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...

    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...

    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...

    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,
