    This would ideally be in the TV forum. Contact a moderator and ask them to move it, if you like.

    Take the back cover off your TV and post pictures of the parts inside.

                How thick are they?

                Very thin lines will be the panel itself (or actually the COF chip driving that vertical part--Its made as part of the panel and not serviceable)

                  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...

                  Problem

                  This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                  Panasonic SA-MAX770PU SMPSU board fault....
                  by Rictech
                  Hello everyone. πŸ˜€

                  As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
                  Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.

                  Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
                  This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
                  There are no devices that have exploded or otherwise show signs...

                  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...
