                  LVDS connector had nothing to do with usb error, it may when you taped the eeprom lost connection got tight.

                      It still is not fixed but when I put pressure on lives cable at main board it fixes. How can I make lives connection tighter its the flip close connection. Seems like I seen a scotch tape trick before.will firmware update fix usb problem or should I try to get another mainboard

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

                          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

                          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...

                          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...

                          by pni
                          Hi guys…I need your help. My cousin ask me to fix her tv. The tv when I went to pick up showed 3 horizontal black line. So I know it was a bad panel issue but I could try to fix with the tape method so I said her I could fix easy. When I come back to home, I turned on the tv and now the tv show vertical line colored….and the problem is that I unplug the ldvs cable, first the right side then the left side I still have the lines. The lines never disappear. When the right side is plug in I don’t have nothing on the screen only this vertical lines, when the right side is unplugged I have picture...

                          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...
