    LG 37LH7000 vertical lines, no image

    Hi guys! I don't have a lot of experience so ask you to help the TV has vertical lines, no image, sound ok. T-con is changed, no effect. Cables are cleaned, no effect. I've also checked all pins on t-con going from main to t-con. Voltages on main seem to be ok. Bad panel?..
    sorry for pic. don't know how to turn it
    thanks

      Yes this looks like another bad panel, I'm afraid.

              TCL 50S535 bad tcon or panel issue?
              by x_orange90_x
              Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

              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...

              Strange LG TV issue : Image vertical lines in black screen
              by Ancient1
              Hi

              Asking for a friend.

              I'm used to black vertical line in otherwise good image - probable solution is a rubber to push and tighten the COFs bonding.
              but here its the opposite !

              TV has new T-con = same issue
              A missing panel voltage would have global effect

              So , what should one do ? how can I find where the fault is ?

              Thanks !...

              Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help Needed🙏
              by Daren87
              Hello everyone,

              I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

              samsung ua55es6800 - no image
              by shlomim412
              hi
              having problem with samsung ua55es6800

              tv had backlight on, sound working - responds to the remote control but no image.

              check tcon board - had 12v in but no other voltages present.
              when disconnected left ribbon cable - got back voltages and half image with lines and distorsion

              when leaving only left side connected - again no voltages and no image.

              put a tape on all (cd?! lines) on the left ribbon cable and got complete but distorted image (horizontal lines).

              kept trying to block less pins on the left ribbon cable...
