    Lg55uh650v horizontal lines

    Hello. Sorry to bother you all but I hope you can help me. I have an lg tv with black flickering horizontal lines running across it. I've done a soft reset, hard reset and update on the webos but it's still the same. Can anybody give me any tips or suggestions?
    Thank you

      Probably the panel. Less likely the TCON board.

      Check for damage on the screen somewhere. Have you been using spray on the screen to clean it?

          No Easy. I literally just got it. The guy told me it had a line at the top but I got it home and that's what it looks like. Checked for damage but seems fine.

              Yea one line turns into many. Likely the panel. Transportation probably made it worse

                  Disconnect one of the two lower cables going to the panel from the T-con side and turn on the TV, look at the image, then connect the first and disconnect the second and find out which half of the panel has the defect.

                          Might not be the problem, but have had a similar line pattern that was due to a bad/loose tab bond, "fixed" with a shim. Suppose good strong non-conductive tape would work too. Maybe try cleaning the tcon flat cable ends with isopropyl alcohol, some use a pencil eraser, not too roughly they can be delicate.

                              Samsung QN70Q6DTA Ghost or horizontal lines after tape fix horizontal line
                              by Ihandyrepair
                              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,

                              Sony XBR-85X950G Gray horizontal lines and vertical picture shift diagnosis?
                              by noisykid
                              5.5 year old 85 inch Sony Bravia X950G started showing gray horizontal lines across the bottom of the screen and the picture shifts slightly vertically when it happens. The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...

                              Physically bending the T-Con board creates horizontal dotted lines on OLED55CXPUA
                              by fredtred
                              Hello!
                              I have been trying to solve this issue the past 12 months to no avail. I have been a lurker here during that time but finally decided to post my problem and see if anybody knows a solution.

                              Problem
                              My tv (OLED55CXPUA) has an issue where it displays horizonal lines of dotted artifacts.

                              (See Attachment 1)

                              Self Diagnosing
                              After a very long troubleshooting period I traced the issue to the T-Con board. If I gently flexed/bend the board I could make the display go from GOOD to BAD and vice versa. I have ruled out the connectors/wires...

                              LCD Tv starts to display black horizontal lines after half an hour of use
                              by Gjackson
                              Hi, I have a sort of old Grundig LCD Led TV that starts to display black horizontal lines after some use. After it's been turned off for a while and cold it does not display any artifacts however after some use it starts to display some faint horizontal lines at the top of the screen and a bunch in the middle of the screen. The longer the tv is on the worse they get until they become very clearly visible. I suspect that heat has something to do with this as when the lines start to appear i notice that the tv's metal case has gotten warm. Could the T-CON start to malfunction when it starts to get...
