Lg55uh650v horizontal lines

[Ronandoran]

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?

[Ronandoran]

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.
