Hello, I'm Shahid. Sorry to hear that you're having trouble with this and I'll do my best to help

Can you provide me a picture of TV screen so I can see the horizontal line problem myself that will help to diagnose it a bit quickly?

TV Technician: Shahid, Technician replied 6 months ago

Thanks for the picture, TV screen has multiple vertical lines too along with one horizontal 6-inch wide white bar

Shahid - sorry its only the horizontal line approximately 6 inches in width - no vertical lines ( the earlier pic shows Vert. lines maybe thats from the program at the time when the pic was taken) - anyway no vertical lines issues
TV Technician: Shahid, Technician replied 6 months ago

OK, please find attached picture where I marked vertical lines and if lines are there then the display panel/ the screen will be replaced.

Regarding horizontal white bar, this kind of problem mostly occurs due to the failure of the logic control board, I'm not sure if the logic control board is separate in this chassis or embedded on main board, a picture of the exposed rear will be helpful to pinpoint logic control board in this TV.

Can you provide me a picture of the rear of the TV showing all the circuit board there?

Customer reply replied 6 months ago
ok - give me a little time to prepare and remove the rear panel to exposed the circuit boards - then snap a pic - please standby
TV Technician: Shahid, Technician replied 6 months ago

Sure, please take your time

Shahid please see attached pic's - is the Logic Control Card the center with the 4 each ribbon cables?

TV Technician: Shahid, Technician replied 6 months ago

Exactly, that is the logic control board, reinsert all 4 ribbon cables on it to refresh the connections then turn On TV power to see if any change occurs?

If problem still persists then need to replace the logic control board with identical one, use complete model code of the TV to search/ google it, if this doesn't fix the problem then we are looking at defective display panel/ the screen that is most expensive part of a TV and may not be a feasible repair.
