SOURCE: Sharp aquos has green and white vertical lines

You must contact a svc co. This is a upper or lower buffer board problem and possibly a control board. Nothing you have done wrong, it just happened.

Horizontal lines showing behind tv menu


Hello,
Normally the menu is generated in the LCD Control Unit. If your menu looks good, but the defect is behind the menu, I would suspect the Main PCB. Good luck to you. Part# is DUNTKD934FM01-V1.

Thin line across the screen


I'm guessing that this is a CRT based TV, not an LCD. That being said, the problem is a failure of the vertical circuit. Usually this is a small flat IC (LA7837 or similar). Try resoldering the pins if you can first. If that fails to resolve the problem, replace the IC. Please be aware that there are potentially dangerous high voltages present even when unplugged.

Keep us posted.
