I have a 90" Sharp Aquos LC-90LE657U. The picture has horizontal lines that get worse as the image move. During a static image, the horizontal lines travel downward from top to bottom. I took it to a repair shop and they told me it has a “bad panel screen”, and want $2,000 to repair it. Google searches tell me there are bands along the perimeter that come un-glued and cause lines but I don’t think that is what’s wrong. This TV has tabs, but they don’t touch anything. (See picture) Any advise on how to get the back working or is it junk? Thanks
@nato41 this does look like a bad panel but you do have to check your boards as well. I do not think this is a TAB error since the lines would look different. It could be gate driver issues on the LCD driver board (part of the panel). Remove the back of your TV and check the boards and the wiring. Post some images of this with your question. That way we can see what you see. Use this guide Adding images to an existing question.
