Facing TV Problems? Ask a TV Technician.
Hey welcome to the site. I'm Dan and I've seen this problem many times. To be sure, I really want to see a picture of what you're seeing. Can you take a picture of it, please?
OK. Do you want to order parts (if cost effective... haven't looked yet) and fix this yourself?
OK let me grab my service manual and get some part numbers........ give me a few minutes.
OK, do you have the back of the TV off yet? If not, let's do that.... I need to see the board layout. These Panasonic models have several different versions. I think you have 3 buffer boards along the bottom but I want to be sure....
