I’ve had my Panasonic 60ZT60 for about 7 years. Just last month, the screen went crazy (see pic below). It did this for all inputs and sources. TV Menu behind. Changed electrical outlets. Tried resetting. No luck. Since it is my main TV, I went ahead and replaced it, but I can’t bring myself to get rid of it. Does anyone have any suggestions as to what the problem might be and/or if it can be fixed for a reasonable price? Thanks!
