My Panasonic TH-58PZ850U just developed a very troubling problem. A thin black line has appeared all of the sudden. It is a horizontal line, no thicker than a pencil point that spans the entire width of the screen about 12 inches from the bottom. My fear is that I have an entire "row" of dead pixels - essentially a defective panel. I've done some searching on this forum and on other sites and the majority of the comments agree with my fear - and also state that the cost to repair this is VERY expensive - potentially involving replacing the entire panel. The TV is only 15 months old and out of warranty. My question is this - Could this problem be anything else that might potentially be fixed relatively inexpensively? - Say... $500.00 or less? I'd hate to pay a service call fee if it is inevitable that the panel is bad and would cost almost the price of a new TV to fix. It would make more sense to just buy a new one, even though it would kill me. Any thoughts or advice would be greatly appreciated.
