A friend of mine bought a 50-inch Dell plasma hdtv over 18 months ago. The tv had always been sitting on a tv stand. Suddenly this week, he is seeing color bleed, after glow and dead pixels on the screen. He switched between cable and DVDs and confirmed they were not due to the source. It is passed the warranty period. Can the problems be fixed or should the tv just be replaced? Please advise.
Thanks
