I'm sorry to hear that you're having this issue with your TV. It may be an inverter board, or something internal having to do with the backlighting of the unit. I would recommend having the unit inspected by a technician.

Hi - THE PICTURE ON MY TV WHICH IS JUST 30 MONTHS OLD IS VERY DIM AND HAS A SLIGHTLY DARK SHADOW ON ONE SIDE OF THE SCREEN. WHEN I BOUGHT THE TV THE PICTURE WAS GREAT BUT NOW IT IS NOW VERY POOR.
CAN ANYONE ADVISE ME OF WHAT IS WRONG WITH THE PICTURE AS I PAID
