This problems most likely causes by the board that call the T-CON decodering board.This board sit at the bottom at the middle of the LCD screen panel decodering the codes before sent it to the LCD screen panel for a picture.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish T-CON decodering board for the replacement.
