If you have moved the tv lately it could be a loose cable.Put a folded blanket on a table flip the tv on its screen remove the stand and speaker bar,if it has one.Remove all the screws in the back,remove the back.Check the cable connections between the power supply and the tuner board.If its not the cables its probably the tuner board,the one with the cable connections and rca jacks.Take the tuner board out and check for bulged top capacitors or anything that looks burnt.You may have to replace the tuner(main)board,the part number is printed on the board. |
