I have the same problem. It could be the circuits responsible for power distribution. I am changing the power pcb on a Bush lcd makes sense as sound kept going when picture turned off and remote kept controlling sound and tuner, all points to power management which has all manor of solid state componants that will fail. Google is the pcb board no printed on pcb next to some components usually in gold on green with the date of manufacture and see what results you get. Good Luck. Ben French
