There is a trouble on power supply board. You must check it. If you do not have experience on electronics repairing I consider you should search a tech. I would recommend you www.tvrepairjacksonvillefl.com but you should search near your zone.

You have a power supply problem it is not the sort of thing that you can fix--take it to a dealer or check the small ads in your local paper.
WORKING ON TELEVISIONS CAN BE FATAL.
