Hi I have a Westinghouse 1080P 40 inch TV. It’s turns on clearly but then it’s start to show some dark or shadow areas until it goes dark complete. What can that be? Thanks

Pepita Torres  could be a backlight issue as well as a bad power board. I would start by checking the power board to backlight voltages. If you can, give us the complete model number for your TV and if you have already removed the back off your TV, post some good pictures with your question. That way we can see what you see and maybe identify some issues. Adding images to an existing question
