Samsung plasma 51" TV 2 years old..was working fine until I left the room and came back and no picture. Cannot turn on manually or with remote. Red light flashes in left corner. What happened?

Look at the manual or call their support.

Very possible bad news... probably psu or main board.
If you are plugging it into a multi outlet power cord try another source.
