THE 5 YEAR OLD TV GOES OFF AFTER A FEW HOURS OF PLAY-SOMETIMES WITHIN MINUTES-THE LONGER YOU LEAVE IT WITHOUT PLAYING IT THE LONGER IT WORKS FOR-THE RED POWER LED KEEPS FLASHING WHEN THE TV IS PLAYING-THE SCREEN GOES BLANK AND THE LED STOPS ASWELL-IS THERE ANY COMPONENT I CAN CHECK OR CHANGE?THANKS

Don't know the set but I would check for bad solder connections in the flyback and especially the vertical output circuit if the sound is still present.
