50" plasma sanyo blinks until tv has been on a while
2 years old 2nd tv 1st tv on kept shutting off 1 week old brought back to walmart they exchanged it 2nd tv worked fine until warranty went out. now when you turn on tv it will blink uncontrolably for about 1 hour before finaly able to watch it. every once in a while it it will shut itself off. Could the blinking and shutting off be the power supply? Need help can't afford to buy another tv right now.
Is there a method to the madness? See if it is blinking a specific number of times and then repeating. This could be up to 10 blinks per set. This is a diagnostic mode to tell you what's wrong with many of the Plasma TV's. Also on the back of the TV you will see vents for the fans. If the unit overheats it will shut down. Use some canned air and blow these ports and related fans out. Also try different input sources such as cable then a DVD or VCR in S video port or composite port VS a cable port.
