Hello.
It looks like you ignored lamp replacement in your TV. It have to be replaced every 2.5 years of average use. It's like oil change in a car. Regular scheduled service.
You can read info about lamp replacement in your TV owner's manual, buy lamp on-line and replace it by yourself to save some money.
Regards.
Russ.

REPLACE LAMP

Try replacing the ballast next. Its the small circuit board directly underneath the lamp housing. You can access it through the lamp door. If the ballast is overheating or has a leaking capacitor, the tv won't stay lit for more than a minute or two.

The lamp needs to be replaced.
