If the TV works fine till the time it shuts off, then check if this is thermal related or if with a tap the TV shuts off. If so check for poor soldering joints in the power or relative sections. Use a good soldering iron to touch up all these circuits.
If not there could a component malfunction with thermal action. If so seek technical help if you are not familiar.

Picture shuts off

It seems as though the bulb(s) in your unit are about to go out. This is repairable/replaceable by calling your manufacturer. If you are still under warranty they can help you by possibly troubleshooting/replacement/referrals.

Tv shuts off after 2 seconds

This is made by LG / Zenith. They have had alot of problems with there TV's.It most likely has an inverter board going bad or could be power supply board. It will cost to much to repair. Get an extended warranty when you buy a new one. It will pay for itself.

Tv cuts off and green light flashes

If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!
