Question about Sony Televison & Video
I assume this is an LCD or SxRD projection TV... you need a lamp. The lamp's burner is worn from use and when it becomes hot, expansion occurs and the lamp extinguishes. The TV will attempt to reignite the lamp 3 times after it goes out. If successful, it will continue to operate until the burner expanded too far once again. This will repeat over and over. Eventually, the lamp will not come back on. Order a lamp and replace it. Best wishes, I hope this was helpful.

SOURCE: TV Turns off and on
How long since the last time the bulb was replaced? It sounds like the bulb is overheating and triggering a safety shutdown.
It's probably in need of nothing more than a good cleaning (open it up, clean off the boards with a can of air) and *may* be time to replace the bulb.

HI, this may be a simple cooling issue. try inspecting the cooling fans that are located near the power sector. if these cooling devices are not operational, they will cause the power board to shut down periodically, due to heat build up.
If the fans are operational, this will confirm a weak and defective power power board.
