The blinking light is a clue. Whenever a Sony TV's proc receives a fault message instead of a go message, the light blinks. Cold solder connections in the power supply can cause this, but it isn't the most common issue. Component failure in the power supply is more common. Finally, anything in the entire TV can cause the proc. to go into "fault mode" and make the light blink.

If the unit is out of warranty, hire an independent. The warranty centers tend to overcharge cash customers because the manufacturers don't pay enough for the time they spend doing warranty work. At the end of the month, this model works out for the warranty service company, but the consumer is footing the bill.

Wish I was in NY to help you. I made the decision to drop warranty work for this very reason.

Hope it's just a cold solder joint!
