Sylvania Lcd 32 in.
Is it under warranty by chance?
What is happening is when you turn on the TV, it's trying to power up the screen at that moment. If it can't power up the screen, it will turn off automatically. This is what they call, "Protection Mode".
All the TVs made by Funai (Emerson and Sylvania) are having the same problem. The Inverter Transformers needed to power up the screen are somewhat low quality and burn out easily. I'm sure of of them burned out.
Your TV, I believe, takes 6 of those things to power the screen. And they are all on one circuit board.
If the TV is not under warranty, then let me know what the board number is on that circuit board. The board inside the TV should have maybe 6 connectors that hook up the screen. I may be able to track down a replacement board for you.
