Television and Home Theater

I have a 32 inch Sony Trintron TV 5 years old. It has sound, but no picture. When a picture does show it's for a couple of minutes then it appears to go backwards then disappear. Plus there's a red light it the front that flashes continually. Could anyone tell me what is going on with my TV?
I don't want to toss my TV just yet.

Hi guys,

My first post.

I have a Acer laptop with a VGA port. It does not have a Video or S-Video out. I want to connect the laptop to my JVC analog tv. is it possible to veiw movies from the laptop on the tv?

My laptop has the following: VGA out
My TV has the following:
Terminals: Front: AV input x 1, Headphones x 1; Rear: S-input x 1, AV input x 2 (1 with DVD), DVD component input x 1, AV output x 1

i already have a satellite receiver n dvd player attached to the tv.

So is it possible to connect my laptop to the tv.

I need to fine out were a wiring harness goes. It starts at p880 on the back of the tube. There are 2 points that it could plug into on the main pc board, either p2401 or p402.
Thanks for any help
