Big Screen TV turns on the right back off!!!!

My parents recently got a 1080p 65 inch hdtv and given me their OLD(7-8 yrs) 56 inch panasonic tv.  I was watching it(56 inch) in my room a couple days ago and it just shut off.  It shows a red light next to the main power button when it's on standby and green when it's on.  Well after it shut off it when to standby so I tried to turn it back on, it would make the sound like when you turn a tv on then in like two seconds shut right back off.  I unplugged then replugged it back in the outlet and tried to power it up again and got the same results.  So I was hoping someone can tell me what's wrong with my tv and is it worth repairing or should I get a new tv? Thanks

Sounds like the convergence

Sounds like the convergence correction circuit or the vertical sweep circuit has failed causing the set to shutdown to protect the picture tubes, But without the model number it would be difficult to get much more specific.

I have a panasonic PT-56HX41 and I'm having the same problem described above. The TV was recently given to me and now went out also so i'm wondering how much it would cost to repair and whether it is worth it or not. Thanks.

One thing i would like to

One thing i would like to mention here, that a tv shutting down can be mannnny different things, there is no one magic bullet that will fix all three of these different televisions. I might suggest that each one of you start your own conversation so the fix information can be kept separate and easy to understand. conversation. Larry and I and other people here, i am sure, will be glad to help you. but organized will be better.

The same exact thing happened

The same exact thing happened to my television a few weeks ago. I ordered new home theater systems for the bedrooms in my home. I purchased them from http://www.thebigscreenstore.com and the prices were perfect.

We have a Philips 50" and as soon as we turn it on, it will come on for a few minutes then the screen will go black. The sound will continue to play but there will appear two red lights that look like a key and a light bulb on the power button that will come on. Any ideas?
