50 somthing inch panasonic hdtv projection tv turns off after a few minutes

Hi I have a 2001 50 somthing inch panasonic hdtv projection television, my friend gave it to me because their dog chewed the cord off. so i went and bought a new cord and hooked it up, but when i turn the tv on, it only stays on for about 2 minutes and then it shuts off and the only way to turn it back on is to unplug it and then plug it back in. but it never stays on. please help, i have no idea what the problem is. my sister told me to take out the chewed on cord and resoder the new one right to the tv. i haven't tried this yet, do you think that could work?

Nobody throws a HDTV away

Nobody throws a HDTV away just because the linecord is bad. 

Sounds like the set is going into shutdown for some reason.

I had a similar problem with

I had a similar problem with my PT47x54j, well just the turning on and off problem.  It turned out the circut board for the on tv controls was bad.  You can open the back of the tv and crawl in and unplug the plug that powers the board and see if the problem goes away.
