Television and Home Theater

I bought a Panasonic model #TC26LX60 which was made in March 2006. The main video input is not working. Is this a part I can replace or will I need to take it to a professional? What can I expect to spend to repair it?

   I have a 60 inch big screen JVC TV model# AV-60D502 that I purchased new about 4 years ago. About a year ago it just cut off like you had turned it off. When I tried to turn it on the green light at the power switch would come on then immediatly go right back off. I figured it was dead for good. About 30 minutes later I tried it again and it came back on and played good until about 3 months ago. As before when it kicks off it will come back on in about 30 minutes. Now it is doing this very regular. Sometimes it may be a hour before it will turn back on.

Hi ,Im a newby so hello everybody.
