How do I repair it and where can I get the parts , I have not had any problems with this set before , it has worked great for four and a half years and one morning I turn it on and it clicks or snaps like it does when it first comes on and then a little quieter click and nothing. The small red lite comes on on the front to show its on but isnt. I have tried it a few times with the same results It is Panasonic PT-53WX54 projection set. I like it. Can someone help me repair it?
