Television and Home Theater

 My dads Panny blew up last night, I'm trying to diagnose it. It's red power light still comes on, so I think the power supply is alright, but it might be the screen. He said it "popped" loudly, enough that my dog jumped and ran, what could that be if not the power supply? I'm gonna tear it apart tonight, but does anyone have a service manual or any info on this model to give me? I'd be very appreciative! 

We have a Sony projection television that turns on to the point of sound and then suddenly turns itself off. Whether I use the remote or manually the television starts to come on voice and all.  The sound of my favorite show is music to my ears after a long day, but instead of sound graduating to the televsion screen filling with action, the standby light flashes, and off goes the power.

My 65" rear projection TV will not power on at all. It does not have a blinking green light or any light at all. It seemed to work just fine one day then it would not power on the next morning. I have looked for popped caps but can't seem to find any. The power board looks like it was getting hot in a couple of places (board looks like it turned brown from heat). Is there some test points I can check with a digital multi meter? And what should the test values be?
