Television and Home Theater

I have a 1 year 9 month old Sanyo DP42746 42" plasma TV.  It has been working fine till the other day, the screen went black and then the sound went silent.  Now the only thing that happens is the little power light comes on when you press the power button or turn it on via remote, sometimes you'll get a crackle from the speakers when you turn it on.  There is a light on the inside that flashes that I can see through holes in the back of the TV.

This is amazing of how many people are having the same problem. I have the Mistubishi WS 55813 and I cant get it to turn on. This flashing green light is all I get. Ive read some other discussions about this problem pertaining to some caps, could someone please help me indicate these.

Thanks

I am creating a picture slideshow using the Click to DVD software.  In the settings section of the slideshow I click on the 'sync music with end of pictures' (instead of choosing a time limit for each picture to display I thought this option it was calculate the time for me).  But the pictures are still displaying when all 3 songs are over and the first song starts playing again.  Am I missing a setting somewhere?
