Jim,

It may (probably) blown. I'v seen cracks like this on older sets that are 
working fine. I'd replace it though, shouldn't be expensive. 

Peace,
Pat

According to shopjimmy.com (parts purveyor) this isn't too hard. I have a 
"free" LCD that the picture suddenly went out on while in use. Reportedly still 
had sound, but since the sound input source is menu driven, and I can't see the 
menu, I have not yet been able to have it spit out sound.

The above webpage says if you can see the menu display in a dark room with a 
flashlight pointed at the screen, the problem is the inverter board. I replaced 
it for $40 and...no change. So now I'm thinking it's the power supply to that 
board.

The low voltage cabe tests fine. There's a high voltage line with no specs so I 
can't test it. But there's a capacitor right next to the transformers that 
looks like this:

Is that blown, or just poorly covered?

The power supply is out of stock, probably permanently.
