Does the set still have backlight? That is, if the set is turned on and the room is dark, can you tell if the LCD screen is still getting power and lighting up (just with no video)?

Common problem on this set is the main board p/n AGF33761101. However, you might try a 'quick fix' mod on this set which involves locating and bypassing components.
I do think that the replacement board just have these 4 coils bypassed on them already, so you might be able to save some $$$ if you're electronics-savvy by removing and discarding coils l4010, l4011, l4012 and l4203... then jump the solder pads they were on with small bits of wire, making very sure not to short to ground. Good luck!

There is 4 capacitors on the power board that need to be replaced. I have fixed 2 of these in the past now, with the same problem. They are green in color.
Testimonial: "You are so right. I had all the capacitors tested at my place of work. There were actually 5 that were bad. Replaced all for 20 buckS, THANK YOU!"

Maybe!! It depends on where the audio sys failed. If it failed at the output drive, then you can take the audio off at the audio output jack and input it to your stereo system where there is an audio input. You'll need a cable with RCA jacks on it for this.
If your system is muted for some reason, this may not work.

I had mine for 2 years and the main board went out. Cost 650 dollars to fix. Its been less than a yr and a half and it went out again. Selling it on ebay for parts...
