There is no sound
Look at the top of the main board. There are two capacitors together. Look at the area just to the top of the board and behind the capacitors. There is a very small resistor(flat) soldered to the board. I had the same problem, so I removed bad resistor and replaced it with a 10 ohm resistor from Radio Shack. Sound is back. Cost a couple of bucks and took about an hour in all. Hope this helps.

Great picture but no sound.
Check to see if sound when a DVD via the rear inputs is played--rules a lot in or out.Also look in menu to see speakers did not get switched to OFF.
