Report "I have a Harmon Kardon-AVR 320, DVD 25, PA 2000. I can't get any sound when trying to watch a DVD. I've tried every setting on each system. The L and R speaker lights blink on the DVD setting of the AVR320. The surround sound speakers don't even light up on the AVR320 display. Every other function works except for watching dvd's. Does anyone have a solution to this problem?"
