Well I just recieved my refurbished Harman Kardon AVR325 and it seems to be giving problems. At first on the display it would bounce from digital to headphone back and forth. Now it wont play and it seems to be locked in headphone mode, two times it would suddenly come out of headphone mode and play then it would go back. Shipping to me was a whopping $100.00, now if I need to send it back and ship it back to me thats $200.00, would I be responsible for the charges? If I turn the volume up to +10 max I can hear the volume a bit and if I leave it turned up for a while sometimes all of a sudden the volume would come to normal again?
