I have a DC-1 with a strange symptom which hopefully someone has seen before I get no output from the left outputs Neither the front, side,or rear left. This happens with any input digital or analog and any input mode stereo analog stereo digital and even AC-3. Center and the right outputs seem fine. The odd thing is when I use the output level adjustment all seven channels work fine whether listning to the white noise or external source hopefully somebody can help me solve this I'd hate to replace it Thanks ion advance Bob
