In playing this unit, I discovered the Right speaker is not audible, only the left. I tried the following: Checked wire connections from speakers to back of my amp Checked wire connections on back of speaker Switched speaker connections from Set A to Set B Switched out the Right speaker with another After these experiments, nothing changed. Then I played a cd in my other player(connected to the same amp), and have normal sound from all speakers. So...this leads me to believe something is wrong with my Pioneer Elite PDF-19 work horse. Any ideas of what is wrong, and would it be an expensive fix(I do not have the skills or know how, so I would have to send for repair). Is it even worth it at this point? Makes me sad, but looking for suggestions on what the problem may be?
