I've had a Yamaha rx-v3900 for the past 5 years now and all of a sudden it's developed a problem.
The issue:
I'm only getting sound from one (right-side) speaker at the front. At first I thought it might be the speaker and so I tried different inputs (CD, BD, cable box, phono) and found that on some inputs such as BD and cable (audio and video) I'm getting sound from all speakers, but when I change to other inputs like Phono and CD, I only get sound from the right side speaker(s).
I also tested different audio settings such as 7 channel and Yamaha DSPs, and the same issue arose. For example if a CD plays using 7 channel enhanced, there's no sound out of the entire left speakers (front, Surround, rear surround) - only out of the corresponding right side. On pure direct the same problem arises - the problem all depends on the input source.
We had a power outage recently - although the unit is plugged into an APC power conditioner and I have a whole house surge protector. Nothing else was damaged (eg computers, Tv etc) so I'm not sure if this has anything to do with the issue.
Also, the receiver is in an open rack with plenty of air circulation so again I don't think this is an issue.
This is the second Yamaha receiver I've had and it really surprises me that it has an issue like this?
Has anyone come across this before?
I assume this means something has blown inside?
Does anyone have a solution (other than buying a new receiver)?
