Hi everybody-

I have a Pioneer VSX-519 A/V receiver that has been working fine, but suddenly lost one channel when an analog input is used. All digital inputs (HDMI, TosLink, etc) work fine, but when I connect my CD player into any of the RCA inputs, one channel is dead. I've changed RCA cables, tried different inputs, and different devices (CD player, MP3, etc).

Any ideas? Anyone have a schematic for this unit?
