Pioneer GM-X84 amp not working

I'm having trouble with getting any signal from the outputs of the amp. It's a Pioneer GM-X84 (4x35w). I couldn't find a wiring diagram/user manual but found the pins were marked on the circuit board. I wired it up using only channel A to power the front two speakers. It has a 12 pin Molex type plug and two rca inputs, one for each channel. It powers up fine, the light comes on and using a test light I found various components in the circuitry are receiving power but nothing comes out of the speakers. I checked the board for dry solder or blow caps but everything looks ok. Does anyone have any suggestions as to what the problem might be? Thanks in advance.

Hey, I have had an issue with an earlier pioneer amp (the model before this?) where the RCA connectors were not getting earth. Try connecting the exterior of one the RCA's that you are not using to earth. That worked for me.
