Problem solved. There is a pico fuse on the stereo circuit board near the RCA outputs that will blow if the RCA cables are hot swapped. By hot swapped, I mean unplugged and plugged back in with the system turned on. Apparently Pioneer head units are prone to have this happen. The damn thing is very, VERY tiny. I un soldered it, took it off and just put a tiny blob of solder over it. Came across this kinda by accident. I was checking everything with a DVM and for the hell of it decided to check for DC on the RCA. When I applied the point of the probe to the RCA outer surface it slid down and made contact with the chassis and grounded the RCA When that happened....viola....nice sounding music!! I spent the next two hours reading up on how to fix till about midnight. Got home this afternoon, did the above repair and it's all working great!!
