Alpine CM5908: RR no sound

[boomer]

I have an Alpine CM5908 and all the channels work with the exception of the right rear.
Anyone have an insight into this problem?

Start tracing the wires from your head unit to your speaker, no other way really.

Unless the rear right isn't plugged in....

Thanks for responding. I'm bench testing the unit at home and I feel the problem is within the radio.
I have spare radios and could probably just replace the defective part.

ahhhh well thats a different story.

Id start by pulling the casing off and looking for components that look like the smoke has been let out of them.

I have successfully repaird electronics in the past by desoldering and re-soldering components on the board. Just trace the tracks around the circuit board and see what you can find. It might even be a dry solder joint somewhere on the board, that is worth checking also.

I was thinking something similar, thanks bud.
