Noisey Output on Roland XV 3080

[mpeddle]

Hey everyone,

I've got an XV3080 that was working fine a couple of weeks ago, but suddenly began making a sort of rumbling-ocean noise in the background from the main output. It does not increase/decrease in output if I change the volume of the device. It is also present when I listen through the headphone jack.

However, if I switch to the "B" or "C" pair of outputs, the noise goes away. Any ideas what's going on? I would just use the "B" or "C" output, but the workflow is ****ing godawful. I have to change EVERY SINGLE PATCH one by one to play from that output. It makes auditioning sounds horrendously annoying.

Ideas?

I don't have a schematic, and don't know if it uses chips or discrete components for the output amps. Use a multimeter to check the integrity of any capicitors and transitors in the output stage. If they are op amps, swap them out.
