REV1 no sound on right deck

I am getting no sound on the right deck. Originally the right deck vinyl mode sensitivity was not engaging when I was scratching, now scratch mode appears to work (according to the wave forms on serato) but no sound at all.

I plugged in my Rev7 and S11 mixer and have no issues with right side, when I got back to the Rev1, no sound at all. Any idea how to fix this? I've tried all audio settings on Serato with no luck.
