Samsung SIR T-451 Issue

[tvrobert]

After losing Voom (bastards) I got a Samsung SIR T-451 for OTA channels. Does anyone know if there's a soft or hard reset for this thing?

Just in the past few days, the audio is only coming out the right side. It happens on all channels. The cables are all in order. Once in a while it "drifts" back to center. I'd like to try to reset the thing somehow before I ship it in to get fixed.

Thanks for your help!
