I have nearly the same problem. I turn the unit on, it goes through it startup, but no sound. If I put it into tuner mode it locks up and doesn't go back to the patch. I have to turn in on and off 10-12 times until I get sound. The volume knob make scratching noises when I move it. I'll probably open mine soon and see if there any issues with the knobs.

I think the master volume is just a simple pot controlling something in analog domain (power amp volume), so cleaning it should help; replacing it should fix the problem.
If you turn the guitar input knob all the way up, can you make the clip light come on when you strum hard? Does it go off when you mute the strings? Have you tried replacing the guitar input jack? Does the Aux input work with the same guitar and cable?
