I got a Peavey Vypyr amp for Christmas, and lately when I try to turn it on, it turns on, but only a couple of the lights are lit and audio doesn't come out. I'll have to turn it off and on, multiple times, until it'll work. Does anybody else with the same guitar amp have problems? It's the 15W one, by the way. Also, it did partially fall over once. It landed on something, that was maybe 8 inches above the ground and it didn't slam into it, or anything, so I don't think that'd cause a problem. Since it's pretty much a digital amp, is it some kind of malfunction within it's programming stuff, or what?
