Purchased a Spider IV 150 2x12 and when it arrived and I plugged it in the amp won't boot. The led screen flashes from dim to bright every few seconds and the main effects knob's lights all stay lit. The amp will make no sound. I have tried the factory rest, but I can't even get to reset. It hit a rest screen one time, and I still don't know how I did it, but the thing hung up at 3% for about two hours and nothing ever happened. Does anyone have any ideas? Thanks in advance for any help any of you can provide. James H.
