Boss NS-2 not turning on?

[Nova]

Hey guys!

I bought a Boss NS-2 about 3 months ago for around $35. It was a little beat when I got it, but the dude sent me a demo of it, and because I was in a hurry, like a dumbass, I trusted it. I left it at home with my gigging rig while I went off to school. When I came back, it wouldn't turn on. I'm using an MXR Power brick to run it, also tried a new 9v. Neither of them will turn it on.

I used compressed air and some electronic cleaner stuff I got at Guitar Center in the input jack, but still nada. I even opened it up to see if there were any loose wires or anything, but the way it's built, the circuit board covers them, and I'm nervous about trying to take that out (if you even can). Do you guys have any ideas? Or am I out $35?
