I'm a total noob at electronics and i was wondering if anyone here could point me in the right direction. I have friends who are much better at electronics, and if i could just point them in the right direction, they may be able to fix it.

I have a Legion Sound (i think it's a bit of a no-namer) 100 watt or so solid state head. I bought the cab off of a friend, and he threw in the head for free. It doesn't turn on, or make any noise at all.

I also have a Fender Stage 185 that's shorting out, I believe. It would sometimes short out, and then recently all sound stopped going through.

Any ideas on how to find or fix these problems would be greatly appreciated!
