No power to my crate monitor amp

[markyt77]

I have a crate apm-75 monitor and i have no power to the amp.I had a friend who was borrowing it and i brought it home and nothing...It worked a couple of days a ago but we did have alot of rain the night before i picked it up.It may have got some moisture in it.I took the front panel off to test the switch and fuse were getting power.no lights come on, not sure what to do any advice would be appreciated thx...
