Canon MVX150i DV-Camcorder won't power on!

I went filming today - using my mates camcorder. We got caught in the rain - shielded the camcorder from water. Once sheltered, I checked the camcorder to see if it was alright. It had a few drops of water on it’s outside, and it was still working: able to power on and work. But when I got home, I tried to power it on and it won’t! I’ve tried plugging it into the mains and still nothing.

Is there anything I can’t do? (apart from buy a new one) Does anyone have any idea what is wrong with it?

Please help thank you.
