Wire shorting out - on tanning bed!

Okay, this is a bit off the trail in requests, but I do need help!

I bought a used tanning bed from a salon that was going out of business back in February. About mid-summer it started shorting out -- you can turn it on but it would click off minutes later.

I know nothing about electrical or tanning bed repairs and don't know where to go to get this fixed. Does anyone have suggestions? I'd like someone with electrical experience to come take a look. Willing to pay someone to fix this but can't afford the big bucks of a tanning bed customer service call or handy man fees.

Any suggestions?
