How to fix a TMX wheel that suffered a power surge

So I recently got this steering wheel off of ebay I can't send it back and what I think happened was I didn't have it plugged into a surge protector then our power went out then on then out then on like that. Now It doesn't work. It turns on for a few minutes then turns off then a few minutes later it turns on again it repeats like that I am keeping it unplugged until I can fix it.
