Moved to a new house about 6 months ago, had my synth in the closet and kind of forgot about it for a while. Whipped it out the other day, only to find out that it won't turn on. Any idea what the problem could be? What kind of warranty does the Minibrute have? Pretty sure I've had it for over 2 years. Should I just take it to my local repair store and see what they can do?
