Friends I bought an OSP 502 electronic drum set several weeks ago, and now whenever I power the drum brain on, it immediately shuts itself off. I know the set works otherwise because if I hit a pad during that 1-2 second time frame, sound comes through. The set is designed to use a 9 volt DC adapter, but it has had a 12 volt AC adapter plugged into it for possibly as much as a year or 2. So can anyone tell me that it have overloaded and burned out a circuit in the brain? Or i have to buy new one?
