My MV-Jr worked last week... but yesterday and today it won't start up. The control comes on, but the servo packs won't fire up. I get errors for all 3: 391, 392, 393 SERVO ALARM. My control is a Yasnac MX3. If there's a good repair guy on the east coast, I'd be happy to consider paying for a call. Otherwise, if you don't mind helping out, I can do this myself.
