Does anyone happen to know how to unlock the protection circuit on the Yamaha WXA 50 amp? Mine has locked up presumably because of overheating on a couple of occasions, have not been able to find out how to reset it, not even in the Service manual. I can still run self-diagnostics via browser interface but the thing turns itself off within 3 seconds. Cheers.
