Yamaha Stagepas 500 startup-protection fix

Unread post by custom_elect »

I have seen problems with the Stagepas 500 going immediately into protection/shutdown when they power up, and this post is what I did to fix this.

Note, this problem is not related to over-driving the amps and the unit going into thermal protection after a while, but this is turning the unit on and it immediately going into shutdown, then when left on for some time power-cycling and working as normal.

These problems were seen doing outdoor, evening, waterside, beach gigs in high humidity.
