Diagnosed a Bad Flex50 Amp, replaced it with a new one. I am getting “no output-power stage 1” and “no output power stage 2” faults on the main panel. Does this mean the new amp is bad out of the box? When I queue up the amp for the circuits the trouble clears but when I deactivate it the troubles come back. Seems weird to me.
