Circuitry protection
There is no reset, Sometimes if you hit them on the top or sides with your fist, They will start working again.

you should have a orenge moniter or audio out tha goes from you yamh to the amp
SOURCE: DC Offsets on output - protection don't allowd to switch on
you don't want to do this( bypass the protection0
that d.c. output will burn the coils in your speakers with out making a sound!! you have a biasing problem
or like you said a d.c. offset problem it is best to work on this problem with out a load on the amp, this will allow you to trace back where the trouble is starting at. caps will cause this sort of problem but leaky transistors can also do this, even diodes.
this will require an experienced trouble-shooter.

Start with the process of elimination...disconnect speaker wires and (obviously) speakers. Does the amp still enter the protection mode? If not then check wires and speakers for issues. If the results are unchanged, look for protection circuit problems or "overlooked" power supply issues. Good luck...
