I have one of these that produces no audio whatsoever. I am not finding anything shorted, none of the outputs are shorted.
However, the output filter gets red hot idling. And Q123 gets hot, and also has discolored the board. it does not appear to be shorted.
One half the output stage gates has a weird drive pulse, the other side appears to be pulled to negative rail.
