What useually happens is that when one amplifier goes faulty the sensor detects DC voltage on the faulty channel and switches it into standby and disconnects the loud speakers to save burning the speach coils out and puts the system into "safe mode".
It is not the sort of repair that I can describe how to fix it online. Sorry but it sounds a bit expensive to repair, The output stage is possibly faulty on one channel only.
