What is the problem that it won,t turn off properly? It works fine while it,s on.
SOURCE: Amp wont switch off of stand-by
Both units have a problem with the output section. In case 1, the outputs are likely to be shorted. In case 2, the outputs are open. The low level and distortion come from you driving the speakers with the driver section of the amp. Both units will need to see a service provider.

The voltages are wrong. You should see (0.0, +/-0.6, and B+/B-) on the 3 pins. The driver section has a problem. Check the driver stage for shorted transistors or open resistors.

check your output stage for bad speakers cable or bare wire of cable touch the body of amp----short circuit speaker cable----bad speaker it self------ bad input cable or defective input device .
disconnect all and check if it is ok---start to connect one by one from input to outputs------if all above failed you must contact service center for help.

Solution if all fuses checked out OK and +/-40V are present on main PCB DC connector from power supply:
Check for +37V and -37V on small sub-power supply PCB - mounted vertically on the main power supply PCB. (next to ribbon cable connector is a layout with voltages.) If the +/-37V are missing check (replace) C501 (0.1uF) on the small power supply PCB for leakage, but also check (replace) R401 (2R2) and R402 (2R2) on the main power supply PCB. Both resistors are fuse-resistors and will have gone open circuit when C501 has gone leaky.
