Hiya, start by checking the power cable, then check the fuse in the unit on the pcb. If blown, replace and if it blows again then problem could be either Power supply or the amp outputs. If it doesnt blow, stays on but no sound, problem also likely to be output stage. You will need someone with experience to check outputs, etc and a meter though. Hope that helps a bit.
Best of luck

First thing I would do is check C6 to see if it is bulge or blown - regardless replace it with a 10ufd 100volt Non-polarity capacitor. If the fuse blows again unplug the blue wires from the transformer and plug in unit to an outlet. If fuse does not blow then problem is on PC board. I have a service manual for this item. Probable causes on PC board are Filter Caps, Bridge rectifier (DBA), Amplifier module, or fragments of C6 even causing shorts on board if it had blown.
I have bought C6 from MCM Electronics for under .50 cents but you have to put shrink tube on one lead and bend it back along the body and solder both leads in the board.
