Full Answer

You have to disconnect the amplifier from a power source and open it so you can view its internal components. The first thing to inspect is the electrical cord. If it is loose or damaged, replace it. If the electrical cord is in good condition but the amplifier still receives no power, locate the internal fuses and test each of them. If there are any faulty fuses, replace them, and test again.

Test the amplifier again. If these measures don't solve the problem with your amplifier, seek additional assistance from a professional.
