I have the Polk Audio magnifi max with subwoofer.

It gives a heavy popping sound periodically , especially when nothing is connected but the power. I constantly have to unplug it whenever I am not using it. Recently it stopped completely. I check and realised power was reaching the circuit, however, the led doesn't comes on and I don't get any sound at all from it. I figured its the main circuit board. Do you know I can have this replaced?
