My klipsch promedia 2.1 wired no longer powers. I can hear what I think is the relay click and I get a humming from the subwoofer, but no power at the controller pod. Visually I don’t see anything wrong with the controller’s board. Sub’s insides — im not sure as I’m just not very knowledgeable and there was a lot of compound on the internal parts.one board looks burnt in color, but no idea if that’s a problem or not... The din cable To the controller I think looks ok, but could that be the problem? Do the sounds I hear indicate it’s powering okay with the sub and it may be the cable to the controller that’s not working? Thanks
