Question about Infinity BU-120 Subwoofer
Power light is on. Will turn on and off. No sound at all
Start by checking for a blown fuse. Sometimes the fuse holder is on the back panel.

I suspect that whatever semiconductor does all the amplifaction has departed this life. If you check the PC board it might point to a burnt out part or a blown one. If not look at anything big or with a heatsink on it.
