Re: Onkyo SKW-591 subwoofer is dead
If the cone is extending and staying out, that is because there is DC voltage keeping it extended, there should be 0 volts across the speaker. The sub does need an input signal to turn it on (unless it has an on switch)
The brrr may be gone because the ic has failed again.
This sub uses a switching power supply so there should not be any 120hz hum coming through the speaker even if a supply cap was weak.
If these are not there, what else is not there? I will guess that if the +/- regulators are not there, where does VAA & VSS come from?

There are no 7805 or 7905 ICs, on the board
