Hello, everybody. My subwoofer won't turn on anymore. I checked the fuse. I opened it up and checked every resistors and capacitors on the power board and even the MOSFETs. None of them are blown. I checked the amplifier board but none of the resistors and capacitors are blown too. Can the IC driver of the MOSFETs be blown without destroying the MOSFETs? Any hints would be much appreciated to fix this sub.

Check the power supply voltages. Are they present and correct?
How did you check the components?
