How could I test that, and is there anyway to test the CMOS chips on the PCB, and test the other items i circled on the first picture.

Looks like there is a transformer or something mounted inside the box of the subwoofer. The subwoofer plugs in to a 120v outlet (USA here). There is no burning or anything on the PCB, Im not sure how to test the audio connectors, 1 is a 7 pin Din plug, kinda looks like a ps/2 port, and then 2 normal audio jacks. Ok its been a long time since i plugged em in, like 7 years, they quit working, i believe they no longer turned on (if i remember the power know and the red LED didnt light up) I took apart the subwoofer box that houses the PCB, i tested most of the resistors and capacitors on the PCB and the zener diodes they all seemed fine.
