![]() ![]() I will put em back together and re test em to make sure exactly what is wrong, sorry i didnt do that first, wasnt thinking, was too excited to use my new multimeter lol. 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. In summary, I have not felt the need to change over the years, its power is sufficient to fill an average room even to slightly shake the doors. 1 ok so i have a altec lansing 2.1 computer speaker, and the plug on the subwoofer where the right speaker output is broke on the circuit board.
