The power supply is working but it is possible that there is no supply to the SUB WOOFER amplifier. It is important to remove and open the unit to probe and confirm.
It can be failure of the inline fusible due to a faulty output driver.
Finally check the subwoofer using a AA cell.

No I cant get my sub woffer to work woofer.There is power to the unit .I am trying to connest it to a sound bar which has a sub out.


If there is power to the woofer then a signal input must power the woofer to work. So feed a test signal or a audio siignal from a DVD and if there is no output then the AMPLIFIER section had faults.
Unless the sealed unit is opened it cannot be tested to confirm if the output , the input to the AMP or the power supply has failed.
Check if there is power to the output section to confirm.

Keeps blowing fuses x4 as soon as powered on


Pull the speaker and check the coil with a meter. Should read 8ohms. chances are you have a burnt voice coil. They have a 2 year warranty on subs.

I have power but no sound. I have hooked up another sub and it works fine.


Lack of sound as you have confirmed, lies in the sub. the sub is faulty. check the sound I.C in the Sub and the output side If and only if you are a quarlified technician. Else, a technician needs to help change the output I.C and check the transistors likewise.

PS8 Subwoofer started buzzing non-stop


with nothing connected and the sub turned on....Most subs buzz when the circuitry starts to fatigue. The last time I heard this ..the repair ended up being one of the two fat capacitors inside the sub. I have a means of testing this,,you may not. I am a repair shop with a bit of experience in component level board repair.

I have the same problem as described by Fufanuer. I have no power to S12 Subwoofer as it keeps blewing fuses. As I replace the fuse 4a 250V with new one it blew right away. Can anyone help? Hal


I too am looking for the solution, I'm hoping I have the wrong power cord which is sending too much power to the sub, my next attempt will be to just up the AMP on the fuse b.c hey it's broken anyway
