If the subwoofer has its own power cord seperate from the rest of the audio system, the internal amplifier could be fried or u have a loose connection inside the box

I WOULD LIKE 2 NO IF I CAN RESET MY PASSWORD 4 KLH SURROUND SOUND SYSTEM. I BOUGHT AT A SALE AND THERES NO WAY I CAN FIND OUT PASSWORD. IT IS A KLH SURROUND SOUND SYSTEM DVZ-2500 MODEL # IS 0044224000657.I WOULD ALSO LIKE 2 NO IF AND WHERE I CAN GET A MANUEL....

Well it would void the warrantee, but you can take the back panel off and the power supply will only have two leads (3 if grounded) in from the plug, and out to the crossover. It sounds as if you are correct that the power supply is bad.

Power supply inside has been damaged and is in need of fault dfinding and repair. Take it to a repair shop.

You will just need to re-pair it. That is assuming the new board fixed the issue. https://www.fixya.com/support/r26362721-pairing_bluetooth_devices and also https://www.google.com/search?q=pair+a+wireless+Jamo+360+sub+to+sound+bar ..

It's problem come on due to a fault on the speakers or wiring or connections especially shorts! Clear that and it should come back on. If not then you have a fault in the main power amp section.

The manual doesn’t show a user replaceable fuse are you plugged into a house outlet or a power strip. If power strip confirm that power is present and try another slot to plug into. https://bcc2479de3c817356f4e-1bbe459354cb22c942d9efbc3d6dacbf.ssl.cf2.rackcdn.com/product-manuals/SUB210_OM.pdf

Did you google it. Google, c80 sub woofer schematic, then look at images.

Sorry we are not in the parts business.

You will have to remove the speaker to access the interior of cabinet. Option 2, if you have base tubes or holes in the bottom of cabinet you can try to shake the loose piece out of cabinet, very hard though

Have you tested the speaker?

Hi,I have the Jamo sub 660 and it won't come on,I took it to my technician,and he told me that it has a broken ic,the broblem is that he cannot replace it cause the number on it is scratched,does anyone know what the number is pls! Thanks in advance Joseph

Does any other speakers work through the channels you are putting the subwoofer through? Reason i ask is could there be a fault with the channel you are using i.e AUX? is your subwoofer connected with Aux cables or is it a speaker cable? If aux cable is there a slight break in the cable? Have you checked the subwoofer for any faulty wiring although i would may be discard that idea as if it was faulty it would lose sound altogether. But still may be have a look to cross that off your list you never know. But to me i think you have a faulty channel or Aux connection/speaker connection on your amplifier/stereo.

Possible this is a distortion from the Amplifier if the speakers are not damaged. however it is important to switch the speakers to confirm if the fault is relative to the particular channel in which case the amplifier is faulty. If not the speaker can be the culprit. All what is needed is to reduce the BASS level a bit lower when the volume is increased so as to allow the cross over to work. Also if teh cross- over network is faulty within the speaker the bass can vibrate on the tweeter.
