PSW-2000 Repairs

CE13 · 10-13-06, 05:24 PM

Hello I have a Psw-2000 sub, I got a good deal on it when I purchaced my KEF 2005 speakers. It was connected to a CyberPower Surge Protector and an HK635 reciever.

It worked fine until today

when all of the sudden it stopped working. The power light goes on but there is no sound or hum when I touch the Line in cable with my fingers.

I was told that this is likely a power amp issue.

Is there any advice or troubleshooting I could do to fix it? I'm open to any information I could get?

If the problem is indeed in the power amp where could I find a replacement and how much is it?

Does anyone happen to know the part number of the power amp?

CE13,

Have you fixed the problem, as I recently encountered the same problem.

I have been using my KEF PSW2000 regularly for the past 3 years. Two days ago, I moved it about 1 ft. to the left of its original location, and it suddenly stopped working. The light on the subwoofer still turns from red to green when I switch on my receiver, but I don't hear any sound from it.

What could be the problem? Any suggestions?

Have you checked for a possible blown fuse?

No, not yet. Do I need to open the box to check for the status of the fuse? Also, if the power light is still on, would it mean the fuse is intact?

I did unplg and re-plug both the power cord and the subwoofer cable, and I touched the subwoofer cable with my finger, but I still heard nothing.

Thanks.

Its that chip you need to replace likely. Although others told me it was the power Amp, it wasn't.
