PSW110 Issues: Static , Heart Beat woes

My PSW 110 (Out of Warranty) recently started to make a pulsating noise. I have swapped the power cable and tried it on a isolated circuit in the house. Also input cables have been swapped and tested. The sub will do this without any input from the receiver. The only way to silence the sub is to remove the power cable. Any thoughts? Is the internal amp faulty? Seems I'm not the only one :-(

Do you have any info to back up the "good service record" claim? I'm hesitant to invest another dime in Polk audio.
Upon further research I can find at least 40+ instances on the web of my exact issue. Amazon, Crutchfield, AVS Forum, Tomsguide, Polk forums ect. The Amp unit in these sub's (and other models with this Amp assembly) should have been recalled.
Welcome to Polk's forum, sorry you're having a problem. The best approach is to contact Polk's CS department at: 1-800-377-7655 select option 1. Have the sub's serial number and date and place of purchase handy when you call. They'll take care of you.

Thanks a bunch Ken.
I called the # and talked to a cs tech named Mike. I would advise everyone to avoid this guy. He was the rudest cs guy I have ever dealt with. He started shouting at me so loud that my wife came into my office to see what the heck was going on.
He said EVERY subwoofer brand makes that heartbeat sound.
I finally asked to speak to his supervisor and he asks "WHY".
I talked to his supervisor named Kim. What a complete turn around!
Kim was a VERY pleasant gentleman to talk to. He knew the heartbeat was an issue, asked where and when it was purchased and asked for serial #.
He then said he would ship a new amp to my house, gave me a confirmation # and said he would email me when shipped.
My faith is restored in Polk Audio .
I'm certainly sorry there was that kind of situation, but glad Kim was able to help. I'll forward this to the appropriate person, Chet. Again, sorry it had to happen that way.
Best regards, Ken
Iam not sure if I have posted in wrong section.

The bass amplifier needs to be repaired or replaced. Assuming you live in the U.S. you would contact Polk at: 1-800-377-7655 select option 1. It would be helpful to have the unit's serial number and date and place of purchase handy when you call. If you live outside of the U.S.send an email to: [email protected]
Send an email to their Canadian manager, Walter Moser, at: [email protected] he will be able to help.
I'll ask a friend at Polk to contact you via email.
If that's the case I would just save up for a new subwoofer(Svs).

Could you possibly expand on the steps you used to do this? I am also having this problem with my psw111.
I too would like to know more about your fix.
I am especially interested in this bit, since I was able to find how to replace the capacitors elsewhere.
EthanC: Hello. I also have the PSW111 and it started humming a few months ago. This happens with no inputs and in all power outlets. Are you able to assist?
Thank you,
Don
EthanC or Donkmoore or anyone - do you have the detailed instructions on how to fix?
Thanks for any help
