My psw550 sub has no sound. I have eliminated the signal source as the problem. When I use a test tone from the receiver, I can hear it in the sub, but barely. Something tells me that the amp inside the sub is malfunctioning. Any ideas?? Is this a repairable item or do I need a whole new sub?

    The model number on the back says it is a psw-550, not 505. I bought it new back in 2001 and it worked fine for several years, but hasn't worked for the last couple of years. I have tried changing the configuration on the receiver (ie large, small, etc) but it doesn't change anything. I then thought maybe the pre amp output went bad. Just bought a new receiver yesterday, but the sub still won't work. Connected via the LFE.

    I have tried all 3 inputs. The power 'on' light is coming on and the fuse inside seems to be intact, but still no sound. Guess I will have to contact customer service. Do you know if the internal amp is a user-serviceable part that I can replace myself?

    No sound out of PSW505. Hooked cd player into back of sub (suggested by Polk Tech Support) and only slight static heard when sub turned to max volume setting. Out of warranty 8 months (bought 05/04/2006) has not worked in 3 or 4 months. I saw other people helped without sending sub in hope someone can help me, work cut hours last year 20%. Back to full time now but catching up. Can I check volts or Ohms to try and determine anything.

    Thanks, Brian
