Hi, I've got an intermittent problem with my PSW2010 sub not working. I've read that others have had the sub fail, and it was fixed by replacing a fault board, but in all cases, it seems that the sub just stopped, and didn't start again. I was wondering whether anyone had experienced this behaviour intermittently, and if so, was it fixed in the same way. The problem is that there was no output from the sub. The green light was on (so it's getting a signal), input level is turned up, but there was absolutely no movement in the speaker. I fiddled with all the buttons for an hour or two, tried various CDs, DVDs, turned it off, then on again, etc but couldn't get it working. I also noticed that there was no relay 'click' when I turned it on. A couple of days later I turned it on again, and it worked fine. And then two days ago, put a CD on, and the sub again had no output (but green light on). More fiddling, but still no output. Left it alone and went to bed. I got home yesteday, switched everything on, and there's the sub pumping out it's bass. The only other noteworthy event is that a few weeks ago, I thought I heard it give a 'pop', but it was still working fine, so I put it down to my imagination. I was planning to take it back for repair this weekend, but with it working OK, it's a bit difficult to reproduce the fault. Thanks, Balders.
