You might try calling again and talking to another representative. I had some 4.1's that died after 1.5 years (6 months out of warranty), and I convinced the rep to accept a return without the $50 fee. I did have to pay shipping though. It wouldn't hurt to try.

Indeed, the first course of action was to unplug it and leave it off. Thanks for the advice. What a drag. I think if I get it fixed I'll attach a heat sink and a fan! Funny that it only happens after a year and a half of constant power, and even when they weren't doing anything!

Hello, I've had a set of 4.1 ProMedia speakers for the last year and a half (out of warranty). A few days ago, all four speakers started hissing badly. This occurs even when they aren't hooked up to a source. Putting the speakers in standby has no effect, and the volume of the hiss doesn't change with the volume control -- it is constant. There was no change in any of my hardware configuration. It literally just started happening for no reason. The speakers weren't even playing anything at the time. I noticed in the course of investigating this that the back of the subwoofer box is extremely hot. I know it runs warm normally, but I can't keep my hand on it for more than a few seconds. When I unplug the unit and let it cool down and then plug it back in, the hissing is gone. But it slowly comes back (getting louder and louder) within a minute. I talked to Klipsch technical support and they want me to send it the unit back for a $50 repair. Not to mention shipping. And what's worse, there's only a 90-day guarantee on the work. Who's to say it won't happen again in a year? I'd be more tempted to spend $150 and get a new set of speakers by some other manufacturer. It's extremely annoying that aompanies these days include such a short warranty on their products. Essentially this says you're buying an unreliable piece of crap. But I digress. Has anyone else seen this problem? Any suggestions? Thanks in advance.
