*bump* - been a while since I've posted this. I'd like to get this resolved, or, worst-case, to replace the subwoofer unit.

Hello! This is my first time to the Klipsch forums. I saw a lot of great advice / answers in other posts, so I figure I'll give my issue a shot. I have a Klipsch ProMedia 5.1 speaker system (which I adore). About a month and a half ago, my speakers started emitting a soft mid-frequency buzzing sound. When any sound is playing, it drowns the buzzing sound out, so I just ignored it. A few weeks later (about a month ago), my speaker system started emitting a high-pitched whistle / whine through the satellites. The whine is always present at speaker power-on, and initially subsided after a few minutes. However, over the course of the next few weeks, the it began taking longer to subside, until, at this point, it never goes away. It is also louder than the initial hum, to the point where it interferes with any sound that is currently playing. Diagnosis-wise, I have ruled out a few things. Firstly, it has nothing to do with my computer. Plugged into two different computers (via Front/Rear/Center plugs), my phone (via the auxiliary in jack), and nothing at all, the same behavior seems to occur. I've also tried to rule out electrical interference: I've tested it on two independent circuits and the problem still exists. It does, however, only affect the speakers ... neither the subwoofer nor the headphones (in headphone mode) show any sign of the interference. It's only the satellites, and the interference is present on all five of them (seemingly) equally. There is definitely a buzzing noise coming from the circuitry board with the AC/DC converter on it, but I never listened to the board when it was working, so I'm not sure if this is normal. The buzzing seems to be coming from the red coily things (to the left of the AC/DC converter in this picture), but it's hard to pinpoint. I've taken the system apart and I can find nothing obvious ... no blown capacitors or burnt fuses that I can see, at least. I've scanned these boards and tried gently pushing on the BASH chip; it may have affected the humming/whistle a little, but it may also be good ol' placebo. Anyways, any help would be greatly appreciated. I love my ProMedia speakers and thinking that they may be broken makes me truly sad.
