Hi Cliff
I am from India, and I own a klipsch 5.1 too. I totally understand how you feel, and beleive me, if the same had happened to me, I would be considering burning myself up under a NASA rocket exhaust or something.
However, since you live in the US (i think), why dont you call the Klipsch ProMedia Customer Service

They will be the best people to guide you on how you can fix your system.
A word of advice. Always connect your electronics through a good spike buster. A good spike buster will go a long way in protecting ur gear. Also, when you are not using the system, switch off the main speaker switch (the one on the rear of the sub). I know its a pain cuz or its inconvenient location, but like they say, better safe than sorry.
Good Luck!!
