I am currently a college student living in the dorms on campus. Last year, I purchased the Klipsch Promedia 2.1 speaker system (http://www.klipsch.com/products/details/promedia-2-1.aspx) and absolutely LOVE them. Couldn't ask for a better buy, and I'm glad I splurged a little to get a quality speaker set when I look back on the decision.
However, I've had a consistent problem as of recent (last few weeks, basically since I moved back into the dorms from home) where my right channel will quite often lose signal, which can be remedied by simply tapping my foot on the sub unit which is next to my feet. I did a little experimenting on my own and found that when I plug the right speaker into the left input on the sub unit, everything works smoothly and there is no loss of signal, leading me to believe that it's a problem in the sub unit connections. When I contacted their customer support services, I was told that it is most likely a problem with the DIN cable running from the speaker into the sub unit causing the loss of sound, but when looking at things myself, I can't see any of the connections in the cable out of place or missing. Klipsch tech support suggested just replacing the part for $20 (http://www.klipsch.com/products/details/promedia-2-1-control-pod.aspx), but being a college student, I am somewhat strapped for cash and would rather not shell out the money for the product, and then the shipping charges on top of that, without being sure that this could remedy the problem. Additionally, should this not solve things, I wouldn't want to go through the hassle of mailing it back to Klipsch (this replacement is only available through their online store).
I was tempted to open the back of the sub unit up and see if maybe the right channel connections had come loose, but I'll be honest and say they have an intricate schematic of screws and other small parts I would have to get through in order to actually open the unit, hence I'd rather avoid this if at all possible.
ANY help or advice you can give me, even if it includes actually shelling out the money to replace the part, would be greatly appreciated.
