Last week when I returned home had no sound on my computer , not good since I love Windows Media Center where I record to my hard drive and watch at later date. I looked on my Dell Acct online and this system was bought a while back with my computer . Will be 12 years old in Jan I checked my sound card in Device manager and it said working , Then checked Plugs , cord and connections . I called Klipsch and the tech guy said there was a 5 amp slow blow fuse in the Bass Booster and he told me check that , even gave me a Radio Shack part num. It was blown . Easy right? Wrong. As soon as I powered unit with new fuse it shot rather quickly . Anybody got any ideas what to do next? Thanks .. This is my system , may have to copy and paste
