system is just over 4 years old. Tried to play a dvd over the weekend and noticed the sub and center not working. Other surround speakers all work. Switched the wire from surround speaker to center, and center worked.
Checked all connections and seemed fine. Checked the sub fuse - fine. Reset the preamp by pressing three buttons. Unplugged the amp/sub and replugged after 15 minutes. Nothing seems to work.
I recently hooked up Sirrius satellite radio in the DSS input slot of preamp, in case it matters.
Is the amp/sub dead? What are my options?
