every time I replace the fuse and turn it on from OFF I get a muffled sound from the speaker but no light on the front bottom little logo. Moved the unit a month ago and just plugged it back in to demo for a sale. Sub purchased in 2001 and never had a problem. Any body have any suggestion what to do next or what the problem Could be...... Klipsch says to return for service but I'm not doing that..... thanks
