If this were a few years back, I would have tossed the system and bought a newer, better toy. However, after two kids, I'm broke.
I have a Dennon AVR 487 5.1 system from some years back. It has done well ver the years, but a few weeks ago it stopped responding. The subwoofer will not 'wake'. I'd like to fix it, before accepting that I will need to live without a subwoofer.
I think I've tried everything but the red light stays on and never goes green - checked fuse on outside of woofer (I wonder if there is an internal fuse to the amp???), tried different RCA cables, tried every different setting possible, including crossover settings, etc..., reset the Dennon receiver, plugged the RCA cable into different ports on receiver (tape, DVD, etc...), switched speakers to small and large, and nothing works.
Unfortunately I don't have another receiver or woofer to cross test to see if its the receiver or woofer, but the other speakers are working fine. Unplugged it for a few minutes - nothing!
The thing just seems dead. I ran my fingers across the RCA cable from the receiver to see if I could at least get a thump or scratch - nothing!!!!!!
I can't afford a different system or subwoofer - wife and pocketbook both say NO.
Does anyone know if there is an internal fuse for the amp? Any other ideas? Thanks in advance.
