Hi there and welcome to Just Answer. Thanks for asking your question.
To reset a 487, switch off the unit using the POWER button.
Hold in SPEAKER A and SPEAKER B together.
Press POWER while keeping the A and B buttons depressed.
The display should start to flash. When it does, release the A and B buttons.
The unit is now reset.
I will be here if you need more info or have a follow up comment or question.

Ok, I believe that it reset, but still no sound. Any ideas??
Well, it could be many things.
Since you have reset the unit, you now need to go back in and set up everything.
The manual is here: http://www.usa.denon.com/AVR-487-OM-E.pdf
What are you hooking up to it?
Is it the center speaker? That speaker won't normally work for regular stereo sources. Hook something up to the front left or front right and fire up your cable box.
Do you hear anything?
Do you know for sure that the speakers are working?
It sounds like you may have blown them out - you heard a high pitch sound for a few minutes??.
To check this, get a small 9V battery and put it across the speaker wires. The speaker should make a noise.
Can you check that for me?
I know for sure the subwoofer is working because when you unplug it and touch the end it humms at the speaker. The other ones I'll have to try this evening when I get home. I have to work at both of my jobs today so it will be about midnight before I get back home.
When I reset the receiver lastnight, it made it's normal clicking sounds (as it activated during warm-up) and as I switched between TV and Tuner I thought that I heard a faint switch like it was trying to work, but ultimately no sound came out.
Ok, will do. I'll get back to you late tonight and then I'll be online first thing in morning before I go to work.
Thanks for all of your help on this matter!!!
If I hit the accept button now does that end the session? If so, would it be better to wait until we finish this thread? I just want to make sure that I stay on the same page as you since you know what you're talking about.
