The front end is bad on this reicever. Your going to need special equipment to trouble shoot this problem, as Its all RF. It is most likly not worth repairing as a shop will most likly charge you more then its worth

SOURCE: FM antenna is not providing

If I understand your setup, you've connected the receiver antenna terminal to the output of the antenna amplifier. If this is true, I'd suggest trying the receiver using a plain old FM dipole antenna (available at Radio Shack and other stores) or even just a piece of wire hooked to the antenna terminal. You should be able to pick up some local FM stations then.

What might be happening is that the FM is being filtered out by the amplifier. Some amps made mainly as a TV signal booster have an FM trap designed to block the FM broadcast band. In the analog broadcast days, the FM band was right near the sound part of a TV signal, and the trap was there to prevent interference. It may be filtering out your FM band.It may also be possible that you're just overloading the FM antenna input with the amplified signal. Sometimes a signal can be too strong. Using a simple wire antenna will let you test the receiver by itself.

Other than connecting an antenna you shouldn't have to do any setup for FM reception. If you still get no stations at all when using a simple antenna, then the receiver may need service. But I doubt Circuit City would have sold a floor model that was defective, even at the very end, unless it was clearly marked as such and sold "as-is". I'm pretty sure you'll find that the receiver works with an antenna made for FM.

Display reads "not connect" for v.aux input; how do I reconnect?


I would have thought simply making certain that whatever is connected to your Video Aux connection is actually in the socket and is not hanging out or even a faulty lead.

When on FM tuner, stereo stops playing after a few minutes


Right then sounds like the connection from the aerial lead into the receiver - check out the socket where the aerial plugs into!

Is it loose at all or could there be a bad connection inside the unit.
Get the cover OFF and investigate yourself before you rush down to that very friendly repair man along the street.

it's obviously getting interferance fronm that whole house broadcast unit (not abnormal!) best and only thing you can do is to move the stereo to a place where you can get the MOST am stations the loop ant. is exactly what it says it is a loop of wire with two ends..both ends connect to the ant. input on the back of the unit..however if that whole house broadcast unit is the devil then an ant. no matter what or how it's made will only recieve more static not built to reject static! so you've got to move it unfortunately ..fm is a totally different band obviously fm isn't being affected by that whole home broadcast unit..you're lucky! on that count

Denon receiver (DRA 397) will not speak to iPod dock


IF YOUR NOT USING A DENON IPOD DOCKING STATION IT WILL NOT FUNCTION CORRECTLY.
YOU CAN CONNCET OTHER TYPES OF IPOD DOCKING STATIONS BUT YOU WILL NOT HAVE CONTROL THROUGH THE DENON AND ONLY CONNECT THE AUDIO FOR THAT DOCKING STATION TO THE DENON AS ANOTHER SOURCE INPUT
