Denon DRA-555 Memory won't hold set FM stations when powering up
I have had this Denon Receiver since 1986 and it has been a good unit. I am still using it, however I am currently having a problem withe pre-set FM/AM stations. If I program the stations in and then shut the unit down, the next time I power up it does not keep these in memory. I would think this would be a simple fix, but not sure how to proceed. Would this be some sort of fuse? Again, every time the unit powers up for FM it is at 87.7.

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
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.
OK,this is a fairly common problem with digital tuners, I get them from time to time in my shop, you see, what is happening is the voltage that's used to tune the set, usual;y stays rock solid, your device however is drifting off station due to this voltage changing, usually it is in the powers supply or the actual tuner itself. It can be bad capacitors, bad IC's, bad transistors, bad tuner module. Sometimes it maybe a "Dry Joint" too.
The only fix is either a replacement PSU or Tuner or indeed maybe both? One simply cannot tell exactly without examining the unit.
You need to take this unit into a Denon repair center and ask for a "Quote" as to costings etc. Once appraised of that one can proceed from there?
Contact a Denon head or local office and ask them there, for a referral to an authorised service center.
I REMOVED THE AM LOOP ANTENNA. AND THE UNIT WORKED. TO MAKE SURE THIS WAS THE PROBLEM I REMOVED AND REPLACED IT SEVERAL TIMES. EACH TIME IT WENT OFF AND. I THEN PUT ON THE FM INDOOR (WIRE) ANTENNA. THE UNIT BEGAN TO PLAY BEFORE EVEN BEFORE I CONNECTED IT. JUST GETTING IT CLOSE TO THE FM COAX. MADE IT WORK.
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
