Question about Denon DRA-455 Receiver

Denon DRA-555 Memory won't hold set FM stations when powering up

Hello,

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.

Any help would be appreciated.

    I have the same problem with a Kenwood KR-A46. Must be the same amp with a different name on the front panel. Layout is a bit different, but the features are the same. It will remember the stations from time to time, so wondering if it has to do with power shutdown to the memory/keyboard/display IC.

    I first looked for a battery, but none to be found. Any idea what kind of capacitor I would be looking for? I could just try every cap close to the IC :-| Unless someone has a schematic that can identify the exact one.

    You got to fix the problem, if you located the capacitor can you tell me where it was?, Thank you very much and I hope your answer soon.

Try resetting the unit by unplugging the unit from the wall, then plugging it in again WHILST holding the power on/standby button in. This should reset the system. If not:

I have a matsui MCH 750 mini hi-fi,i am having problems with the FM radio channels,sometimes or most of the time i get what seems like the channels are not tuned in properly or the aeriel is not good


If you're sure the FM signal strength at your area is good, the fault is with its AFT [Automatic Fine Tuning] system circuit inside the device. Contact any service technician to get it repaired. This is not a user repairable fault. http://electronicshelponline.blogspot.com/

Some auto stores and Radio Shack have an antennae booster that plugs in between the antennae wire and your radio. It powers from the fuse block.
