Remote for home receiver acting strangely

(1/2) > >>

fixit7:
My remote or maybe it's the receiver(Denon 1801 AVR), but

sometimes it turns on the radio and changes the volume ok,

or else I have to get within 2 feet for it to work.

The batteries for the remote are are at the proper voltage.

The keypad and the circuit board have been cleaned.

The only thing that has changed in the last month has been the addition of a dipole antenna to pull in stations for the FM radio part.

But it is an unpowered antenna.

Anything else I can check?

Thanks,

Electrolytic capacitor(s) in the remote may be degraded. Check or just replace. IR led is next in the list to check/replace. Less likely problem - degraded electrolytic capacitors in the receiver 5v supply of IR receiver

Or  maybe the rubber keypad keys even if they are cleaned may have lost its contact properties ...

you have things like this :

Does it stop working properly when you turn ON lights in the room?

It works ok when 3 CFLs are on. They are within 8 -> 12 feet of the radio.

Now it is working ok.

Not sure what it is called, but when the radio is turned on or off, I hear a clicking sound.

Maybe some kind of relay?

I am happy that the radio works ok, even if it is occasionally cattywonkus. :-)
