I have DENON amplifier PMA-980R It does a strange thing. The input selector button(CD, Tuner,AUX, Data etc) jumps like crazy from one selection to another and I have to turn it of. It does it randomly and sometimes stops, sometimes won't work for days.I can't found any pattern as when it does it. Can you , please help, as it is a fantastic amp and I really want it fixed. Thanks Vesna

I have a Denon 980 with the same problem.
I do suspect the selector switch ( no buttons).
Because it happens ( sometimes )also with the switch from the speakers ( A+B ). And i could reproduce it when touching the knob of the switch.
So now i'm looking for some new switches.

Greetings Casje

I have the same problem. The selector buttons is controlling a bunch of relays, and as both the input and the speaker selector button are acting strange, I suspect the problem lies within these relays.
I have tried cleaning the selectors buttons, but with no luck.

So I'm interested in a solution too :-)

We have a DENON L.C twin transformer amplifier PMA-735R that has an input selector that freaks out now and again. Recently it has gotten worse, it just goes back and forth between tuner and cd etc. for...


Hi Readers to of Fixya,
This entry is January 22, 2016.
I own a Denon PMA 735R which I bought new in 1999, it is very good Amp; starting about a few years ago the input selector would occasionally randomly jump from CD to Phono to Tape etc., but would always end up back at CD so it was not terribly annoying until a few days ago when it started happening all the time. I am a very knowledgeable electronics person (I built musical keyboards at one time) so my thought was just that it was a dust problem and I started with that premise. I fixed it using an Electrical Parts Cleaner spray and here is how I did it:
I unplugged it, removed the CD input RCA cables and removed the L & R speaker cables and took it off its shelf and set it on a towel on my soft sofa; I removed the casing by unscrewing four big silver screws on the sides (my model is silver) and the three small black screws on the back top; I removed the Input Selector indicator knob on the front and the Record Out Selector indicator knob and the Volume knob, I then removed the small nut that holds the three of them tightly in place to the front panel; I then stood it on its back so that the front was facing up; I then sprayed my Electrical Parts Cleaner spray into the Input Selector indicator post liberally and then put the knob back in place and kept turning the indicator back and forth for a few minutes to work the cleaner inside the post down into the circuit board connection; I did the same with the Record Out Selector indicator post and I did the same with the Volume post; I then put the small nuts back on the three posts and tightened them; I then put the knobs back on the three posts; I then stood it back on its normal upright position and put the casing back on and then the screws; I placed back on its shelf and hooked up the cables and switched it back on and played my CD's, it has been working perfectly fine. The whole process took less than 30 minutes.I hope this helps.

Why can't I get my turntable to sound right on my


Turn table? You mean like records? lol
The output of record players is different voltage than like cd players, etc...
Does your stereo have input for turntable or are you hooking it up to an extra rca input? I had mine hooked up wrong before and it did same thing.

Hi, i have a Denon PMA 735 R amplifier which shuts down when volume increases suddenly.


Sounds like you have output transistor problems. Does it have a red protection light that comes on when it shuts down? If it does it will need serviced.

Problem with the Denon PMA 6.5 amplifier. The source selector keeps on switching between the CD and AUX inputs randomly on its own. Any idea what could be the problem?


bring a good contact cleaner from radio shack near you and apply spray with pipe in the selector and move it forward and backward.

The source selector just starts changing input sources all by itself. Then once started it might just keeping going for minutes. Is there a way to prevent this from happening?


try to apply a spray(contact cleaner) with long pipe to the selector and move it many times(you can get the contact cleaner from radio shack near you.

DENON Input selector jumps randomly


I have a PMA-535R. Same problem but slightly different dialknob. I fixed it by spraying a contactspray and WD-40 into the knob itself. This does mean you have to disassemble the front of the amp and take out print of the dialknob. The knob has a plastic dustcovere that you will have to lift. Good luck
