Onkyo Integra A-809 input selector switching by itself

Hi, My Onkyo integra A-809's input selector will start randomly switching between input selections. Sometimes it does it very rapidly, and sometimes it works just fine. I'm thinking it must have to do with some interference with the infrared sensor but am not sure. I tried covering the infrared window on the front of the amp but that doesn't work. Any ideas? Should I open up the amp and try and cover or shield the sensor directly? I don't ever use the remote so it wouldn't matter if the sensor was completely blocked.

    Yes, I have had the same problems for several years. I would love to have a fix.

    How did you get Onkyo to respond regarding this bug and the workaround. I tried emailing their support and never got a response. I took the tip from Siliconchip and did some poking around making sure everything was connected inside and that helped - I went weeks without a problem then it started again. I then grabbed the selector knob and worked it back and forth in multiple directions (not rotating it through its selections but really rocking it back and forth) Once I did this a few months ago I haven't had the problem - it started switching once and I did the rocking thing again and no problems. It must have something to do with the inner connections in the switch. Maybe the contacts somehow got corroded or gummed up. I'm reasonably happy with it now as I have a solution that is simple and keeps it working.

I'm going to assume that your input selector knob just turns and turns, with no stop. Correct? If that the case, you have what's called a Rotary Encoder, which is most likely bad; the very kind of Encoder is used for your volume control. This is not something you can easily fix. It provides inputs to your display microprocessor IC(one of the computers in your unit) It can also be the microprocessor IC, and an input switching control IC. Neither are DIY repairs. If you'd like more information, or would like inquire about repairing your unit, please visit my website at You may contact me there. Thank you.

Onkyo knows about this bug and has a rather expensive workaround available.

    I took the amp to a service shop in Portland, Oregon called
    Innersound. I don't know how they got Onkyo to respond and I'm not
    sure what they did to fix the problem. They said they were talking to
    Onkyo. They charged me $150. It works now - I can occasionally hear
    the original thing going nuts in there, but it doesn't affect the
    source selection. Go figure. Sorry, not a very technical reply. :~)

This is not an IR problem. Could be just loose connectors and dry joints. You'll need to open the unit and visual inspection of the PCB and connector for abnormality.

Good luck.

    Hello Mcraiga,

    If all connector had been check inside for lose connection, could be
    a dry solder joint in any of the connectors too...creating intermittent
    contact rendering the input selector to play up. Another thing is the input selector
    of your unit. Aside from the remote, is there any rotary selector at the front panel,
    sort of an encoder rotary...if there is, it might needs servicing...grease inside might
    gummed up.

    Good Luck.

Integra DPS 8.5

The Integra DPC-8.5 changer (as opposed to the DPS-8.3 single-play unit -- not sure which you have, as you mention DPS-8.5, a non-existent model) and most of the integra line of players, will sometimes be thrown into brainlock by out-of-step shutoffs. They will usually respond to the Integra/Onkyo instruction manual's directions to turn it off (you're already done that), then unplug the power cord from the back of the machine, wait a few seconds (make it 30 to be safe), then plug it back in and turn it on via the standby switch. The screen should display its welcome message, cycle through startup, and being working again. It is very much like rebooting a PC. In fact there is little difference.

If this doesn't work then something has gone wrong inside and probably has nothing to do with your shutdown method on the way out the door. These things do happen. Hopefully by now you've already figured this out. If not, give it a try. It usually works.
