My volume control on my Aiwa surround sound system no longer responds to my remote controller. Everything else works fine using the controller

Question edited for clarity.
Question moved from Washing Machines category.

Check out the video. It may just need cleaning with switch cleaner and a couple of drop of sewing machine oil. The fact it does move is a good sign.

did you ever figure out the solution I have the same problem

On most TV's with speaker control there's a way to disable the TV's volume control effect on the level fed out to an external amplifier. Find it and disable it it or select FIXED for its level, or, while listening through the Aiwa, raise the TV's volume through its own remote and see if that affects what the Aiwa gets for volume.

Or, enable the TV's speakers but find the same interna lAudio setting and make it Fixed, but turn the TV volume down if you don't want to hear its speakers. That way, you could actually listen to the TV on its own speakers if you want, say, for casual watching of the Weather Channel or news, for example.

Required Aiwa remote is available in Part Store for $39
Thanks.

The "volume control" on your Aiwa is in fact what is called an "encoder". These can fail. They work in concert with the microprocessor to control the electronic volume control IC. Yes this part can be replaced. Try calling Sony with your model number and request the part number for the volume encoder. They should be able to help.

The system comes with l remote which provides controls for "Power", "Master Volume", "Bass (Subwoofer) Volume" and "Matrix Mode" . Matrix mode allows you to spread stereo sound to all speakers where your sound card may not have the ability to do so.
I find that the "Stereo Surround" setting works best as opposed to the recommended "CMSS" setting

batteries?

Unplugging my TV for 15 seconds (longer actually - at least a minute) made the remote and the satellite TV remote both work again with the TV.  Thanks for the tip!
