Volume Control not working properly

I have an Aiwa cx-na777 which works great except for the volume control knob. No matter what you do, it turns the volume up. At times, if you go real slow to the left, it will decrease in volume, but for the most part the volume only increases with any turn of the dial. Is there anything I can do to fix this problem? Thank you!

SOURCE: volume knob

In other words the lever that the front knob is attached to is broken or the microswitch is bad or broken.. if your not a tech please take the unit in to a shop as there are no user serviceable parts inside these units. Good Luck

SOURCE: I need a part # for the volume controle on an Aiwa

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.

To get to the sound settings: Press and hold the Volume knob down. Press the "Seek" button until you see "Fad" on the display It will be between "Bal" and "LPF" Turn the volume knob to adjust

I have an Aiwa cx-nma545 that I just hooked up to a Westinghouse SK-32h640g. The sound is very muffled. The sound is fine if I have it on cd or the radio but when on Aux Video I can barely here it.


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.

Aiwa Shelf system volume control doesn't work right


The part in question is called an encoder. I have had to replace this part on a number of Aiwa units. If you can post the model number off of the back, I''ll get you the part number.

Volume


the volume control needs to be cleaned. this control is a step switch basicly. and the switch contacts are not making proper contact. cleaning this requires dis-assembly and desoldering so if you are inclined to do this work happy fixing if not it shouldn't cost much to fix.

Volume knob


Normal Aiwa compact shelf units use what is called a jog switch for the volume. Usually you can tell the difference if when you you turn the volume up or down. It goes a short distance and seems to spring back. In this case there are two momentary contact switches. One for up one for down. With a plastic lever on the back of the knob that bumps the approriate switch whether turning down or up. If the lever is broken it will bump up against one but not the other. If it is broken plastic you know how good gluing plastic goes it never seems to hold.
