Hi Your Problem need an expert Technician, this Aiwa stereo has the digital type volume control that gives pulses to the cpu to make volume up / Down. Solution to be fixed by a technician: - Remove the volume from the front board, disassemble it and clean the conductive parts inside it then reassemble back and check. Good Luck Toufic G. Malek

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

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.

You can try contact cleaner. Spray some in (with unit turned OFF) and move the knob up and down several times stop to stop. then try to see if it helped.

My Compact Disc Stereo System NSX-AJ50 is tripping off every time I turn it on. Henry dulcerito@live.com Thanks.


One or more of the output transistors has failed or you have a bad speaker. Try disconnecting both speakers and turning on the unit. If it still shuts down, then the transistors are likely to be defective. These can be replaced for about $15-$25 plus labor at any service shop that handles audio gear.

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.
