Kenwood KA 995 amp. volume control, as you increase or decrease the sound, a loud clicking sound is heard.


Katrina, this sounds like a dirty potentiometer (volume control knob). Try turning the unit off, and exercising the knob. That means turn it full turns, many times, like 70 times. Then try it again with power. Sometimes this helps.

My Sanyo FXCD 1100 car radio isn't functioning correctly. When I try to turn my music down, the volume goes up. It also gets stuck in the same volume range then gradually goes up when I'm turning the...


Could be a worn electronic ribbon between the unit and face. They wear from constantly moving and the wires inside break and short out. This happens a lot of movable face stereos. Older head units do not really have a reset aside from unplugging them and plugging them back in. You might be able to find a small hole behind the face containing a reset if there is one, just insert a small pin into the hole to press the reset if so.

Why does the volume increase when I'm trying to turn it down on my AIWA receiver?


Your volume control is bad. If you are good at this kind of stuff, you can remove it from the board, open it up and clean the contacts. Otherwise you need to get it replaced.

VOLUME CONTROL PROBLEM.


If the volume control can be turned continuously in either direction (no stopping), then the control is what is called an encoder and the behavior you are describing is an internal logic failure. If the control has an upper and lower limit (only turns so far), then it is a standard volume control and is physically broken and needs to be replaced. In either case, the unit should be under warranty. Return it to Best Buy for repair. Given that it just came out of the box, talk to a manager and request an exchange.

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


Hi,
This sounds like a case of a dirty/defective rotary encoder. The volume control used here is not the conventional potentiometer type , but a rotary set of switches that tell the sytem if the knob is being turned left ot right.
Do you think you'd be able to open the unit and spray some contact cleaner into the rotary encoder? It might involve dis-assembling it down to front bezel removal.

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.
