Jvc hx-d7 sound If I turn the volume knob down to fast the volume turns up. Any ideas?

The contacts in the volume control encoder are dirty. If you know what you're doing, it can be taking apart and cleaned, otherwise replace the volume control.

Emerson Heritage Model # NR303TT getting very low audio from speakers, even with the volume all the up. Any help is apperciated. Thanks!

Sounds like a dirty volume control switch! If you could open the radio and look for the volume control inside, spray some contact cleaner if there is small hole on the metal cover of that volume control, after spraying play(side to side movement) the knob of the switch so that the contact cleaner would spread inside the switch. If that does not help, you should replace the volume controller switch with the same value.
A simple electronic technician could replace it.
Hope that helps you out!
Thanks for asking FixYa!

I have sony LBT-XG900Av. The volume knob wont adjust volume. Even when using remote you cant adjust volume. Its just on loud

I think the problem will be somekind of audio IC that controls volume and other aspects of the sound has failed. Not a job for an amateur to fix as it will almost certainly involve the desoldering and refitting of multi-pin microchip. I would take it to your nearest Sony Service center.

Sound volume knob does't respond

Chances are that it's a digital volume control.

The fact that it turns down again means it's probably fixable.

Open it up (switch it off first), and fetch a soldering iron. Look around for wires that go from the volume control and see if any are loose connections/broken wires etc etc. Solder these again, and it should work.

If you don't fancy this, take it to a hifi shop and they'll fix it for you (there'll probably be a fee involved)

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.

Volume Knob busted

The problom with this is the volume on/off control is of low quality and does go bad. The part was discontinued in 2009 and is no longer avalible

syntoms include: no power on or off , no sound or volume control of any kind

solution: there is only one solution and it is to replace the switch, however because of the small size of the original switch it is very hard to find a suitable replacement.

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.
