Volume knob problem

I've had these vs2121 for maybe a couple of years now and all of the sudden I noticed that whenever I touch the volume knob, the speakers will like crackle or shut off or one you can barely hear and the other is fine. I think it's a problem with some wire connections inside the speakers themselves. Like the potentiometer or what ever it uses to control the volume has worn out. Does anyone know how to fix the speakers? (there out of warrenty)

    I bought these speakers to have at work, and while they sound good, I have to keep the volume control almost all the way up to get sound out of both speakers. I want to take them apart and try spraying some DeoxIT into the volume pot. Someone here said to check for cold solder joints, so I will do that too while I'm at it. If the problem continues, I'll just bring in a boombox with line inputs to use for my work computer speakers. Not getting the speaker apart will be difficult at best.

This is a problem with poor cold soldering at the bootom of the volume pot, what has to be done is slowly seperate the glued seem where both speaker halfs are "glued"LOl... yes glued together,...Use a small flat head screw driver of any sort and work the way around it and it will seperatel and then resolder the volume pots circuit board pins, then use ABS to glue it back together, dont foregt to get the blue LED power light indicator set right before pressing both sides together....

I'm having the exact same problem right now. I find that if I push the volume knob in as hard as I can that seems to fix the problem temporarily.

I'm thinking about turning the volume up about midway and never touching it again, just using the software volume control on the computer to control my audio from now on.

Wotcha, i've just taken amp out of storage, has'nt been used for a while cant get volume to work properly the sound goes from speaker to speaker and up and down in volume whilst crackeling a lot as...

One way of proving it ISN'T the amp circuitry is to remove the pre-main jumpers and jack in a source that has its own volume control (or try a CD that starts really low) because this bypasses ALL the amps controls. If it sounds ok (albeit LOUD) I'd suspect oxidized contacts on the controls. Turn it off and vigorously operate all controls a zillion times to wear through it. In mosty cases it's the unused controls that fail because they never get wiped. Maybe a shot of contact cleaner on those you can access.

Sound cuts off, but if I touch the master volume contorl knob it comes on for a short time. Do I need a new knob, or something else?

Possible that there is fault in the preamp analogue/logic control. When you touch the volume control knob the static from you partially injects the circuit to work and thereby conduct to produce the volume.
The volume controller is an analogue rheostat coupled to a circuit that can be the suspect , it can even be a fault- open circuit- of the controller.
You can remove the top cover after disconnecting the power supply and check behind the volume knob for the circuit. If you are able to test this circuit , it will confirm the case.

I've had the Tonebone Plexitube since January of this year, but have only played through it a couple of times. I recently took it out to really experiment with it and get to know the pedal. Right away...

It sounds like somehow the pre-gain is very high while the volume or post-gain is very low. Try turning the volume high on the effects unit and the gain low, and don't have the amp volume too low either.

Whenever I slightly adjust the "Channel Volume"

You've got a loose wire! What's happening is that there's a bad potentiometer (the electrical component behind the knob) that's out of place and is only connecting fully at one point in the knobs circuit (the part where you get full volume) take it in to an amp tech at your local music store and they'll fix it up easily.

I need to figure out how to open up the subwoofer for the Altec Lansing vs2121 model. Thank you

theres no on/off button for the subwoofer. once you plugged in the power cable,turn on the speaker system by turning the VOLUME knob on the right satellite until you hear a click sound.
An LED will light on the front of the right satellite when the power is ON. if you still dont hear any sound from the sub woofer then check to make sure that all cables are connected properly and are making a clear connection.

hope this 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.

Popping & hardly any volume

i had the first problem and you can probably fix it by turning the volume knob all the way up and down about 20 times. it worked for me. supposedly the potentiometers in the z-5300 get dirty or worn out, somehow this might fix it. for the second problem maybe try plugging it into the laptop and unplugging it again seeing if it goes back to normal?maybe its a problem with the amp?

One speaker not working

jjohnmith

First things first:
1) check your speaker for good connector, and all is working is playing fine.
2) check if your warranty covers one SPK. or RMS
other than that ,
Good Luck
