Volume dial dosnt work - Harman Kardon AVR 630 Receiver

In most cases the volume dial can be removed by pulling it off, but make sure there is no set screw on the side of the volume, if there is unscrew it.

its as sign that its got shot life to live.get a new 1,

There are often volume buttons or dials below the screen, or on the sides of laptops. Also Vista has a volume control in the bottom right (it looks like a speaker), click on it and drag the slider upwards to make the volume louder.

dear it is fault with music system ,you have to replace stereo.

mute the volume on the stereo system by pushing the volume dial in, waiting a few seconds, then un-muting by pushing the volume dial in once again and you should begin to hear sound again

Hi, The timer has a motor that turns it. If you could get me a model #, I will look this up so I can see exactly what model you have. I have seen some dials hang up because something gets spilled on them and they get sticky betweeb the dial and the control panel.
With a model #. I can see if this is that style.

Thanks

i took my head unit face apart and got the volume control off, sprayed a little WD40 and it worked like a beauty!

i would recommend you ask logitech if they can fix it, if the cost is too high i would go look for other stores that fix speakers, if it still cant be fixed, your better off buying new ones because having speakers like those for 5 years is a long time, it may just be time to change

Try reseting the Yamaha-Shut the power off, and while holding down presets 1,2 and 3 press power on.

If you can't clean the pots or if you just want to try replacing them, try using
500k pots again, in case one or both of the pots is worn or dirty or
defective. If that doesn't work, and cleaning or replacing the
switches doesn't work, then the problem is probably elsewhere.
You could put a 500k resistor (with a sufficiently-high power rating of at least half the power rating (Watts) of the pot) in parallel with the pot, or, to cover all bases, put a 500k resistor from each of the two outer lugs of the pot to the middle lug. That should change it into the equivalent of a 250k pot. You could even just temporarily clip the resistors on, with alligator-clip leads, if you're very careful, just to test it.

Good luck,

The dude.
