Volume wheel question

[Bosbeetle]

My volume wheel is getting dodgy... Turning it makes the sound crackle and depending on how I turn it sound will be mono or stereo. I guess this happened when I changed my LCD cable, and put the PCB back in the case. I wonder wether this would be an relative thing to fix myself using a solder iron... (it kind of feels like it's just the contact of the wheel that is dodgy).

I don't want to burden the team with my very old, cracked here and there, opened up (for LCD fixing), black case, first batch pandora. 

So if somebody could reassure me that I can fix this myself it would be great.

Have you tried blowing it out with some compressed air? Often times a bit of dust will work its way between the wheel and the contacts and cause such behavior.

havent tried that but does that also account for the mono/stereo behaviour

Yes. The volume wheel is two concentric variable resistors mechanically linked.

If dirt got between one of the wipers and it's track, then one channel (left/right) would cut out.

Or did you mean that the two channels seem shorted together?

Conductive dirt, p'raps?

Some people suggest using contact cleaner on potentiometers..

since my 1Ghz unit returned from getting its LCD cable replaced my volume wheel has been crackling too, i haven't been noticing any stereo/mono problems though. It's only a minor annoyance to me but i would also like to get this problem resolved

I'l try cleaning it thanks for the tip.

My volume wheel went from very low to very high with no mid range volume function. I throughly cleaned the wheel with a tad of isopropyl alcohol on a q-tip and this was the remedy.

Cleaning it worked I cleaned it with one of those alcohol based glasses cleaning cloth.

Good stuff


Did you have to take your Pandora apart to do this?

I just had to remove the bottom part to lift the PCB a little so I could clean under the wheel
