Sansa e200 series wheel problem

(1/1)

bwaslo:
My e260 seems to have an intermittent wheel, sometimes it stops scrolling the screen or moving the volume control.  At first I thought it might be a bug since I'm using the daily build, but the wheel also feels different than an e250 of my daughter's, so it's probably mechanical. 

Has anyone else run into this problem and been able to fix it?  Thought I'd ask before tearing into the unit and risking breaking something.

Chronon:
It's pretty easy to take apart.  I have this problem too on an e250 that I bought for my daughter.  I was able to improve things a bit by taking apart the scroll wheel and cleaning the contacts.  This problem can happen as a result of dirt/deposits building up on the electrodes and leading to flaky conduction.

I found a nice tutorial with pictures here.

bwaslo:
Thanks Chronon, I'll get the screwdriver out!

clutch:
Thanks Cronon, when I read contacts I figured I had a chance.  My E200 has been skipping since I bought it off of ebay.  I *thought* it was optical, learned that it is mechcanical.  In a nutshell, remove back cover, remove screws for front cover, get down to looking at metal detail that clips on in four places.  Use fine tweasers or a very small screw driver to pop that off.  Clean conducting surfaces with some deoxit5.

Mine is now fixed.
