Screen won't properly display infomation

[lkc]

My sansa clip is acting strangely- on the display screen, there are moving lines going from right to left that break up the lettering. This started happening a few weeks ago, but the screen would usually right itself after a minute or two. It’s happening again and I’m starting to worry that it is permanently ruined.

Anybody else had experience with this?

I’d try re-setting, reformatting, and re-applying the firmware, and see if that fixes matters.  (Not sure if all 3 are necessary, but why not try the complete approach …)

If it doesn’t fix matters, warranty repair time …
