I have this problem, because my Sansa, hm, has always had some problems with it … Mostly due to the fact I bought it as some ‘refurbished thing’, but whatever. I tried fixing it on my own, and it turned out I am not that handyman - and broke a power button.
Now what was my problem before: the screen would be okay for a moment, but until some time would pass, it would get all ‘fuzzy’’ (like this snowing in olds TVs, if you recall). I found this (http://www.bitofexperience.com/home/miscellaneous/repairs/repair-sansa-clip),,) but it didn’t work (only, as foresaid, I broke my power button).
What is my problem (in addition) now: power button doesn’t work (it’s just gone, a friend o’mine got it removed somehow; it doesn’t turn on (black screen), but is detectable when attached to a PC.
What I need: any help on how I can at least turn it on, use it (without the power button of course); the part which can be soldered, what is it called, this power button, so I can order it online (or some maybe magical way to ‘turn it on’; hardware way).
If it is of any importance, I got Rockbox, but I don’t think it would contribute to any damages, as I have tried to recover it many times (meaning, installing original firmware).
