Sansa Fuze 8 GB Problem...It's on...But black screen, wont play, wont turn off...Nothing...

I’m very surprised that so many people couldn’t figure out to hold down the power switch for an extended time to reset the device.  That’s pretty standard with most modern electronic devices.  It’s also on page 11 of the User’s Guide.  I know most people don’t read manuals/guides these days, but I would expect people to refer to them if they have a specific problem.
