my sansa keeps turning off

my sansa keeps turning off by ts self what should i do

I am almost absolutely sure that it isn’t the issue but check to see if the battery level is okay and in the sleep timer isn’t activated.

for the sleep timer, just go on the main menu, select settings and sleep. make sure it is at 00.

It’s been happening to me too, specifically while docked.  If I pause it, and the backlight goes off - there’s a good chance the Fuze will shut off completely, and reset all settings in the process.  (playback, system)

I’m frustrated because I first thought it was the charger or USB cable, but now it’s happening again.  Aaaargh.

Try a soft reset of the fuze.
