try holding the menu button and the power button for about 20 secs. this will cause it reset, if this method doesn't work, then hold down the menu button, connect it to a PC then hold down the power button, if you have Itunes installed on your computer, it will alert you that it detects an Ipod in recovery mode, basically after that it'll attempt to fix your problem, and it will be able to turn on again.

try taking the battery out, make sure the ac adaptor is not connected, hold down the power button for 60 secs and then put the battery back in and try turning it on.

ok..idk if this will work but it might...first turn off the sansa...then turn the hold switch on (it should turn red). hold down the record button on the side of the player..then while still holding that hold the power button down...but keep holding them untill a screen shows up saying something about recovory mode..itll say to plug in the usb..u could do that..idk it that will work..it it doesnt instead of plugging in tthe usb in the computer..wait about 15 seconds after the recovory mode screen shows up and then hold down the power button for about 15-20 sec...then itll go all black (including the blue light) press the power button again like u would to turn it on...and everything should be back to normal..hope this helps...:)
