Try to reset your SanDisk Sansa as follows:
1. Press and hold the Power/Menu button for about 20 seconds. 2. Release the button. 3. Press the button again to try to turn it on.

Try resetting your firmware via Sandisk's support site. If it still doesn't work, your sansa's mainboard might be busted. The cost of replacing it will be more than a refurbished one (under $40 online).

If you have a microSD or can borrow one try inserting it and turning on the Sansa.  If it works then you will have to reformat the internal memory (you will loose all songs in the Sansa)
I hope this helps.

this should fix it, a tiny software that fixed mine just fine

I found the solution to our problem!! and it is very easy. Take the 4 screws off the back. Remove the battery. Press the on/off switch and all the others on the front. Replace the battery and the screws.

Mine needed to be plugged in again, but the computer could read the Sansa and I can see the screen again. Now it is charging and I think that the problem is fixed.

Good luck!

your battery could be dead. but when you plug it in does the blue ring light up

k, so now the SanDisk sansa m240 1GB mp3 player, when you turn it on, it freezes. I have tried to change the battery and everything and it still wont work. What is happening here? others that have had the same problem. I researched this online and found out that there was a rather large bad batch of these mp3 players shipped in December. they suggest calling sandisk tech support at 1-866-726-3475 for a replacement and getting a RMA number or going back to where you bought it and exchanging it.

try rebooting it or restoring it

Mine does this, and so does my friend's player. Just unscrew the back, remove the battery for 30 seconds, put it back together. Works for me.

The same thing happened to mine. I tried to charge it and the blue light remained on. After an hour or so of trying to charge I disconnected it and pressed the on button and held it for 30 seconds and the light went off and I could turn it on. I then charged it and it appears to be working.
