NO SOUND COMING FROM SANDISK MP3 PLAYER

if you have already tried different ear phones and if it didn't work then for sure the issue is with the device.I hope those ear phones you tried are working in other audio devices.just try to connect it to a external speaker like computer speakers to see the fault is really with the device and not the ear phones
before assming it as an hardware issue just try to back up whatever you have in the device format the device upgrade the firmware of the device you can do it by clicking here..try hearing the FM radio before going to songs from the computer if the FM radio works fine then try some MP3 format songs you stored in the device from computer..if still you have the same issue.. take it to the sansa repair service center with the bill so that they can help you out..
hope this was helpfull

Try updating the firmware.

check head phones

hold down the power button for 20 seconds

I later found out that while trying to download more songs, the entire songs in my sandisk mp3 was corrupted by a virus. I solved the problem by formatting the device and thereafter downloaded new songs into it. As soon as I did that, the songs started playing normally at full volume.

I Have The Same Problem Only Mine Doesn't Even Work With My Computer Speakers

WHAT DID YOU DO TO SOLYA YOUR PROBLM

reinstall the mp3

hmmmmm is the CD scratched? if you transfer it to the computer, then to the MP3 and the CD is scratched then it comes out all wonky but if the CD is scratched then just ignore it, and heres how you can tell that its the CD not the MP3 ;
some songs are not scratched if all were scratched then the MP3 doesn't work properly.

and thats it

I recently purchased a Sansa e280 and in three weeks of regular use it developed a similar problem, with music cutting out from playing in stereo to mono, coming out of one headphone speaker. Sandisk tech support told me to reformat the device and install the latest firmware, which I did, but the problem continued and occured more frequently. I have returned the player back to the seller and I shall not be getting another one. A nice Ipod alternative from Sandisk, but from what I have seen written about in forums, the Sansa e200 series appears to be buggey with problems.
