Screen is froze on the welcome screen

try preforming a hard reset

Try to scan for viruses , if nothing happened , then try to update firmware !
good luck .

if you're capable of taking off the back of the device,
where the battery is most likely located,
do so and remove the battery.
that should automatically shut it off.
make sure the battery and where it's supposed to be in the mp3 is clean.

put the battery back in, and put everything else back together.
try turning it on.
if this helps, EXCELLENCE!
if not, then you should probably just call the company

if you can still see and detect it with your pc there may be a newer firmware update to fix this issue try and find the firmware and flashing utility from the manufacturer and see if that helps

take the battery out leave out for 10 min then put back in should clear up the freeze

You can try to reset the device by pressing the power button for about15 to 20 seconds..if that doesnt work I would recommend you to go tothe sandisk site to update the firmware on your device or you can contact sandisk to they can help you with updating the firmware on your device..Please follow the link below to get the firmware

My Zen locked when I turned it on. It wouldn't play the track the screen was on so I pressed the reset button and turned it on again. It was then still locked on the same track so I tried turning it off which then froze as it was shutting down. After another reset it went through the rebuild screen then locked again. I then used the above fix (pin in reset, then hold play and power switch down). Taking me into the kind of bios screen I formatted the contents. Then added my library again. It's now working fine.
This is the second Zen I've had because the first one had the same problem so I took it back without trying to fix it. Both times the problem occured when I had my Zen plugged into my car stereo auxiliary jack whilst switching the ignition on in my car. I can't understand why this would cause the problem but I'll avoid doing that in future.

Be sure there is plenty of space around the DVD player. I place mine on top of the cabinet without anything on top if it. Being enclosed seem to affect some DVD players. Also, dust frequently...

Sounds like it may be the index in your Music Library. Try going into Recovery Mode; remove battery, hold power switch to ON, replace battery, release power switch when the Recovery Mode screen appears on the screen. Run Option 1 CleanUP, after it completes run Option 4 Restart. You will get a Rebuilding Library screen when it reboots, that's normal, then it should go back to your startup screen. Good luck and let us know what happened
