Stopped working. I plugged the device in to charge and when I returned from dinner it didn't work, at all. The screen wouldn't turn on, the blue ring didn't light up, and it wouldn't register as being plugged into my computer.

Coil dirty, filter dirty? Could be low on charge or fan motor going bad.

try taking out all peripherals like mouse printer keyboard leave screen pluggged n then press and hold the power button for 2 minutes then plug in your mouse and keyboard and see if it boots hope this helps

I just want to return it!!! Im not going to pay another cent for it!! Why isn't there any instructions posted where it can be returned?

Yes, I have the 2GB Music Tube cube and it stopped working very quickly. The headphones didn't work out of the box either and had to return those. I also bought the Aqua cube and that stopped working also. The aftermarket service is terrible. Lavod website for warranty is rubbish and they will not return customer questions, complaints or exchanges. DO NOT BUY LAVOD, they are junk.

Try inserting a(n) SD chip into the player and then try restarting. If it gets stuck on the refresh database screen, plug it into your computer. It's the only thing that unfroze my e280.

Looks like your screen going to 'kaput' already.....anyway try to reseat the memory modules 1st. If u had the luck..it may works that way.....good luck

my player is 2gb .but now it shows 0mb

I think there's a capacitor that holds a charge for the blue-ring-of-death. The fix is to hold the menu button down for about 30 seconds (blue ring disappears) and continue holding for about 15 more seconds (or until re-boot). The additional time is required to discharge the capacitor.
If that fails, there is a safe-mode: place the device in hold, and press the mic and menu buttons at the same time. This usually doesn't apply to the blue-ring problem, but it may help.

Start with these five simple solutions: Reset, retry, restart, reinstall, or restore

If there is no effect, then you have to contact apple, or your dealer for repairs, becouse a part is most likely damaged.

If you need more assistance let me know. Good luck.

Only 2 suggestions here: 1) Make sure your HOLD switch is not enabled. 2) Try to update the firmware If neither of these work, time to send the unit back to Sandisk
