Hourglass comes on 5-6 times a day and screen goes black

Options > Security options / General settings / Menu / wipe handheld / "Blackberry"(without quotes)
Then the phone will shut off and the hourglass will come on as the phones resetting...

That's the simplest way to do it.

Thank you

Hi there

Whenever your screen goes white again just hit the ALT+RIGHT SHIFT+DEL your blackberry will reset itself. It will go black for about 2 to 4 seconds then you will see the famous blackberry hourglass. Be patient and in about 2 to 5 minutes your blackberry will reset.

Try freeing up some space on your blackberry by deleting some unecessary files and do not run too many applications at once.

buy a new screen 4 ur phone

check display connecters

Your system is corrupted.

First backup your data
Then on your blackberry navigate to the following sections:

1. Options menu
2. Security Options
3. General Settings
4. Menu
5. Wipe handheld

Then restore,

Magnetic damage or water damage is most likely the problem.

However it could have suffered from severe physical abuse or could even contain a virus, do you use the internet on it often?

If the flipping hourglass stays for longer than 2 min our Blackberry may just need a firmware restore. Here's a guide on how to restore the blackberry firmware, the website is at : Restore Blackberry to factory settings.Download the Blackberry Desktop manager and run the application loader. Make sure you check to delete old applications in advanced tab. Carefully all you datat will be wiped.

I would connect the device to a PC and update the OS using Desktop Manager. If you recently installed any application, I would uninstall it as this may cause this type of behavior.

Take your batery out for a minute and put it back in.

Are you sure it is shutting of? It might just be locking, if the screen goes blank after 10 minutes try pressing the * key and call key and it should unlock the screen.
