Last night my bb bold 9900 screen went dark I can only just see the writing etc. It didn't get any water damage or dropped and everything seems to be working I just can't see much of it. Anyone got any help?

Re: Screen

Hi coleenD,


Are you able to try adjusting the Backlight Brightness settings to see if that helps? Options > Screen/Keyboard.  If that doesn't help, you may want to try the following to help determine if this is a hardware or software issue. "Using the Self Test application on the BlackBerry smartphone" http://bbry.lv/Ongmxh


If the diagnostic doesn't return any issues, I recommend backing up your data using the BlackBerry® Desktop Software and performing a clean reload of your BlackBerry® Device Software. For further instructions, please see the following KB articles.

For Windows®: "How to perform a clean reload of the BlackBerry Device Software for Windows" http://bbry.lv/GI9beY
For Mac: "Perform a clean reload of BlackBerry smartphone application software using BlackBerry Desktop Software on a Mac computer" http://bbry.lv/J0UN1U
Please test to make sure thebacklight issue has been resolved before restoring any data from your backup file.

Hope this helps.
