Welcome to the BlackBerry Support Community Forums.
Thanks for the question.
The backlight gets triggered from the sensor close to the top of the BlackBerry Bold 9900 smartphone. If you put your hand over the top of the screen, do you see the keypad lighting up when the screen is up?
Also what version of BlackBerry device software are you running? Type myver in a message to get this info.
I look forward to your reply.
