BlackBerry LCD Faint. How can

BlackBerry LCD Faint. How can I fix? The handheld's LCD is very faint. Can I make it brighter?
There are two ways you can make it brighter, depending on when you find the LCD to be faint:
If the LCD is faint all the time, even in bright, indoor light, you can adjust the screen contrast. From the Device Options screen, choose Screen/Keypad and adjust the screen contrast to your preference.
If the LCD is faint when you use it in a poorly-lit or dark area, you can turn on the backlighting. Press the ALT key three times. Backlighting turns off automatically if you don't press any key or roll the trackwheel for 10 seconds
