Help! I got a new MacBook screen installed and now I can't adjust my screen brightness.

If you recently had a screen replaced in your Apple MacBook or MacBook Pro and after your repair you find that you cannot adjust your screen brightness from your keyboard - read on. This is a common problem that usually has an easy solution.

MacBook and MacBook Pro LCD Screen Repair is a very common repair performed by Apple repair centers. During the repair process, the repair company or technician can select from a number of different screens to install into your MacBook or MacBook Pro. Apple uses screens from companies such as LG, Samsung, Chi Mei and Philips. Apple does not manufacture their own LCD and LED Screens for their MacBook and MacBook Pro laptops. During the repair process, some newer model screens may be installed on an older MacBook system and the screen will turn on and look perfect, displaying images and functioning as expected. Even though the screen looks great, you will want to be sure to check to be sure that your MacBook or MacBook Pro keyboard controls are working correctly. If you press the brightness up or down keys and nothing happens, then you have a problem.

If you find yourself in this situation, the first thing you should do is to check which version of the Mac operating system you have installed on your MacBook or MacBook Pro. If you are running Mac OS 10.5 or higher, contact the repair center that performed your LCD Screen Repair, since there may be a hardware compatibility issue with your replacement screen. If you are running Mac OS 10.4 or lower, often you can quickly solve the keyboard brightness control issue by upgrading your operating system to Mac OS 10.5 or higher. Once you perform the upgrade, check your keyboard brightness controls to be sure they are now working properly.
