How to Replace the Macbook Unibody Glass LCD
It used to be that if your screen cracked on your laptop, you'd just replace the LCD and be done with it. That unfortunately is no longer the case. With the introduction of the Unibody Macbook and Macbook pro models, Apple changed the design of the display assembly. Now, there is a glass panel assembly that is placed on top of the LCD panel. The good news is that it is possible to crack just the glass panel and save yourself some money. The bad news is that it is also possible to crack both the glass panel and the LCD.For more Mac Repair guides as well as replacement parts, visit:http://www.powerbookmedic.com/mac-repair.phpIf you take your Macbook to most repair companies with a cracked display, they'll undoubtedly say you need to replace the entire display assembly and charge you some astronomical figure.

To begin, use a heat gun to loosen the double sided adhesive strip that holds the glass in place. Use caution, and heat the glass in short segments as over heating can cause damage to your LCD.With the glass heated, place a strong suction cup on the glass and pull up and away from the glass.
