If the display on your Apple Cinema Display M8149 isn’t turning on, is pixelated, or is cracked, use this guide to replace the LCD screen.
The LCD (liquid crystal display) screen is for displaying computer-generated images. Liquid crystals use a backlight or reflector to produce images in color or monochrome. An LCD screen with a faulty backlight or reflector can cause a display to not work properly.
Before using this guide, if the display is cracked or shattered, clean up shards of glass before and during replacement. Additionally, make sure to unplug the display to prevent damage.
In this guide, you will be removing the back cover and two different circuit boards before removing the LCD screen.
After performing the screen replacement, the screen will turn on to display images.

Does anyone know where to get an inexpensive LCD replacement. Mine went primarily magneta except for the outer edges after zapping the pram?! Totally bummed as I bought a DVI to ADC power source and now the monitor is useless in it’s current state. C’est la vie!
