When your iMac's LCD screen cracks or stops working, it can seem like the end of the world. According to Apple's website, a 2011 iMac can cost anywhere from £779 to over £1,300 depending on the computer's exact specifications. The good news is that you can repair your iMac's broken screen for a small fraction of the cost of a new computer. However, this involves removing and replacing the broken screen completely.
Power down the iMac, relocate it to a padded work surface and place it face down. Unscrew the Phillips screw from the memory cover along the iMac's bottom panel. Remove the cover to reveal the RAM.
Flip the iMac over and place two, industrial-grade suction cups on the surface of the broken screen. The screen's glass cover is held in place by several magnets, so you must use suction cups to remove the screen's class cover, even if it is broken. Press down on each suction cup until they grip the screen. Pull straight up firmly until the screen separates from the iMac's case.
Remove the 12 T9 Torx screws from the iMac screen's plastic bezel frame surrounding the screen. Carefully lift the entire bezel off of the LCD assembly, disconnect the microphone cable from the bezel and set it aside. This will reveal the screen components.
Unscrew the two Torx screws fastening the LCD panel's main video connector to the logic board. Disconnect the cable from the logic board and remove the four Torx screws from each side of the LCD panel. Disconnect the five inverter cables from the LCD panel and lift it out of the iMac's casing.
Repeat this procedure in reverse to install the new LCD screen.
Wear an antistatic wrist strap while dismantling the iMac to avoid any major electrical damage to your computer's internal components.
