MacBook Pro 14-inch LCD Replacement

This is a hard and full on repair! Replacing an cracked LCD on a 2021 MacBook Pro Model number A2442 and 2023 MacBook Pro model A2779.

This particular example and the photos are from A2779 model bu the process is identical for A2442.

Why is it so hard? The LCD display is paired with the logic board via two ICs. For the LCD to work correctly it needs to have original LCD chips installed to it. To access the chips, the original LCD needs to be taken off, the chips are located on the under side of the LCD.

There are two chips that need to be transferred, the bigger one, display timing controlled and the smaller one, only 8 pin so probably eprom. We are not 100% sure of their exact role, heavily guarded secret, the  schematic we have for the display does not show what they are.

The smaller of the two ICs is so small it tends to fly off from the board in the process of being removed from the original LCD because of hot air flow used to hear it up. This is a trap for young players, if you lose this chip on the floor, you might never find it again. If you don’t find it, you are in trouble, no way to make the display work again.


Once the ICs have been removed and re-balled, they are installed to the new LCD display. Tip: use ceramic tweezers as the smaller chip can crack easy from pressure.

The surrounding area is best protected by the copper foil to shield the rest of the LCD flex from the heat.

Very time consuming procedure but the result is a much cheaper LCD repair than the Apple authorised display replacement.

Is the cost justified? We think so.
