iMac Intel 27" Retina 5K Display 2020 Logic Board Replacement

Introduction

Follow this guide to replace the logic board on a 2020 iMac 27" 5K.

Some photos in this guide are from a different model and may contain slight visual discrepancies, but they won't affect the guide procedure.

Removing the display on the 2020 iMac Intel 27" Retina 5K Display requires cutting adhesive with a specialized iMac opening tool. After you've completed your repair, you'll need to follow our display adhesive guide to scrape off the old adhesive and replace it with new double-sided adhesive strips.

Before beginning any work on your iMac: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors.

Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply.

Are these really pictures of a 2020? I don’t think Apple ever sold any of the 2020 units with a rotational hard drive.

Correct, this is not a 2020 27-Inch iMac.

I tested the procedure and found that these iMacs were similar enough that reshooting photos was not necessary. As noted in the introduction, some photos in this guide are from a different model and may contain slight visual discrepancies, but they won't affect the guide procedure.

Hi all,

Because my iMac A2115 with 512GB SSD has a broken logic board, I am searching for the schematics to be able to see which component needs to be replaced on the logic board.

Hopefully someone here can help me out! :-)

Best regards,

Flo

Is this the same procedure for replacing the logic board on a Mid-2017 iMac? That page doesn't have a repair guide for logic board replacement.
