Introduction

Follow this guide to replace the CMOS board in your PlayStation 5 Pro.

Step 1

Before starting your repair:
Shut down your PlayStation and unplug all cables and accessories.
Remove any stands supporting your console and lay it down so the right side is facing up.

Step 2

Each console cover is secured with hooks along the rear edge and clips along the front edge.
To remove a cover, firmly pull up the front edge to release the clips.
You'll hear distinct "pops" as the clips release.
Remove the cover.

Step 3

Use the same process to remove the three remaining covers.
To reinstall a cover, place the hooks into their cutouts along the rear edge and firmly press the front edge of the cover into place to re‑engage the clips.

Step 4

Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.
Use a Phillips screwdriver to remove the 17.1 mm‑long screw securing the expansion slot cover.

Step 5

Use your fingers to lift the expansion slot cover near the notch by the screw hole and remove it.

Step 6

Use your fingers to remove the plastic cover hiding the fan cables connector.
The cover is secured with light adhesive.
During reassembly, press the piece of plastic back into place to secure it with the leftover adhesive. If it isn't sticking, use strips of double-sided tape to secure it.

Step 7

Gently pull the fan cables out from under their plastic clip on the frame.

Step 8

Firmly grip the fan cables' white connector head and pull it straight up and out of its socket.
If you're having trouble, grip the cables just above the connector head, and gently pull.
During reassembly, align the connector over its socket and push down on the edges with the flat end of a spudger until it slides fully into its socket.

Step 9

Use a T8 Torx Security screwdriver to remove the four screws securing the fan:
One 31.7 mm‑long screw
Two 21.5 mm‑long screws
One 11.5 mm‑long screw

Step 10

Use your fingers to grab the fan by its vents and lift it straight up to remove it.
During reassembly:
This is a good point to clean the fan. Use a clean cloth and some compressed air to remove any dust or dirt.
Insert the fan so its cables are near their connector.

Step 11

A tamper-evident sticker hides one of the right‑side inner shell screws.
If you live in the U.S., you're protected under the Magnuson–Moss Warranty Act and these stickers are illegal—don't let them intimidate you! Elsewhere, warranty protections differ.
Use tweezers to peel up the sticker until you can access the screw underneath.

Step 12

Use your fingers to unclip and remove the plastic grille near the fan recess.

Step 13

Use a T8 Torx Security screwdriver to remove the 10 screws securing the right‑side inner shell:
Four 18.8 mm‑long screws
Two 18.6 mm‑long screws
Four 31.7 mm‑long screws

Step 14

Lift the right‑side inner shell straight up and remove it.

Step 15

Use a pair of angled tweezers to firmly grip the sides of the CMOS board connector, holding the tweezers as close to the connector as possible to get a good grip.
Pull the connector straight up and out of its socket to disconnect it.
If you're having trouble, try rocking the connector side-to-side to loosen it.

Step 16

Use your fingers to lift the CMOS board off the small metal nubs and pull it toward the center of your console to remove it.
If your new board doesn't come with a cable, transfer the original cable to your replacement board.
