Safety First

Before we begin, let’s make sure you’re prepared. Working on electronic devices can be dangerous if you’re not careful. Here are a few safety tips to keep in mind:

• Always ensure your device is unplugged from the power source before you start working on it.
• Use an antistatic wrist strap to prevent damage to the device from static electricity.
• Work in a well-lit area with a clean, static-free surface.
• Be patient and take your time. Rushing can lead to mistakes and damage to the device.

What You’ll Need

To replace the main board in your Canon EOS 5D Mark III, you’ll need the following tools and parts:

• A replacement main board for the Canon EOS 5D Mark III.
• A Phillips #00 screwdriver.
• A spudger or plastic opening tool.
• Tweezers.
• Antistatic wrist strap.

Step 1: Remove the Rubber Hand Grips

Start by removing the rubber hand grips from around the camera. Don’t worry, they can be put back without any loss of stickiness. Use your fingers or a spudger to carefully pry them off.

Step 2: Remove the Plastic Around the Viewfinder

Next, remove the plastic around the viewfinder by squeezing the sides and lifting towards the top of the camera. This will expose four screws that need to be removed.

Step 3: Remove the Screws

Remove the four screws from the back of the camera. The top screws are a different size from the bottom screws, so keep the top separate from the bottom. Before you proceed, be sure to label exactly where each screw you remove should go. You’ll notice the plastic container near the top of the picture. There are 5 more like it with tape labels stating where the screws go. There are a lot of different sizes holding this camera together and meticulous planning is necessary. This is very important!
