Canon EF 16-35mm f/2.8L USM Main PCB Board Replacement

ID: 179220

Description: This guide shows you how to access and remove...

Steps:

1. If possible, try to work in an environment with minimal dust. The goal is to try to avoid dust from getting inside of the lens as much as possible.
2. Remove the two 3mm JIS #000 screws on the side of the lens mount.
3. Remove the four 8mm JIS #000 screws holding in the metal lens mount.
4. Do not pull up on the lens mount assembly. The contact assembly is still attached and you'd risk damaging the ribbon cable.

5. Gently lift up the side opposite of the contact assembly.
6. Slide your finger (or plastic spudger tool) under the lens mount and pop off the back plastic cover off of the lens.
7. Pull the lens mount assembly up and away from the lens.

8. This step involves handling sensitive electronics. Avoid static discharge.
9. Use a pair of blunt tweezers to remove the two small ribbon cables from the main PCB board.
