Sticky shutter release - Canon 10D Replacement of the Shutter Release Switch

[nilantha]

My 10D had following symptoms:

 

1. main shutter does not work as smoothly as it used to

 

2. most of the time need to press shutter button very hard to take a picture

 

3. however, second shutter on vertical grip BG-ED3 works flawlessly

 

4. RS-80N3 works without any problems

 

Douglas A. Kerr described replacement of 20D shutter release switch.

After items 17 through 21 are removed, disconnect ribbon cable CG2 – 0955 (page 10) to loosen up top cover. You

can see shutter release switch right under the shutter button on the top cover. It is the square shape button with four

connections this needs to be replaced as described by Douglas A. Kerr. After replacing the switch sticky shutter

syndrome is gone for good on my 10D. I would like to thank Douglas for publishing 20D shutter release switch

replacement.

Did you try a squirt of contact cleaner first? Nearly all times this will cure sticky switches. You can depress the shutter button and squirt a short squirt in, and it will clean the contacts well.
