Fixing Nikon D3000 shutter release button error

我的问题

Every time I tried to take a photo, the shutter release button error appeared and I had to retake the photo several times before the camera was able to take the photo properly.

我的修理方法

The repair was very easy to do when following these instructions.

我的建议

I noticed that you don't have to remove the screw in the bottom of the battery place to remove the cameras bottom cover. I only removed the bottom cover, cleaned and lubed the gear wheel. When I tried the camera after reassembling it, it worked perfect. No more shutter release button error!
