I've got a couple D-40's that are having flash problems, so I started in on one of them tonight.
1. Getting the case apart was no problem. 10 small Phillips screws opens everything up.
2. The flash bulb Assembly is only four screws.
3. Now comes the tough part. I'll have to contact Moultrie tomorrow about a new flash bulb.
I will update this post if/when I make some progress on this little project. I have a bad habit of starting things like this then never finishing.
