In order for the lens board retainer to work properly, the self-tapping screws that hold the front and rear lens board retainer plates in position must be fully screwed in. Leaving one or more of these screws partially loose in an attempt to fix the problem is a poor practice and doesn’t address the actual problem.
Just sayin', nowhere in my post did I suggest loosening the screws should be used as an on-going fix. The OP was interested in removing the lens board and nowhere in her posts did she mention looking for a such a B-grade solution. Luckily there are APUG members such as yourself who, owning duplicate hardware, can experiment and determine a process that works better should lens board removal become more than an occasional chore.
