This is possibly the most boring video I've ever made because it's instructional and applies to very few devices. But the Dynamic Contrast error, that NEC projectors are prone to, is a pain in the arse so hopefully it's worth it. The error prevents the projector from starting up at all and is really fiddly to fix, but can be done (and it's free). The alternative is getting the projector repaired by an official service centre, which is probably going to be more expensive than buying a new projector in many cases.
The projector featured in this video is the M230X, but should also apply to other projectors that use a similar iris assembly.
Big respect to Philip Tan for the blog post linked below, which is an excellent written guide. This video guide is intended as a video complement, as I needed to dig deeper than the detail described in the blog post in order to fix my problem.
