It's unnecessary to disassemble the camera to this extent. You just need to disconnect the ribbon cable (which involves removing the spring loaded guide next to the door hinge and unlatch the connector underneath) and unscrew the door pivot screw on the underside of the camera. This document lays it out quite nicely:
Very simple and straightforward, actually, compared to some electronic hardware I’ve pulled apart over the years. I do have to admit, though, that I had one foul-up… As I was putting away my tools after I got the display back on the phone and verified it was working, I discovered this big pile of T5 screws on my workbench. Yeah, oops. Had to pull the display off again and reinstall all the midframe screws. Kind of glossed over that step. :D :D
I sure hope you discharged that CRT before you pulled the anode connection! Given that picture tubes are pretty much a thing of the past nowadays, it might behoove you to include a few words about chicken sticks and dealing with 20- 30kVDC.
