I will attempt to change my Hasselblad 500c screen myself over the next couple months and change the internal light seals - not the dark slide light seals - on an A12 film back (see here for context). I'm leaving up this thread as progress log.
Would it be wiser to send this off to professional? Yes. However, so far, I feel I've seen enough evidence that each is doable. I'll stop and send everything to a professional once something looks dangerous.
Wish me luck. Please share your tips if you've already done this successfully. I have a few questions I have to research:
For the screen
1. What's the part number for the 500c screen's screws? I may try to buy an extra set before starting.
2. What's the part number for any other relevant 500c screen parts? Ditto.
3. Where's an 'official' exploded diagram of the screen and installation instructions?
4. What exact screwdriver type and size should I use to match the screws?
5. What chemicals or lubricants should I have on hand, if any?
6. How do I get a broken screw out if God frowns on me when I try this?
7. Can I re-calibrate focus with a 100mm lens or should I order a 250mm to make it easier?
8. Is there a step by step video out there with helpful viewing angles?
For the A12 film back
1. See questions 1. - 5. above.
2. See question 8. above.

Which Hasselblad to keep? 500c vs 501c
so I have two cameras at the moment and am going to sell one. Both work, but the 501c barn doors seem to be a little worse off for wear? What are everyone's thoughts on this? Better to keep the one that is in better shape? Or the newer one as it still works. How bad do the barn doors look...

Would you fit a Maxwell screen on a 500C ?
Or, if I say it another way : is my 500C worth a new screen ? I have a 500C from 1958, which works fine except for a terrific screen, which makes it difficult to focus when light is low. I'm currently wondering if I should get rid of it and buy a newer model with interchangeable screens, or...

What did I get wrong about the Hasselblad A12 light seal installation for my 500C?
Hi folks. I could use some of your advice. What did I get wrong about the Hasselblad A12 light seal installation for my 500C? I added a fresh set of dark slide seals. However, there's still a light leak. It's not in every frame. I followed the instructions in these videos: 1, 2. Someone on...
