Actually, if I'm not mistaken there may well be a dependency between the camera and the flash, so your repairer may not be wrong in that respect. I'll try and find the reference where I heard that, but in the meantime Alisha ( @flannelist ), what's your experience with bad cameras causing flash issues?

Just to add a bit more, it's not authoritative, but is interesting. From this thread:

I believe when iOS detects a camera hardware problem, it just shuts down the whole camera module, including the flash. Perhaps they are on the same power bus and this just prevents more damage. Kind of speculating here.

Ah, I ran across a comment from Alisha herself regarding this problem, and it appears your repair person is on to something there.

Can speak from experience, this is the case on nearly all iPhones. Faulty camera will cause the flash to not work more often than not. I don't think I have ever replaced a faulty camera that did not also resolve the flash issue. It's pretty unusual for the flash alone to be faulty.
