After a couple of years of good service, my Minolta Hi-Matic 7s has quit working (naturally, it did it in a non-obvious way that cost me a full roll of really lovely landscapes). I suspect it's due to stuck shutter blades; everything seems to work correctly, except that when fired, the shutter doesn't actually open. I think I can see the blades "twitch" a little, but I can't see any daylight through them at all.
I've never been inside this camera, but I have the impression that the shutter is difficult to get to. Is it sensible to try to get in there and clean it up, or given the low prices of these cameras, should I let it go to someone for parts and get another one?
Any advice welcome...
