I have a Contax 645. OK, it is different but I need some help with it. I have the battery grip for it so I power it with 4 rechargeable AA batteries.
The problem: sometimes without any explanation the yellow exposure scale in the viewfinder goes blank. The f/ numbers and shutter speed info disappear in the viewfinder and the whole camera goes blank. I try to press the shutter button but all I can hear is a clicking noise. I keep trying and all of the sudden the viewfinder is back and I can see the exposure, shutter speed, etc. I have tried to change the batteries and replace them with freshly charged ones but I don't think that the low battery is the problem. I have another Contax 645 and that works without problems with the batteries.
Did this ever happen to you? How can I fix it? I can't rely on the camera if it just decides not to show me exposure, shutter speed, etc info. It always comes back but some times it takes 4-5 minutes... What to do?
Thanks for helping!

I guess not too many people use this particular camera...

Probably not, but I would give it a day or two. I have seen people mention having one on RFF. I think it was rather expensive, using rather expensive lenses. So I don't think it was a popular as say a Pentax or Bronica.
Not knowing anything about these cameras, my first thought is bad contacts somewhere in the electronics, or possibly, an electrical component slowly going dead, such as a condenser of some sort.
Hopefully someone will be able to come up and tell you of a similar experience and what it took to resolve it.
Yes, take off the lens, back, and prism and thoroughly clean all the contacts with a microfiber cloth.
What rechargeables are you using? Does it happen with the standard 2CR5 battery?

Sorry, only just seen this post, but when I used a Contax 645 it did need the contacts cleaning every so often. I don't remember the batteries making any difference, as I just found it was mucky contacts to blame.
