I got a problem, when I was taking to peaces my A70. The original reason of this breaking down was that my USB-port doesn't work anymore with my PC. I tried to reinstall all the camera software, but without success.

Anyway, I took couple of parts away and one little metalpart appeared from somewhere and I really do not know where it should be mounted! It looks like some mechanical bearer so I put all parts together without that unknown part and my camera works as well as before. So if here's some person in this forum who could help me I would be very pleased!
