Hi,
I have a Sony PMW-Ex3 who been dropped and I have issue with the auto iris. When I set the camcorders on auto iris the shutter will be closed completely. Same when I turn the camera off. Only way to use it is to use iris in manual mode. May it be a simple cable or connection that is loose. I have a service manual an is quite handy but I don't know where to look.

Any suggestion?

Regards Rickard
