Pentax 645

I have an older Pentax 645 camera that used to be my father's. I've never used it, nor do I have any documentation for it. He used it quite a bit and I never heard of him having any trouble with it.

I loaded it with six fresh AA batteries and turned it on. The liquid-chrystal display near the eyepiece came on, but a few seconds later it went out, even though the on-off switch was still on.

Pushing the shutter release didn't do anything; the camera didn't fire.

There's no film in the camera.

Does the camera seem to be behaving normally? (Should it fire even though there's no film in the back? And should the display stay turned on?)

I don't know anyone who knows anything about this camera. Nor to I have any film to see if the camera behaves differently when loaded.

Thank you very much.

Try taking the back off- then it should fire, I think.

Hmm...the LCD display should always be on once batteries are loaded with or with out the on switch on. I don't think it will fire with out something in the back. For mine, I have a plastic insert for the back that tells the camera film is loaded so it can fire. But clearly the LCD going out is a concern.

An update: Per the manual (funny how reading the manual helps!), the 645's shutter will operate without any film in the camera if the film holder is removed from the camera. The C/S switch should be set on S, too, the manual says, to avoid complications.

Anyway, camera seems to be operating fine, although I haven't checked everything..

I appreciate everyone's help with this. Have a good weekend. -- Mike
