The other day I tried to dust off and use my F3HP for a weekend trip. Put in a fresh set of batteries. Winded the camera to test, and got nothing. The camera is kind of jammed. The LCD does not show anything, which is supposed to show '80' before the counter goes to 1 if I remember correctly. I cannot release the shutter at all. I tried rotating the shutter dial to different speeds, but still cannot release the shutter. And yes, the switch is at the on position with the red dot showing. I haven't used this camera for a long time as I ususally shoot medium and large formats. Maybe I forgot the proper procedure? I did read the instruction manuel again. Any insight? Thanks.
