I recently started having a similar issue with my RB67 and the 90mm sekor. Albeit it could be user error, but After attempting long exposures in Mirror Lock up mode the roll came back completely blank. Film was loaded correctly. shutter sounded like it was firing, but didn't know 100 percent. removed back and checked to see if shutter was firing at all speeds, and it was. So Ran a daylight roll through the camera not in mirror lock up and the first 3 frames came back exposed and the rest blank. Now after wasting about 3 rolls of film hesitant to waste another. Curious if this could be a back issue, or just a sticky shutter, or some weird mishap with the mirror lock up switch. Camera is honestly well overdue for a CLA but also am somewhat handy I'm just not sure where to start.

I have the Fujica 690BL with interchangeable lenses. Since I bought it i've only ran rolls through it during the day, all of which came out properly exposed, no issues whatsoever. I took it out the other night for the first time, why not try to shoot 6x9 at night, let's see what happens. What i discovered is that on bulb setting with the cable release attached the shutter was opening when pressing the cable release but not closing after releasing. The only way to release the shutter after opening in bulb setting was to move the shutter setting from B to any other setting on the lens. I'm curious as to what exactly the issue could be since the shutter fires regularly at any of the other shutter settings.
