Pentax S1a mirror stuck in the raised position

A common symptom on older 35mm SLRs: the mirror stays up and the camera no longer completes its cycle.

When an SLR mirror stays up, the problem is not always the mirror itself. The cause can be dried lubricant, a slow return mechanism, a shutter sequence issue or a small lever that no longer reaches its stop.On this Pentax S1a, the diagnosis starts with the timing of the release cycle before any deep disassembly.The repair is about restoring the sequence, not just pushing the mirror back down.
