Service recovery after replacing C1 and C2 on an M645.

Resume

Service recovery after replacing C1 and C2 on an M645.

Symptomes

  • During release, the curtain stayed open and the mirror remained raised.
  • The cycle did not finish immediately.
  • When pressing battery check, the lamp took time to light.
  • When the lamp finally appeared, the cycle then completed.

Diagnostic

The retained hypothesis was a faulty or leaky capacitor absorbing part of the current, which could explain the delayed battery check, abnormal charging behavior, and incomplete cycle until enough charge was reached.

During disassembly, component C2 appeared visually damaged.

Actions

  • Opened the body
  • Visual inspection of the board
  • Confirmation of a visibly damaged C2
  • Replacement of C2
  • Replacement of C1

Resultat

After replacing C1 and C2, the cycle became fully operational again.

A retenir

  • An abnormally slow battery check can be a useful clue for a capacitor issue on this camera family.
  • The open curtain + mirror up symptom is not only mechanical.
  • A simple visual check can quickly guide the diagnosis when a capacitor is already visibly degraded.
