CAUTION! When handling the circuit board a
grounded bench mat and a wrist strap must be
used to prevent ESD damage.
Lift the chassis connector out of the hole in which it is seated
in the left hand wall. Remove the two screws (820325) that
secure the photodiode. Gently ease the photodiode through
the hole in the left wall.
Remove the two screws (820011) and the grounding
attachment (22453). Remove the screw (820011) and the
cable holder (12453). Remove the two screws (820015) and
separate the circuit board from the chassis.
Finally, remove the insulating plate (22746).
* Note! The circuit board (22882) is fixed to the wall by an
insulating double-sided tape, screws and attachment.

Disconnect the spring (814512) from the push rod (22369).
Remove the release bar (30375) by gently lifting it with a
screwdriver so that it is freed from the front gear wheel and
then easing it forward.
Remove the front bayonet plate (30777) by removing two
screws (820015) in each of the right and left sides, two
(821017) in the view finder screen frame and two (823655)
in the bottom plate. Carefully draw the front plate forward.

Note! The drive spring should be held when the gear wheel
is released to prevent damage to the drive spring by
releasing the tension too quickly.

(including auxiliary shutter)
Disconnect the arm (22781) secured to the mirror frame by
a clip (817115). Remove the washer (810649) underneath
the arm. Remove two screws (821017) on top of the
focusing screen frame and six (820015) then partly withdraw
the rear plate. When partly removed, disconnect both the
