MALFUNCTION AND CAUSES
Note:
S-LED
=Shutter
speed
LED.
F.P.C.
=Flexible
Printed Circuit.
1) Shutter
does
not operate.
1-1)
Shutter
does
not operate,
and
S-LED
does
not light.
Check:
(1)
Shutter
Base
Plate.
(Bad
contact
of
release
switch).
(2)
Green
lead
wire
of
release
circuit.
(3)
Bad
contact between shutter board
and
F .P.C.
(4)
R12, R13.
(5)
Battery
case
bad
contact. (loose screws,
bad
revetting of lug plate).
(6) Red,
lead
wire from battery
case.
(7) Loose screw
on
F.P.C.
(8) TR-2.
(9)
R10, R24.
(10) C-3,C-4,C-9
( 11) Quartz.
(12) F.P.C.
(
13)
Amp
I ifier.
1-2)
Shutter
does
not operate, but shutter
speed
LEDs light.
Check: (
1)
TF-switch.
(2)
Antiwinding
lever.
(3)
Trigger switch. (should
be
ON when shutter
is
cocked.)
(4) Loose ground screw on the shutter
circuit
board.
(5)
Yellow
lead
wire between shutter
and
F.P.C.
(6)
F.P.C.
(7)
TR-7, TR-8.
(8)
R19, R20, R21.
(9) C-6.
( 10)
Release
magnet.
(11)
OR
baseplate.
1-3)
Shutter
does
not work with winder.
Check: (
1)
TF-switch.
(2)
Bad
contact between connector
base
and
winder.
2) Auto
exposure
is
incorrect.
2-1)
Shutter remains open
("B"
LED
lights), or extremely under
exposed. (over
LED
remains
light.)
Check:
( 1)
(2)
(3)
(4)
(5)
(6)
(7)
(8)
(9)
Incorrect standard voltage.
(adj.
Ra2
to
295mv±5mv.)
Incorrect off-set voltage.
(adj.
Ra1
to
5mv±5mv.)
Variableresistors.
(Ra1-Ra4)
SPD.
Starting position
of
AV
R brush contact.
AVR.
ASA resistor.
F.P.C.
Amplifier.
