Unexpected clearing out
of REC/PB mode.
Are both the start sensor
and end sensor at "H"
level?
Is the master cam at "PB"
position? (See Mechanism
Operation Flowchart.)
Is the drum motor
running?
Is there the H.SW.P.
output signal?
Is the capstan motor
running?
Is the reel running with the
idler in mesh with the reel
stand?
Go to Flowchart No. 6
"Drum motor failure to
start".
Check IC2001 and
replace as required.
Are there the specified
mechanism position
signals at pins (6) and
(7) of IC2001?
Is the loading motor
running?
Go to Flowchart No. 5
"Loading motor failure to
start".
Loading motor failure to
start.
Are the control signals at
pins (11) and (12) of
IC7006 as specified? (See
the table at right.)
Is PC12V applied at pins
(9) and (10) of IC7006?
Check pins (91) and (90)
of IC2001. Check also the
IC2001 performance.
Replace as required.
Check the PC12V line.
Do the voltages (shown at
right) appear at pins (13)
and (15) of IC7006?
Drum motor failure to
start.
Are 12V and 5V applied
at pins (21) and (3) of
IC7006 respectively?
Check the PC12V and
PC5V lines.
Are there the PWM output
signals at pins (32) and
(34) of IC2001?
Check IC2001 and
replace as required.
Check the line between
pins (32)/(34) of IC2001
and pin (2) of IC7006.
Check the connection
between connectors AD
and ME. Replace the
drum motor.
Check IC2001 and
replace as required.
Does the voltage at pin
(2) of IC7006 become
about 2.6V in the drum
motor startup timing?
Replace IC7006.
Disconnect the loading
motor connector "AL" and
apply external DC voltage
(about DC8V) to the motor
terminal. Does the motor
start?
Check the loading motor
connection with pins (13)
and (15) of IC7006.
Check the mechanism for
overload, and the setup
of relay gear, master cam
and shifter. Replace the
loading motor.
Check the start sensor
(Q7001) and end sensor
(Q7002). Replace as
required. Check also the
cassette tape (for
magnetic substance
peel-off, for example).
Check the setup of relay
gear and master cam.
Check also the
mechanism position
sensors (D7008 and
D7009). Replace as
required.
Go to Flowchart No. 10
"No H.SW.P. output
signal".
Go to Flowchart No. 8
"Capstan motor failure
to start".
Replace the idler
assembly.
Go to Flowchart No. 11
"No supply and take-up
reel pulse output".
