PRECAUTIONS IN PART REPLACEMENT
When servicing the unit with power on, be careful to the section marked white all over.
This is the primary power circuit which is live.
When checking the soldering side in the tape travel mode, make sure first that the tape has been loaded and then turn
over the PWB with due care to the primary power circuit.
Make readjustment, if needed after replacement of part, with the mechanism and its PWB in position in the main frame.
(1) Start and end sensors: Q701 and Q702
Insert the sensor’s projection deep into the upper hole of the holder. Referring to the PWB, fix the sensors tight
enough.
(2) Photocoupler: IC901 and IC902
Refer to the symbol on the PWB and the anode marking of the part.
(3) Cam switches A and B: S704
Adjust the notch of the part to the white marker of the symbol on the PWB. Do not allow any looseness.
(4) Take-up and supply sensors: D706 and D707.
Be careful not to confuse the setting direction of the parts in reference to the symbols on the PWB. Do not allow
any looseness.

2-2 CARES WHEN REASSEMBLING
INSTALLING THE CASSETTE HOUSING
When the cassette housing is installed on the mechanism,
the initial setting is essential condition.
There are two initial setting methods, namely electrical and
mechanical.
1. Electrical initial setting
So as to perform initial setting of mechanism execute the
Step 1 of Installation of cassette housing. After ascertaining
the return to the initial setting position install the cassette
housing. (Conditions: When mechanism and PWB have
been installed)
Pinch Drive Cam
Synchro Gear
Master cam
Main Chassis
Drive Lever
2. Mechanical initial setting
• Rotate the worm gear by pushing the flange manually until
return to initial position.
Rotate the flange of worm gear by using thin stick.
CW • • • Loading direction
CCW • • • Ejection direction
Note:
Be careful not to damage the gear of worm gear and
worm wheel gear. It miight cause a strange sound.
• When apply power supply to rotate the loading motor,
please remove/unsolder at least one terminal wire.
• If voltage applied to loading motor without diconnecting
the terminal wire, there is a possibility the capstan motor
IC will damage.
• The maximum applied voltage is 9V. If more than 9V,
there is apossibility the mechanism will damage.
• After ascertaining the return to the initial set position
install the cassette housing in the specified position. (This
method is applied only for the mechanism.)
INSTALLING THE MECHANISM ON PWB
Lower vertically the mechanism, paying attention to the
mechanism edge mode SW position, (Set the mode SW
position to 270° and make sure the master cam position
hole also in 270° position) and install the mechanism with
due care so that the parts are not damaged.
* Please make sure to insert correctly.
If not, strange moving will occur and will couse mecha-
nism damage.

PARTS WHICH NEED PARTICULAR CARE
When installing the mechanism chassis on the PWB unit,
take care so as to prevent deformation due to contact of

5. ELECTRICAL ADJUSTMENT
Notes:
• Before the adjustment:
Electrical adjustments discussed here are often required after replacement of electronic components and mechani-
cal parts such as video heads.
Check that the mechanism and all electric components are in good working condition prior to the adjustments,
otherwise adjustments can not be completed.
• Instruments required:
Colour TV monitor Dual-trace oscilloscope
Audio signal generator AC milli-voltmeter
Blank video cassette tape Alignment tape(VROCPSV)
Screwdriver for adjustment
Colour bar singnal generator
• Location of controls and test points

REPLACEMENT OF IC710(E2PROM)
Servicing precautions
When the IC710(E2PROM) has been replaced, make the following reprogramming.
Depending on models, the IC710(E
2
PROM) has been factory adjusted for its memory function.
Its therefore necessary to reprogram the memory function for the model in question.
Note that the servo circuit requires readjustments for the slow and still modes.
1. Memory function reprogramming.
a. Check the power off.(Power is standby mode)
b. Make for moment short-circuit test point(TP801), located at the front side on the main PWB.
Be sure that all the display light up into the TEST mode.
c. Using the CHANNEL(+) AND (—) buttons, select the right function numbers from JP0 to JP39, which appear in the
display, referring to the E
2
PROM map.
Press the DISPLAY button to pickup the functions(ON) and the CLEAR button to discard the functions(OFF).
DISPLAY and CLEAR buttons, are located on the remote control unit.
∗ when the DISPLAY button has been pressed (ON), the memory function number starts flashing.
∗ when the CLEAR button has been pressed (OFF), the memory function number lights up.
d. Example : "ON" and "OFF" are taken as "1" and "0" respectively.
The numbers JP0 to JP39 are divided into four groups and each groups setting is displayed in hexadecimal notation.

b. Using the CHANNEL (+) AND (-) buttons, select the right function numbers continued from recording preset number
as has been JP0~JP39, which appear in the LCD display, referring to the E

IMPORTANT SAFETY NOTICE:
BE SURE TO USE GENUINE PARTS FOR SECURING THE SAFETY AND RELIABILITY OF
THE SET.
å
PARTS MARKED WITH "
" AND PARTS
SHADED (IN BLACK) ARE ESPECIALLY IMPORTANT FOR MAINTAINING THE SAFETY AND
PROTECTING ABILITY OF THE SET.
BE SURE TO REPLACE THEM WITH PARTS OF
SPECIFIED PART NUMBER.
SAFETY NOTES:
1. DISCONNECT THE AC PLUG FROM THE AC
OUTLET BEFORE REPLACING PARTS.
2. SEMICONDUCTOR HEAT SINKS SHOULD BE
REGARDED AS POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS OPERATING.
NOTES:
1. The unit of resistance "ohm" is omitted (k=1000
ohm, M=1 Meg ohm).
2. All resistors are 1/16 watt, unless otherwise
noted.
3. The unit of capacitance "F" is omitted (
p=
µµ
F).
µ=µ
F,
4. The values in parentheses are the ones in the
PB mode; the values without parentheses are
the ones in the REC mode.
VOLTAGE MEASUREMENT CONDITIONS:
1. DC voltages are measured between points indicated and chassis ground by VTVM, with
AC230V~240V/50Hz supplied to unit and all
controls are set to normal viewing picture unless
otherwise noted.
2. Voltages are measured with 10000
µ
V B & W or
colour noted.
WAVEFORM MEASUREMENT CONDITIONS:
10000
µ
V 87.5 percent modulated colour bar signal
is fed into tuner.
CAUTION:
This circuit diagram is original one. Therefore there
may be a slight difference from yours.
