l CCD-FX73OV is based on model CCD-FX430 (CCD-R(430/FX435/FX53O/FX630 SERVICE MANUAL).
[Main differences]
1. LCD screen addition (SD-14, PD-53 boards addition).
2. Speaker addition.
3. REC switch addition on control switch block (FK).
4. FADER switch addition on control switch block (CK).
5. Boards are changed.
The printed wiring board and schematic diagram for the AU-175 board and MA-209 board are not
shown because basically they are identical to the CCD-FX43O’s AU-1 57 board and MA-l 97 board.
.In this service manual, only the differences from CCD-FX430 is mentioned.
When servicing, see the CCD-FX430/FX435/FX53O/FX630 service manual (9-973-530-l 1) with this.

[HEAD CLEANING]
After an extended period of use the video image may become
indistinct or may not appear at all during playback of a tape. The
cause of this usually are dirty video heads. For remedy, cleaning
of the heads is required.
Check for Head Clogs During Recording
@ Use a blank tape, record a short section, then press the stop
button to stop.
@ Set to recording mode again.
@ If the [ Q ] mark is flashing in the viewfinder at this time,
head clogs are occurred.
Check During Playback of a Tape
@ Play back a pre-recorded tape and display the image on a TV
screen.
@ If there is no sound and the image is unstable, no image
appears on the screen, or tape transport is unstable, head clogs
are occurred.
Remedy
[Cleaning method using a cleaning tape]
l Use the Cleaning Tape. (Please follow the instructions

The adjustment for this unit is performed using the VIDEO
input (VIDEO terminal input) or the camera input. The
camera input can be used for video adjustments only. Use
the VIDEO input for the other adjustments.
When using the VIDEO input, set the power supply
switch to “VTR” or set the “forcible VTR power supply
ON mode” using the adjusting remote commander. (Note
1).
When using the camera input, set the power supply switch
to “CAMERA” or set the “Forcible camera+VTR power
supply ON mode” using the adjusting remote commander
(Note 2).
After completing adjustments, be sure to exit the “forcible
VTR power supply ON mode” or “forcible cameratVTR
power supply ON mode” (Note 3).
The MA-209 board is not used for video adjustments.
Disconnect the following connecton in these adjustments.
1. CN402 of the AU-I 75 board
The cabinet (R) (Power supply switch, camera function
switch, speaker amp.), LCD unit and the view finder need
not be connected if the “forcible VTR power supply ON
mode” or “forcible cameratVTR power supply ON mode”
is set. In this case, disconnect the following connectors.
1. CN503 of the VS-119 board (18P, 0.8 mm)
2. CNlOl of the ZB-2 board (4P, 0.8 mm)
3. CN206 of the VS-119 board (14P, 0.5 mm)
4. CN902 of the DD-71 board (11 P, 0.8 mm)
However, as disconnecting CN.503 of the VS-119 board and
CNlOl of the ZB-2 board means disconnecting the 3V
lithium power supply, data set by the user such as the date,
time, and menu will be lost. After completing the
adjustments, set these data again, and be sure to exit the
“forcible VTR power supply ON mode” or “forcible
cameratVTR power supply ON mode”. (Note 3)
When connecting the cabinet (R) using the extension cord,
use the following type.
1. J-6080-289-A (18P, 0.8 mm)

3-8: LCD SYSTEM ADJUSTMENTS
This adjustments does not have in the CCD-FX430 series, but it
is newly added in the CCD-FX730V.
Note 1: The backlight (fluorescent tube) is driven by a 700
Vp-p, 70 kHz AC power supply.
Therefore, be careful not to touch the backlight holder
as you will receive an electric shock.
Note 2: When replacing the LCD unit, ensure there will be no
damages by static electricity.
[Adjusting connector]
Most measuring points for adjusting the LCD system are
concentrated at CNoO2 of the PD-53 board. Connect the
measuring equipments via the measuring pin tool. The following
table lists the pin numbers and signal names of CNO02.

[Power supply voltage]
Adjust the power supply voltage for the battery terminal so that
Pin @ of the CNOOl of the PD-53 board (LCD UNREG) become
6.5 + 0.1 Vdc.
[Video Input Signal for Adjusting]
If the signal column specifies “Color bar signal whose chroma
signal and burst signal are turned off”, input a color bar signal
whose chroma signal and burst signal have been turned off to the
video terminal as the video input signal for adjusting. Check that
the signal level of Pin @ of CNOOl of the PD-53 board is approx.
1.0 Vp-p before adjusting.
