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
attached to the cleaning tape.)
