1. No drive signals supplied at motors
Check drive signals at pins 1 and 2 of K16M for focus
motor, pins 3 and 4 of K16M for zoom motor and pins 1
and 3 of K16L for lens shift motor on M Drive Board. 
Check drive signals at pins 2 and 10 of ICs IC1611,
IC1602 and IC1601.
Check ICs IC1611, IC1602 and IC1601 and peripheral cir-
cuits. Check motor drive power supply (15.7V).
2. No drive signals supplied at motor drive ICs.
Check drive signals at pins 5 and 6 of ICs IC1611, IC1602
and IC1601. They are supplied from pins 4 and 5 for focus
drive, pins 6 and 7 for zoom drive and pins 9 and 10 for
lens shift drive of IC1641 D/A control IC. 
3. No drive signals output from CPU.
The motor dive signals are supplied from IC801, main
CPU, via the IIC bus control lines.
4. No key switch signals input to CPU.
Check signals at pins 118 to 120 of IC801 when pressing
the key buttons. Check key buttons.

■Cleaning
Cleaning with air spray
1. Remove the cabinet top following to “Mechanical
Disassemblies”.
2. Clean up the LCD panel and polarizing plate by using
the air spray from the cabinet top opening.
Caution:
Use a commercial (inert gas) air spray designed for
cleaning camera and computer equipment. Use a resin-
based nozzle only. Be vary careful not to damage opti-
cal parts with the nozzle tip. Never use any kind of
cleanser on the unit. Also, never use abrasive materials
on the unit as this may cause irreparable damage.
After long periods of use, dust and other particles will accumulate on the LCD panel, prism, mirror, polarized glass,
lens, etc., causing the picture to darken or color to blur. If this occurs, clean the inside of optical unit.
Remove dust and other particles using air spray. If dirt cannot be removed by air spray, disassemble and clean
the optical unit.
Disassembly Cleaning 
Disassembly cleaning method should only be per-
formed when the unit is considerable dirty and cannot
be sufficiently cleaned by air spraying alone. 
Be sure to readjust the optical system after per-
forming disassembly cleaning.
1. Remove the cabinet top and main units following to
“Mechanical Disassemblies”.
2. Remove the optical base top following to “Optical Unit
Disassemblies”. If the LCD panel needs cleaning,
remove the LCD panel unit following to “LCD panel
replacement”.
3. Clean the optical parts with a soft cloth. Clean
extremely dirty areas using a cloth moistened with
alcohol.
Caution:
The surface of the optical components consists of mul-
tiple dielectric layers with varying degrees of refraction.
Never use organic solvents (thinner, etc.) or any kind of
cleanser on these components.
Since the LCD panel is equipped with an electronic cir-
cuit, never use any liquids (water, etc.) to clean the unit.
Use of liquid may cause the unit to malfunction.
