1. IMPORTANT SERVICE SAFETY PRECAUTION
@ Service work should be perfomed only by qualified service technicians who are
thoroughly familiar with all safety checks and servicing guidelines which follow:
WARNING
1. For continued safety, no modification of any
circuit should be attempted.
2. Disconnect AC power before servicing.
CAUTION
FOR CONTINUED PROTECTION
AGAINST A RISK OF FIRE REPLACE
ONLY WITH SAME TYPE FUSE. F701 (1.25A,
250V), F702 (2A, 250V), F703 (1.25A, 250V)
FUSE.
BEFORE RETURNING THE MONITOR
(Fire & Shock Hazard)
Before returning the monitor to the user,
ee lieats the following safety checks:
1. Inspect all lead dress to make certain that leads
are not pinched, and check that hardware is not
lodged between the chassis and other metal
parts in the monitor.
2. Inspect all protective devices such as non-me-
tallic control knobs, insulation materials, cabinet
backs, adjustment and compartment covers or
Shields, isolation resistor-capacitor networks,
mechanical insulators, etc.
3. Tobe sure that no shock hazard exists, check for
current in the following manner.
¢ Plug the AC Adaptor directly into a 100~240 volt
AC outlet, and connect the DC power cable into
the monitor's DC jack. (Do not use an isolation
transformer for this test).
¢ Using two clip leads, connect a 1.5k ohm, 10
watt resistor paralleled by a 0.15uF capacitor in
series with all exposed metal cabinet parts and
a known earth ground, such as electrical conduit
orelectrical ground connected to an earth ground.
¢ Use an AC voltmeter having with 5000 ohm per
voit, or higher, sensitivity or measure the AC
voltage drop across the resisor.
* Connect the resistor connection to all exposed
metal parts having a return path to the chassis
(antenna, metal cabinet, screw heads, knobs
and control shafts, escutcheon, etc.) and meas-
ure the AC voltage drop across the resistor.
All checks must be repeated with the AC Adap-
tor plug connection reversed.(If necessary, a
nonpolarized adaptor plug must be used only for
the purpose of completing these checks.)
Any reading of 0.3V RMS(this corresponds
to 0.2 milliamp. AC.) or more is excessive and
indicates a potential shock hazard which must
be corrected before returning the monitor to
the owner.

SAFETY NOTICE
Many electrical and mechanical parts in LCD monitor
have special safety-related characteristics.
These characteristics are often not evident from visual
inspection, nor can protection afforded by them be nec-
essarily increased by using replacement components
rated for higher voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in this manual; electrical
components having such features are identified by
“ A\” and shaded areas in the Replacement Parts Lists
and Schematic Diagrams.
For continued protection, replacement parts must be
identical to those used in the original circuit.
The use of a substitute replacement parts which do not
have the same safety characteristics as the factory
recommended replacement parts shown in this service
manual, may create shock. fire. or other hazards.

AC adapter: UADP-0181CEZZ
DC power supply: 12 + 0.5V
5-2. Special mode setting procedure
(1)After initialization of E7PROM the mode is changed to the adjustment mode.
[Procedure]
Connect TP2007 and TP2008 to GND, and turn on the power.
[Description]
¢ The initialization of microcomputer is as follows.
¢ AV position, DAC data, G/A data, and video chroma data adjustment values are taken as defaults.
(2)Change to adjustment mode
[Procedure]
Short-circuit TP2007 to GND, and turn on the power.
Or short-circuit TP2008 to GND, and turn on the power.
Or holding down the [AV INPUT] key and [MENU] key, turn on the main power, and simultaneously press the (inspection
process) [SELECT W] key and [VOL— ] key to change the mode to the adjustment mode.
[Description]
The manual adjustment or adjustment through communication with the automatic machine is performed.
(3)Inspection mode
[Procedure]
Holding down the [AV INPUT] key and [MENU] key, turn on the power.
[Description]
¢ In the ordinary menu select “PICTURE” with the [SELECT] key, and decide with the [VOL] key. Then select
“CONTRAST”, “TINT (only NTSC)’, “COLOR”, “BLACK LEVEL”, “SHARPNESS”, “RED” , and “BLUE” with the
[SELECT] key, and decide with the [VOL] key. After that, adjust values with the [VOL] key.
¢ in the ordinary menu select “SOUND?” with the [SELECT] key, and decide with the [VOL] key. Then, select “TREBLE”,
“BASS’, and “BALANCE” with the [SELECT] key, and decide with the [VOL] key. After that adjust values witht he [VOL]
key.
* VOLUME, CONTRAST, TINT (only NTSC), COLOR, BLACK LEVEL, SHARPNESS, RED, BLUE, TREBLE, BASS,
and BALANCE change as follows.

(4)Shipping setting mode
[Procedure]
Holding down the [AV INPUT] key and [MENU] key, turn on the main power, and simultaneously press the (inspection
process) [SELECT A] key and [VOL+] key to change the mode to the adjustment mode.
[Description]
User adjustment and other values are taken as defaults.
If AV1 is indicated as SETTING COMPLETE, setting has been completed.
