Power saving function
This monitor meets the power-saving guidelines set by VESA,
E
NERGY STAR, and NUTEK. If the monitor is connected to a
computer or video graphics board that is DPMS (Display Power
Management Signaling) compliant, the monitor will automatically
reduce power consumption in three stages as shown below
Power mode Power

operation
active off**
(deep sleep)*
power off 1 W (2 W) off
* “deep sleep” is the power saving mode defined by the Environmental
Protection Agency.
** When your computer enters the “active off” mode, the input signal is
cut and NO INPUT SIGNAL appears on the screen. After 20 seconds,
the monitor enters the power saving mode.
*** If the horizontal or vertical sync signal is received by the monitor, the
power indicator may alternately blink green and orange.

Automatic picture quality
adjustment function
When the monitor receives an input signal, it automatically
matches the signal to one of the factory preset modes stored in the
monitor’s memory to provide a high quality picture at the center
of the screen. (See Appendix for a list of the factory preset
modes.)
For input signals that do not match one of the factory preset
modes, the automatic picture quality adjustment function of this
monitor automatically adjusts the picture position, phase, and
pitch, and ensures that a clear picture appears on the screen for
any timing within the monitor’s frequency range (horizontal: 28 –
64 kHz, vertical: 48 – 75 Hz).
Consequently, the first time the monitor receives input signals
that do not match one of the factory preset modes, the monitor
may take a longer time than normal for displaying the picture on
the screen. This adjustment data is automatically stored in
memory so that next time, the monitor will function in the same
way as when the monitor receives the signals that match one of
the factory preset modes.
In all modes as above, if the picture is adjusted, the adjustment
data is stored as a user mode and automatically recalled whenever
the same input signal is received.
Note
While the automatic picture quality adjustment function is activated, only
the 1 (power) switch will operate.

SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly-sol-
dered connections. Check the entire board surface for solder
splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps,
and mounting hardware have been replaced. Be absolutely
certain that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly tran-
sistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
5. Look for parts which, though functioning, show obvious
signs of deterioration. Point them out to the customer and
recommend their replacement.
6. Check the line cords for cracks and abrasion. Recommend
the replacement of any such line cord to the customer.
7. Check the B+ and HV to see if they are specified values.
Make sure your instruments are accurate; be suspicious of
your HV meter if sets always have low HV.
8. Check the antenna terminals, metal trim, “metallized”
knobs, screws, and all other exposed metal parts for AC
Leakage. Check leakage as described below.

(0.75 V)
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500
microampers).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or
RCA WT-540A. Follow the manufacturers’ instructions to
use these instruments.
2. A battery-operated AC milliammeter. The Data Precision
245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are
examples of a passive VOMs that are suitable. Nearly all
battery operated digital multimeters that have a 2 V AC
range are suitable. (See Fig. A)

Installation
Do not install or leave the monitor:
• In places subject to extreme temperatures, for example near a
radiator, heating vent, or in direct sunlight. Subjecting the
monitor to extreme temperatures, such as in an automobile
parked in direct sunlight or near a heating vent, could cause
deformations of the casing or malfunctions.
• In places subject to mechanical vibration or shock.
• Near any equipment that generates a strong magnetic field,
such as a TV or various other household appliances.
• In places subject to inordinate amounts of dust, dirt, or sand, for
example near an open window or an outdoor exit. If setting up
temporarily in an outdoor environment, be sure to take
adequate precautions against airborne dust and dirt. Otherwise
irreparable malfunctions could occur.
Handling the LCD screen
• Do not leave the LCD screen facing the sun as it can damage
the LCD screen. Take care when you place the monitor by a
window.
• Do not push on or scratch the LCD screen. Do not place a heavy
object on the LCD screen. This may cause the screen to lose
uniformity or cause LCD panel malfunctions.
• If the monitor is used in a cold place, a residual image may
appear on the screen. This is not a malfunction. The screen
returns to normal as the temperature rises to a normal operating
level.
• If a still picture is displayed for a long time, a residual image
may appear for a while. The residual image will eventually
disappear.
• The LCD panel becomes warm during operation. This is not a
malfunction.
About the built-in stereo speaker
Be sure to keep magnetic recording equipment, tapes, and floppy
discs away from the speaker’s opening as the speakers generate a
magnetic field. This magnetic field may affect data stored on
magnetic tapes and discs.
About the bright points of light or black dots
Bright points of light (red, blue or green) or black dots
may appear on the LCD screen. This is not a
malfunction. The LCD screen is made with highprecision technology and more than 99.99 % of the
picture element is intact. However, some of the picture
element may not appear or some of the picture element
may appear constantly.
Replacement of the fluorescent tube
A specially designed fluorescent tube is installed as the lighting
apparatus for this monitor. If the screen becomes dark, unstable,
or does not turn on, replace the fluorescent tube with a new one.
