SCREEN BURN
Machine Noise Information Ordinance 3. GSGV,
January 18, 1991: The sound pressure level at the
operator position is equal or less than 70 dB(A)
according to ISO 7779.
Improper operations, in particular alternation of high
voltage or changing the type of tube may result in x-ray
emission of considerable dose. A unit altered in such a
way no longer meets the standards of certification , and
must therefore no longer be operated .
• Unplug this unit from the AC outlet and refer servicing to
qualified service personnel under the following conditions:
- when the power cord is frayed or the plug is damaged,
- if liquid has been spilled into the unit,
- if the unit has been dropped or the cabinet has been
damaged,

IBASIC CONNECTION EXAMPLE
• Before connecting your system, make sure that all units are turned off.
• The illustration below shows some examples of different connections. Terminal connections may differ depending on the component connected.
Be sure to refer to the instructions provided with the unit(s) you are connecting. ·
• Each pair of input (IN) and output (OUT) terminals are bridge-connected.
• If you're not connecting any equipment to a bridged output (OUT) terminal, be sure not to connect any other cables to the bridged output (OUT)
terminal as this will cause the terminating resistance switch to open (auto terminate function).
• When making a bridge connection, connect the input (IN) and output (OUT) terminals on the monitor to separate video components.
(For example, if both terminals are connected to the same VCR, resonance may occur except during playback. This is caused by the same video
signal "looping" between the VCRs, and is not a malfunction.)
• Select the video input (INPUT A (VIDEO) or INPUT B (VIDEO /Y/C)) with the INPUT SELECT buttons on the front panel. When both VIDEO B
terminals are connected (input) at the same time, the Y/C terminal is given priority.
• The ASPECT RATIO or INPUT NB settings can be controlled via the REMOTE terminal by setting ASPECT REMOTE or INPUT REMOTE in the
<SET-UP MENU> screen to valid. (Refer to pages 9 and 10.)

The following are not malfunct ions:
• When a bright still image (such as a white cloth) is displayed for a long period, it may appear to be coloured .This is due to the
structure of the cathode ray tube and will be deleted when another image is displayed .
• You experience a mild electric shock when you touch the picture tube.This phenomenon is due to a normal buildup of static
electricity on the CRT and is not harmful.
• The monitor emits a strange sound when the room temperatu re changes sudden ly.This is only a problem if an abnormality
appears on the screen as well.
• If two or more monitors are operated next to each other, their images may shake or be distorted. This phenomenon is due to
mutual interference ; it is not a malfunction. Move the monitors away from each other until the interference disappears or turn
the power off on any monitor that is not being used.

SAFETY PRECAUTIONS
1. The design of this product contains special hardware, many
circuits and components specially for safety purposes. For
continued protection, no changes should be made to the original
design unless authorized in writing by the manufacturer.
Replacement parts must be identical to those used in the original
circuits. Service should be performed by qualified personnel
only.
2. Alterations of the design or circuitry of the products should not be
made. Any design alterations or additions will void the
manufacturer's warranty and will further relieve the manufacturer
of responsibility for personal injury or property damage resulting
therefrom.
3. Many electrical and mechanical parts in the products have
special safety-related characteristics . These characteristics are
often not evident from visual inspection nor can the protection
afforded by them necessarily be obtained by using replacement
components rated for higher voltage, wattage, etc. Replacement
parts which have these special safety characteristics are
identified in the parts list of Service manual. Electrical
components having such features are identified by shading
on the schematics and by (Lt.) on the parts list in Service
manual. The use of a substitute replacement which does not
have the same safety characteristics as the recommended
replacement part shown in the parts list of Service manual may
cause shock, fire, or other hazards.
4. Don't short between the LIVE side ground and ISOLATED
(NEUTRAL) side ground or EARTH side ground when
repairing.
Some model's power circuit is partly different in the GND. The
difference of the GND is shown by the LIVE : (1-) side GND, the
ISOLATED(NEUTRAL) : ( J,) side GND and EARTH : (@) side
GND. Don't short between the LIVE side GND and
ISOLATED(NEUTRAL) side GND or EARTH side GND and
never measure with a measuring apparatus (oscilloscope etc.)
the LIVE side GND and ISOLATED(NEUTRAL) side GND or
EARTH side GND at the same time.
If above note will not be kept, a fuse or any parts will be broken.
5. If any repair has been made to the chassis, it is recommended
that the B1 setting should be checked or adjusted (See
ADJUSTMENT OF B1 POWER SUPPLY).
6. The high voltage applied to the picture tube must conform with
that specified in Service manual. Excessive high voltage can
cause an increase in X-Ray emission , arcing and possible
component damage, therefore operation under excessive high
voltage conditions should be kept to a minimum, or should be
prevented. If severe arcing occurs, remove the AC power
immediately and determine the cause by visual inspection
(incorrect installation, cracked or melted high voltage harness,
poor soldering, etc.). To maintain the proper minimum level of
soft X-Ray emission, components in the high voltage circuitry
including the picture tube must be the exact replacements or
alternatives approved by the manufacturer of the complete
product.
7. Do not check high voltage by drawing an arc. Use a high voltage
meter or a high voltage probe with a VTVM . Discharge the
picture tube before attempting meter connection, by connecting
a clip lead to the ground frame and connecting the other end of
the lead through a 10kQ 2W resistor to the anode button.
8. When service is required, observe the original lead dress. Extra
precaution should be given to assure correct lead dress in the
high voltage circuit area. Where a short circuit has occurred,
those components that indicate evidence of overheating should
be replaced. Always use the manufacturer's replacement
components.
9. Isolation Check
(Safety for Electrical Shock Hazard)
After re-assembling the product, always perform an isolation
check on the exposed metal parts of the cabinet (antenna
terminals, video/audio input and output terminals , Control knobs,
metal cabinet, screw heads, earphone jack, control shafts, etc.)
to be sure the product is safe to operate without danger of
electrical shock.
(1) Dielectric Strength Test
The isolation between the AC primary circuit and all metal parts
exposed to the user, particularly any exposed metal part having a
return path to the chassis should withstand a voltage of 3000V
AC (r.m.s.) for a period of one second.
(.... Withstand a voltage of 11DOVAC (r.m.s.) to an appliance
rated up to 120V, and 3000V AC (r.m.s.) to an appliance rated
200V or more, for a period of one second.)
This method of test requires a test equipment not generally found
in the service trade .
(2) Leakage Current Check
Plug the AC line cord directly into the AC outlet (do not use a line
isolation transformer during this check.). Using a "Leakage
Current Tester", measure the leakage current from each exposed
metal part of the cabinet, particularly any exposed metal part
having a return path to the chassis, to a known good earth
ground (water pipe, etc.). Any leakage current must not exceed
0.5mA AC (r.m.s.).
However, in tropical area, this must not exceed 0.2mA AC
(r.m.s.).
• Alternate Check Method
Plug the AC line cord directly into the AC outlet (do not use a line
isolation transformer during this check.). Use an AC voltmeter
having 1000 ohms per volt or more sensitivity in the following
manner. Connect a 1soon1OW resistor paralleled by a 0.15µF
AC-type capacitor between an exposed metal part and a known
good earth ground (water pipe, etc.). Measure the AC voltage
across the resistor with the AC voltmeter. Move the resistor
connection to each exposed metal part, particularly any exposed
metal part having a return path to the chassis, and measure the
AC voltage across the resistor. Now, reverse the plug in the AC
outlet and repeat each measurement. Any voltage measured
must not exceed 0.75V AC (r.m.s.). This corresponds to 0.5mA
AC (r.m.s.).
However, in tropical area, this must not exceed 0.3V AC (r.m.s.).
This corresponds to 0.2mA AC (r.m.s.).
