1.Precautions
1-1. Safety precautions
Warnings : Service should
not be attempted by anyone unfamiliar with the
necessary on this Monitor.
The followings are the necessary precautions to be observed before servicing.
1) For continued safety, do not attempt to modify the circuit board.
2) Disconnect the AC power before servicing.
3) When the chassis is operating, semiconductor heat sinks are potential
shock hazards.
1-1-1 Servicing the high voltage volume are CRT Warnings
A High Voltage volume replaced in the wrong direction may cause excessive
X-Ray emissions.
1) Adjust in order to 26KV with signal at Anode.
2)
When the troubleshooting a monitor with excessively High Voltage, avoid
being unnecessarily close to the monitor. Do not operate the monitor for
longer than is necessary to locate the cause of excessive voltage.
3)
Excessive High Voltage can produce potentially hazardous X-Ray RADIATION. To avoid such hazards, the high voltage must be above the
specified limit. The nominal value of the High voltage of this Monitor is
26KV ± 0.3KV at zero beam current(minimum brightness) under a 120V
AC power source. The High Voltage must not (under any circumstances)
exceed 29KV. Each time a monitor requires servicing, the High Voltage
should be checked following the High Voltage check procedure on this
manual. It is recommended the reading of the voltage be recorded as a
part of the service record. It is important to use an accurate and reliable
High Voltage meter.
4)
When the High Voltage regulator is operating properly, there is no possibility of an X-Ray problem.
5) The CRT is especially designed to prohibit X-ray emission. To ensure
continued X-ray protection, replace the CRT only with one that is the
same or equivalent type as the original.
6) Handle the CRT only when wearing shatterproof goggles and after completely.
7) Do not lift the CRT by the neck.

1-1-2. Fire and Shock Hazard
Before returning the monitor to the user,perform the following safety checks:
1) Inspect each lead dress to make certain that the leads are not pinched or
that hardware is not lodged between the chassis and other metal parts
in the monitor.
2) Inspect all protective devices such as nonmetallic control knobs, insulating
materials, cabinet backs, adjustment and compartment cover or shields
isolation resistor-capacitor networks, mechanical insulations, etc.
3) To be sure that no shock hazard exists, check for leakage current in the
following manner.
a. Plug the AC line cord directly into a 120 or 230 Volt AC outlet.
(Do not use an isolation transformer for this test)
b. Using two clip leads, connect a 1.5KΩ, 10Watt resistor paralleled by a
0.15Uf capacitor in serial with an exposed metal chassis part and a
known earth ground, such as an electrical conductor and electrical
ground connected to a earth ground.
c. Use a SSVM or VOM with 1000 ohms per-volt or sensitivity to measure
the AC voltage drop across the resistor.
d. Connect the resistor to an exposed metal part having a return path to
the chassis(metal cabinet, screw heads, knobs, shafts, escutcheon,etc)
and measure the AC voltage drop across the resistor.
e. Any reading of 5.25 volt RMS(this corresponds to 3.5 milliampere AC)
or more is excessive and
indicates a potential shock hazard. Correct
the shock hazard before returning the monitor to the user.

1-1-3. Product safety notices:
Some electrical and mechanical parts have special safety related characteristics
which are often not evident from visual inspection. The protection they give
may not be obtained by replacing them with components rated for higher voltage,wattage,etc. Parts that have special safety characteristics are identified by
△ on schematics and parts lists.
A substitute replacement that does not have the same safety characteristics
as the recommended replacement part might create shock, fire and or other
hazards. Product safety is under review continuously and new instructions
whenever appropriate.
1-2. Servicing Precautions
WARNING 1 : First read the "Safety Precaution" section of this manual. if
unforeseen circumstances create conflict between the servicing
precautions and safety precautions,always follow the safety
precautions.
WARNING 2 : A High Voltage volume replaced in the wrong direction may
cause excessive X-ray emissions.
WARNING 3 : An electrolytic capacitor installed with the wrong polarity might
explode.
1) Servicing precautions are printed on the chassis, and should be followed
closely
2) Always unplug the units AC power cord from the AC power source before
attempting to :(a) remove or reinstall any component or assembly, (b)
disconnect PCB plugs or connectors,(c) connect all test components in
parallel with an electrolytic capacitor.
3) after servicing, always check that the screws, components and wiring have
been correctly reinstalled. Make sure that the area around the serviced
part has not been damaged.
4) Check the insulation between the blades of the AC plug and accessible
conductive parts(examples:metal panels,input terminals and earphone jacks).
5) Never defeat any of the +B voltage interlocks. Do not apply AC power to
the unit(or any of its assemblies) unless all solid-state heat sinks are
correctly installed.
6) Always connect a test instruments ground lead to the instrument chassis
ground before connecting the lead; always remove the instruments lead last.
