1-1-1  Warnings

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

heatsinks are potential shock hazards.

1-1-2

Servicing the High Voltage System and
CRT

WARNING: Empty or damaged E

2

PROM may

cause excessive x-ray emissions.

Caution: When replacing the E

2

PROM, IC203 a

high voltage step must be adjusted
until high voltage becomes 24.5 kV.
Standard dump from Softjig does
this.

1.  When servicing the high voltage system,

remove the static charge by connecting a 10k
ohm resistor in series with an insulated wire
(such as a test probe) between the chassis and
the anode lead. (Disconnect the AC line cord
from the AC outlet.)

2. High Voltage Adjustment

This monitor does not need to adjust high
voltage, standard dump from Softjig
automatically adjust the high voltage to
24.5kV.

3. It is essential that service technicians have an

accurate high voltage meter available at all
times. Check the calibration of this meter
periodically.

4. When 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.

5. High voltage should always be kept at the

rated value, no higher. Be sure all service
personnel are aware of the procedures and
instructions covering X-rays. 
The only potential source of X-ray in current
solid state display monitors is the tube.
However, the CRT does not emit measurable
X-ray radiation if the high voltage is at the
high voltage adjustment value.
Only when high voltage is excessive are 
X-rays capable of penetrating the shell of the
CRT, including the lead in glass material.
Operation at high voltages may also cause
failure of the CRT or high voltage circuitry.

6. When the high voltage regulator is operating

properly, there is no possibility of an X-ray
problem. Test the brightness and use a meter
to monitor the high voltage each time a color
monitor comes in for service. Make sure the
high voltage does not exceed its specified
value and that it is regulating correctly.

7. The CRT is especially designed to prohibit 

X-ray emissions. To ensure continued X-ray
protection, replace the CRT with only one that
is the same or equivalent type as the original.
Carefully reinstall the CRT shields and
mounting hardware; these also provide X-ray
protection.

8. Handle the CRT only when wearing

shatterproof goggles and after completely
discharging the high voltage anode.

9. Do not lift the CRT by the neck.
