1-1-1 Servicing the High Voltage and CRT :
WARNING:A high voltage adjusted to the wrong
value may cause excessive X-ray
1. When servicing the high voltage system, remove
the static charge by connecting a 10 kohm resistor
in series with an insulated wire (such as a test
probe) between the chassis and the anode lead.
2. When troubleshooting a monitor with excessively
HV, 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. High voltage should always be kept at the rated
value, no higher. 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.
4. When the HV regulator is operating properly, there
is no possibility of an X-ray problem. Make sure the
HV does not exceed its specified value and that it is
The CRT is especially designed to prohibit
X-ray emissions. 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 discharging the high
7. Do not lift the CRT by the neck.
Fire and Shock Hazard :
Before returning the monitor to the user, perform the
following safety checks:
Inspect each lead dress to make certain that the
leads are not pinched or that hardware is not
