1-1-1 Servicing the High Voltage VR
and CRT :
WARNING:A high voltage VR replaced in the wrong
direction may cause excessive X-ray
Caution: When replacing the high voltage
adjustment VR, it must be fixed by a
soldering iron after it is properly set.
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.
If the HV VR requires adjustment, (a) Replace the
VR and adjust the high voltage to the specification.
(b) Use a soldering iron to melt the adjustment cap
on the HV VR to prevent any movement.
3. 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.
4. 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.
5. When the HV regulator is operating properly, there
is no possibility of an X-ray problem. Make su
