8 Carefully insert the probe under the anode cap.

Warning:

Do not remove the probe from under the

anode cap until power is turned off. Injury or damage to

equipment may occur.

Probe the anode carefully. Serious

damage and injury may occur if the anode cap is knocked

off while the CRT is charged.

9 The reading should be 25.5 to 26.5 VDC on the meter.

This is actually 26 kV ± 0.5 kV. Most of the voltage is

across the high-voltage probe.

10 Turn off the monitor.

11 Unplug the monitor.

12 Remove the probe from under the anode cap.

Note:

If the voltage is outside the acceptable range after

replacing the main deflection board and CRT/video board,

contact Apple Technical Support for a whole unit exchange.
