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.
