Lack of electricity 1. Unlock and remove cabinet cover.
2. Verify that AC Power is connected to the Video
Monitor.
3. Inspect the neck of the CRT under low light level
conditions.
4. You will see a glow near the CRT base if voltage is
in the filament circuits. (This does not mean that
other voltages or signals are as they should be, but
it indicates that some monitor circuits are receiving
power.)
Poor connection 1. Turn OFF VGM power.
2. Verify that the Video Signal and the Remote
Adjustment Board connectors are fully seated on
the Video Monitor Board Assembly.
3. Ensure that the video connector was installed onto
the board with the pins in the same orientation as
the original connector.
4. Check the other monitor connectors in the same
way. Important: Do not operate a monitor
without a Remote Adjustment Board.
Faulty fuse Examine the AC line fuse on the Video Monitor Board
Assembly. If the fuse is faulty, replace it with an
identical fuse of the proper voltage and current rating.
Loose parts Ensure that no loose parts or wires are caught or
pinched by chassis or the mounting brackets.
Reposition the thick, red CRT high voltage wire away
from other components under the CPU shelf.

1. Check that the brightness (intensity) and contrast
have not been set to their minimum levels.
