continued productivity.

Symptom

Check these items

No picture

If neither

6

(power)

indicator nor POWER
SAVING indicator is lit

• Check that the power cord is properly connected.
• Check that the power switch is in the “ON” position.

If POWER SAVING
indicator is lit

• Check that your computer power switch is in the “ON” position.
• Check that the video cable is properly connected and all plugs are’firmly seated in their

socket.

• Check that the 5 BNC’s are connected in the right order, (from power cord side; Red-Green-

Blue-HD-VD)

• Ensure that no pins are bent or pushed in the HD15 connector of the cable.
• Check that the video card is seated completely in a proper bus slot. There may be a

particular bus slot specified for your video board to be seated among

8

, 16, and VL-Bus

slots.

• If the impedance switch on the back of the monitor is set to 75 Q. try switching to 2 kQ or

vice versa.

• Check that the video frequency range is within that specified for the monitor.
• If using a Mac system, check that a proper HD15-D15 adapter is provided to work correctly

with your Mac.

If (!) (power) and POWER
SAVING indicators are
both flashing

• If the impedance switch on the back of the monitor is set to 75 Q. Turn off the monitor, move

the switch to 2 kQ, and turn the monitor on. If the indicators are still flashing, there is a

potential monitor failure. Contact your dealer.

If your computer is a
Macintosh system.

• Check that micro switches are properly set on the Macintosh adapter for your system. (See

the adapter manual.)

Picture is scrambled

• If the impedance switch on the back of the monitor is set to 75 Q, try switching to 2 kQ or

vice versa.

• Check your graphics board manual for proper monitor setting on your Multiscan SE series

monitor.

• Check this manual and confirm that the graphic mode and frequency at which you are trying

to operate is supported. Even within range some video boards may have a sync pulse that is
too narrow for the monitor to sync correctly.

Color is not uniform

• Trip the power switch once to activate Auto-degauss cycle. This function is to demagnetize

the metal frame of the CRT to obtain neutral field for uniform color reproduction. If a second
degauss cycle is needed, allow a minimum interval of

20

minutes for the best result.

White does not look
white

• Check that the 5-BNC’s are connected in the right order, (from power cord side: Red-Green-

Blue-HD-VD)

• Perform color temperature adjustment (page 10).
• If the video format is not listed in the compatibility table on page

6

,-there may be a

background level problem (background too bright or greenish). Try black level toggle switch
(page

11

).

• If your computer is a Macintosh system, check that micro switches are properly set on the

Macintosh adapter for your system. (See the adapter manual.)

Screen image is not
centered or sized
properly

• Adjust “Centering”, “Size” or “Raster Rotation” control (page 9).
• Some video modes do not fill the screen to the edge of the monitor. There is no single

answer to solve the problem. There is a tendency to have this problem on higher refresh
timings and Macintosh video timings.
