Troubleshooting
This section may help you isolate the problem and as a result, eliminate the need to contact technical support and allow
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.
