Possible solution
If the power LED is not lit, push the power switch
to turn the monitor on. If the display unit is powe-
red through the computer, check that the computer
is switched on.
The display unit might be in standby mode. Push
one of the keyboard keys. Check that the keyboard
is properly connected to the computer.
Check that the power cable is correctly connected
to the display unit and to the power outlet.
The graphics adapter refresh rate or line frequency
is set too high. Select another display mode with
lower frequencies.
This message indicates that the signal is missing or
faulty. Check that the signal cable connector is pro-
perly connected and that the connection pins are
not bent or damaged. If the connector is loose,
tighten the connector's screws.
The video signal from the computer does not com-
ply with the VESA DPMS standard. Either the
computer or the graphics adapter is not using the
VESA DPMS power management function.
The screen may seem to flicker when the refresh
rate is less than 75Hz. See the list of recommended
modes in the section Preset timing table.
If your colour is not uniform, demagnetise the
display unit as described in the Degauss section
under OSD adjustments, and make sure that the
display unit is at least 30cm from any other elec-
trical equipment.
Check that the signal cable connector is properly
connected and that the connection pins are not
bent or damaged. Try another colour temperature.
If the picture has strong colour defects, switch off the
display unit and the computer.
Make sure that other electrical devices are at least
30cm away.
Adjust the picture characteristics as described in
the Adjusting the picture section.
A problem with your graphics adapter or display
unit. Contact a service representative.
