Troubleshooting
NO POWER • Flip the Power switch ON. The
Power LED turns on.
• Make sure the A/C power cord is
securely connected to the power
jack and to a power outlet.
• Plug another electrical device (like
a radio) into the power outlet to
verify that the power outlet is
supplying the proper voltage.
• Make sure the video cable attached
from the monitor is tightly secured
to the video output port on the back
of the computer.
• Adjust the brightness and contrast.
• Not enough power is being
supplied to the LCD monitor.
Connect the LCD monitor to a
different outlet. If a surge protector
is being used, there may be too
many devices plugged in.
• See Timing Guide Section of this
manual with a list of refresh rates
and frequency settings showing the
recommended setting for the LCD
monitor.
• If any colors (red, green or blue)
are missing, check the video cable
to make sure it is securely con-
nected. Loose pins in the cable
connector could cause a bad
connection.
• Connect the LCD monitor to
another computer.
• Check the graphics card for proper
sync scheme (or sync polarities) to
match the LCD monitor’s specifica-
tions.
