Troubleshooting
• Swap the computer and monitor power cables to determine if the monitor’s power
cable is defective.
• Check the connectors for bent or broken pins (it is normal for monitor cable
connectors to have missing pins).
C HECK THE MONITOR POWER LIGHT —
• If the power light is lit or blinking, the monitor has power.
• If the power light is off, firmly press the button to ensure that the monitor is turned on.
• If the power light is blinking, press a key on the keyboard or move the mouse to
resume normal operation.
T EST THE ELECTRICAL OUTLET — Ensure that the electrical outlet is working by
testing it with another device, such as a lamp.
C HECK THE BEEP CODES — See "Beep Codes" on page 90.
C HECK THE MONITOR SETTINGS — See the monitor documentation for instructions
on adjusting the contrast and brightness, demagnetizing (degaussing) the monitor,
and running the monitor self-test.
M OVE THE SUBWOOFER AWAY FROM THE MONITOR — If your speaker system
includes a subwoofer, ensure that the subwoofer is positioned at least 60 centimeters
(2 feet) away from the monitor.
M OVE THE MONITOR AWAY FROM EXTERNAL POWER SOURCES — Fans, fluorescent
lights, halogen lamps, and other electrical devices can cause the screen image to
appear
shaky. Turn off nearby devices to check for interference.
