Video and Monitor Problems

CAUTION: Before you begin any of the procedures in this section, follow the

safety instructions in the Product Information Guide.

NOTE: See the monitor documentation for troubleshooting procedures.

ENSURE THAT THE CORRECT AUDIO SOLUTION IS ENABLED IN THE BIOS SETUP

PROGRAM —See "System Setup" on page174.

CHECK THE MONITOR CABLE CONNECTION —

• Ensure that the graphics cable is connected as shown on the setup diagram for

your computer.

If an optional video card is installed, check that the monitor cable is connected to

the card, rather than the video connector on the system board.

• If you are using a graphics extension cable and removing the cable solves the

problem, the cable is defective.

• Swap the computer and monitor power cables to determine whether the power

cable is defective.

• Check the connector for bent or broken pins. (It is normal for monitor cable

connectors to have missing pins.)

CHECK THE MONITOR POWER LIGHT —If the power light is off, firmly press the

button to ensure that the monitor is turned on. If the power light is lit or blinking,

the monitor has power. If the power light is blinking, press a key on the keyboard or

move the mouse.

TEST THE ELECTRICAL OUTLET —Ensure that the electrical outlet is working by

testing it with another device, such as a lamp.

CHECK THE DIAGNOSTIC LIGHTS —See "Power Lights" on page81.
