Basic Checks:

Run the monitor self-test as instructed in the monitor user’s guide.

Connect the monitor power cable directly to an electrical outlet to

ensure that the monitor turns on. Do not connect it to a power

protection device, UPS, power strip, or extension cord.

Ensure that the monitor power cable is firmly connected, verifying

that the power cable is adequately connected at the monitor and to

the electrical outlet.

Swap the power cables between the computer and the monitor to see

whether the problem symptoms change.

If the monitor display is blank, the computer may be in suspended, or

hibernate, state. Push and release the power button, move the mouse,

or press a key on the keyboard to bring the computer out of the

suspended state.

Disconnect the monitor interface cable from the computer and check

the cable connector for bent or broken pins. Check for damaged or

frayed cables.

If the monitor interface cable is not damaged, ensure that it is firmly

connected to the computer.

Adjust brightness and contrast settings on the monitor.

If the problem still exists after you complete the basic checks, fill out the

Diagnostics Checklist

as you perform the following steps:

1

Turn off the computer, wait at least 30 seconds, and then turn the
