Issue:

No Input Signal message.

Cause:

This issue can be caused by any of the below possibilities.

1. Monitor not connected properly.
2. Bad hardware

Solution:

Monitor not connected properly

Verify that the monitor is properly connected in the back of the monitor as well as to the back of the computer.

If the monitor appears to be connected properly, verify that a cable is not loose by disconnecting all cables that can be disconnected in the back of the monitor (generally the data cable cannot be disconnected). Next, disconnect the data cable connected to the back of the computer and then reconnect the cable. When connecting the cable in the back of the computer ensure the cable connection is tight. Most Computers will also have screw ends that can be screwed in to hold the connector in place.

Bad hardware

If the connections appear to be correct, unfortunately it is likely that either the monitor or the computer video card is bad. To test which component is bad either connect a different monitor to your computer or connect your monitor to a different computer.

• If another monitor works on your computer it is likely a bad monitor.
• If your monitor works on another computer it is likely a bad video card. Steps on trouble shooting a bad vide card can be found on document CH001028.
