Using the Self-Test Feature when Connected to a Computer

When your computer is connected to the TV display through DVI or VGA connector you can use the self-test feature to check whether your TV display is functioning properly. If your TV display and computer are properly connected but the TV display screen remains dark, run the TV display self-test by performing the following steps:

1Turn off both your computer and the TV display.

2Unplug the video cable from the back of the computer.

3Turn on the TV display. If the TV display cannot sense a video signal and is working correctly, the floating "Self-Test Feature Check" dialog box appears on the screen (against a black background). While in self-test mode, the power light remains blue and the self-test pattern scrolls through the screen continually. This box also appears during normal system operation if the video cable becomes disconnected or damaged.

4Turn off your TV display and reconnect the video cable; then turn on both your computer and the TV display. If your TV display screen remains blank, the problem may be with your computer or graphic card.

See your computer documentation for more information.
