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:
1
Turn off both your computer and the TV display.
2
Unplug the video cable from the back of the computer.
3
Turn 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.
4
Turn 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.
