Your LCD TV when used as a computer display through DVI and/or VGA connection provides a self-test feature that allows you to check whether your LCD TV is
functioning properly. If your LCD TV and computer are properly connected but the LCD TV screen remains dark, run the LCD TV self-test by performing the
following steps:

1. Turn off both your computer and the LCD TV.
2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital(white connector) and the Analog(blue

connector) cables from the back of computer.

3. Turn on the LCD TV.

The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the LCD TV cannot sense a
video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the
screen continually.

This box also appears during normal system operation if the video cable becomes disconnected or damaged.

4. Turn off your LCD TV and reconnect the video cable; then turn on both your computer and the LCD TV.If your LCD TV screen remains blank after you use

the previous procedure, check your video controller and computer system; your LCD TV is functioning properly.
