Troubleshooting
The floating 'Philips - self-test Feature Check' dialog box should appear on-screen (against a black
background) if the LCD Monitor 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 the LCD Monitor TV and reconnect the video cable; then turn on both your
computer and the LCD Monitor TV. If your the LCD Monitor TV screen remains blank after
you use the previous procedure, check your video controller and computer system; your LCD
Monitor TV is functioning properly.
