Northgate 7NSS LCD Monitor

Aug 06, 2006 2 Replies

This little booger was working perfectly until its host computer was turned off to replace the CD-ROM drive. When everything was set back up, it didn't display. You power it on and you see a flicker of black display and then nothing. The green light is on, indicating that it is receiving a video signal. If you un-plug the VGA connection and then plug it back in, for a moment you get a perfect picture of the screen, but only for a moment. A few elusive milliseconds. So, the signal gets through and it does work, to some degree of time. There are no loose connections inside. Any ideas? I appreciate it, thanks!

BdG: Hold a light up near the front of the screen. If you can see the picture, you probably have a backlight problem. Usually the inverter board is bad and is not supplying the high-voltage AC required by the backlight lamps. Sometimes they can be repaired, but they are available on the WEB. Check the small SMD fuse on the board and make sure that you are getting 12VDC to the board. Check for bad electrolytic capacitors. Hope this helps... John
