Princeton VL1716 monitor displays "out of range" and the background is black when connected to compaq CPU and pugged on.

unplug monitor cable with power on, see if any message will come up on screen, if message appears , cable replacement needed

Look for bad caps just like the failed PRINCETON as shown in my albums.

You should see both monitors indentfy the one and change it to a lower resolution.

Here is two solutions:

1. Grab a LCD Color Tester, Run it through RGB.
- If it is still white its the LCD
-If it not at all either the inverter board is bad or the mainboard.

2. Sometimes its brightness control, look under the manual.

The highest is 75MHZ and the lowest is 56MHz, ita dipends on what sulution you chose to use, 1024 X 768 is 75MHz, 800 X 600 is 56MHz

To make it easy...here is the manual:)
