It means that the monitor isn't getting a VGA (blue analog video cable) signal from the pc. This is normal if you use other video cables such the DVI (white) and HDMI (black) cables. In this case VGA won't be active.
I would check the video cable from the pc tower to the monitor. If it's the blue VGA cable then make sure it's plugged in correctly at both ends.
Do you get any video display when you turn on the lcd and pc?

Yes make sure both end are in properly.
Also what is the computer's model number?
Some vista models come with a dedicated pci-e video card. If you have one of those make sure the cable goes to the video card itself and not the onboard graphics whihc is disabled.
You could also try to reseat the RAM sticks in the pc.
If all else fails try another monitor on the pc or try the lcd on another pc.
It could be a bad lcd or motherbo/video card on the computer.

mine turned out to be a bad update. i rolled back three months, and i got my graphics back. i got a motherboard for it but it would not work without startup disc. my other com that went down about the same time required a new monitor. that one worked with an external monitor hooked to it. good luck with your issue. if everything works on another com, try a different monitor.
