If you look at the monitor there will be an led light on the front that is always orange or yellow when the computer is off but still connected to the monitor. This led will turn green when the computer boots up, sometimes even showing a "no signal" display before boot. If you see the 'command line' text during the boot process (video info, BIOS version, POST text, etc) then the monitor is being recognized by the computer. If that text goes away and the led goes back to orange then it is a driver or operating system problem. Pressing whatever key is prompted at the lower left of the display, if you have a display, like F1, F2, F10, Delete or whatever will get you to the setup program and all is good with the display/computer connection and a green light will stay on. If you never get that green led light then either the video card is bad or not seated properly

If you dont get a signal to the monitor check these two situations: 1.check if the graphic card is properly inserted(pul it out and then back again) 2.check if the monitor in plug in if yes try to test the monitor maybe it's broken
You should verify if it the monitor or PC problem, you should try another monitor with this PC or try the monitor with another PC to isolate the problem first.
Here is what usually wrong with this monitor: http://s807.photobucket.com/albums/yy352/budm/Optiquest%20Q19WB/
Check physical connections first, check monitor cable if securely plugged in and then check power light of monitor. If power light on monitor is amber or yellow it means that monitor is not getting a signal from cpu/ tower. Try to do a power drain on the computer, remove power cable at the back of the computer and then press and hold the power button for 10 secs, after that plug in power cable again and restart the computer.Check if there is any connection if not then try to use another monitor, a known good one. If you get a video from another monitor it means monitor is already defective.
Do you have two video outputs on your PC ie. one on the motherboard adn a separately installed card maybe? If you do you need to set the BIOS so that it uses the AGP/PCIE video card and not the 'onboard'. Try the onbopard vodeo card first to see if you get a signal there.
If you do NOT have two video outputs, and you can not see a signal then you may have a prblem wiht your monitor itself. Is this a known working monitor to start with?
I have these monitors, didn't you get another cable in the pack which has a vga plug on the end? I have had trouble with those converters, try a DVI to VGA cable
The three boxes represent the built-in diagnostics of the monitor. The letters G is green, B is blue and R is for red, the 3 color guns of the picture tube of your monitor. The words "Self Test" indicates that it is in diagnostic mode since it has powered up, it is also then expecting a video signal from a source to be coming in; the display "Check Your PC And Signal Cable" indicates that it is not receiving any video signal from the source which is your PC or more specifically the PC's video card; and the display "Monitor Working" indicates that the diagnostic has determined that nothing is wrong with itself and therefore it has got to be your PC that is in question. The intermittent appearance of the boxes is when the diagnostics restarts itself and eventually finds the same problem.
To determine if it is the PC or the monitor, use another PC (even a laptop with matching VGA output) and try it with your Compaq monitor, see it it will work or alternately, try a different monitor to connect to your PC. The outcome will determine which is at fault.
If you have determined/verified that it is indeed the PC, you should focus on the video/graphics card. In some PC models/versions, the graphics/video is built-in to the motherboard and you should check the memory since this is shared. The only way is to replace either.
Hope that this be of some help/idea. Pls post back how things worked out or should you need additional information.
I agree it isn?t the monitor but I would suspect the video card you are connecting it to or the PC itself. Generally if a monitor doesn?t detect a video signal it will go into hibernation mode, typically displaying a no signal warning and changing the LED color from green to amber.
When you start the computer is anything displaying at all? Are you sure the PC is powering up and booting?
