Re: Problem with the monitor

Have you tried another monitor on the PC? If the cable and connector pins are okay, I would suspect a problemn with the video / signal board inside the monitor.

Re: Problem with the monitor

If your computer is still under warranty, go to authorized service providers so they could replace video cards w/o charge. Otherwise, go to service centers so they could look at video card. It may be damaged and should be replaced.

Remove any speakers or magnets that you might have near the monitor as they can cause visual distortion on your monitor screen.

Power is on but having blank screen

Check on what the color of your monitor's power indicator is. Usually, if its orange or red, it means it's on but is not receiving any video signal from your pc. If it's green or yellow, it is receiving signal so if your screen is blank, check on your monitor's video settings, like brightness could be set to 0 or try to restore your monitor's default settings. You can find these options on your monitor's menu button.

Why would I keep getting a red rectangle box in the middle of my monitor screen that says " CONTRAST 100

It's there to notify you that a setting on the monitor is not wisely selected - lower the contrast to less than 80. Ideally you should reset the monitor to default values - use this option from the menu.

My monitor's color is mixed with the color yellow

There is an option on the monitor to reset colour to factory default. Just bring up the on screen menu by pressing the left most button at the botton. Use the button next to this to highlight the colour settings which I think is the 5th or next to last option down. You will then see the option to reset colour and various other factory default settings. Happy computing

Problem with the monitor


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.

Good luck and kind regards.
