Display of the monitor is not working

Asked By Mary I Pendleton 40 points N/A Posted on - 11/11/2014

Please help!

I have this issue on my desktop computer. HP Pavilion slim type with windows7 OS. At first it was really working well. But now recently the problem is that the monitor says "VGA no signal". But I can hear the sound of the desktop of win7, so I assume it really starts up, but the monitor is a really black display. The color of the power light of the monitor is orange, if it is working the color is blue. This issue happens about 90% of the time. Sometimes it really does turn on like 10% chance when I turn the computer.

I have already searched through google about this and I tried what they said like removing the cmos battery. And it really works, when I removed the battery then turn the computer on, the monitor still no display and I didn't hear the desktop tone of win7. Then I turned it off. Place the battery again, then turn it on, and it works, the monitor now has a display and working fine. I have done this method like 3x already. I also already set the bios setup to default. But, when I try to restart it, there's this problem again of no display. I am getting tired of removing my cmos battery just to make the monitor display works.

Please help me with this. Thank you.

Display of the monitor is not working

Removing the CMOS battery from the CPU doesn’t really fixes the problem. Aside from that, it will also remove all the settings you saved before and you have to configure it again after reinstalling the battery. If you will keep on doing this, it will annoy you in the long run.

If you have no display on your monitor, it could be a problem with your graphics card. Try first connecting your monitor to a different computer and see if it is working. If there is no problem you should check your video card. If you are using a video card that is not built-in to the motherboard, you should test it on a different computer.

Remove your video card then install it on a different computer. Install the proper driver to make sure it is working. See if it works. If it doesn’t then you should replace it with a new one. But in case you are using a built-in video card, simply purchase a new graphics card and install it on your computer.

It should fix the problem. But in case the problem continues even if you are already using the new video card, the problem is in your motherboard. You should replace your motherboard.

Hello,

How are you? A VGA (Video Graphics Array) connector is a pinned cable that is the standard for connecting Monitor with CPU. Check the plugs at the ends of the VGA cable. Make sure they are plugged securely into the ports on the CPU and Monitor. Tighten the securing knobs at the back of the VGA plugs to completely secure the cables. If this does not fix the problem proceed to the next step. Unplug the VGA cable from the monitor and CPU. Clear the ports and plug of any dust and debris. Also, check the pins in the plugs to see if any are broken off or bent. If this is the case, you may need to replace the cable. Plug the VGA cables back into the CPU and monitor and test the signal again by changing the inputs on the monitor until you come to the VGA input. If it still does not work the cable could have a short in it and will need to be replaced.
