Question about Computer Monitors

Computer boots fine but the monitor is blank

I have a Samsung CRT monitor. sometimes when i turn on the computer the monitor is blank, but the computer boots fine. when this happens i have checked plugging the vga cable of the monitor to the laptop vga port and the monitor works just fine. sometimes the monitor works and in such a situation, if i shutdown the computer and turn it on again sometimes the monitor is blank. im begining to think this could be something wrong with the mother-board. cannot say for sure when it would work or when it wouldnt. sometimes it works for 2-3 days without any problem and stops working for another 2-3 days.the first time this started i was working with the computer and the whole screen suddenly went white. then i turned the computer off and then turned on again, then the monitor was blank.

Thanks,
Dhanushka

If the monitor works fine on your laptop, the problem definitely is at the computer, possibly with the video card (if it is using one). it could have loose connection, or parts might have damages. it seems the problem is intermittent so electronic component of the video card could have parts partially damages or leaky components.
if your still using the motherboards built in video out put, try installing a new video card.

When I switch on my computer, Windows XP start loading and then my Samsung Samtron 45Bn monitor's screen goes blank and the green light keeps flashing every 0.5 secs.


It sounds like your video is set to the wrong resolution. Try booting into safe mode by pressing F12 at the start of the boot process. If you get into windows that way, then adjust the display to something you monitor can display like 1024x728@32bits. The monitor can only display a certain amount of pixels and if you set the video card to high you will lose visual. Hope this helps.
