Monitor keeps blank even the power lLED is on green

Hi I have a problem with my monitor CRT 14" 104s. I use it for quite time. Now when I starts the computer the power light goes green but no display appear on screen. I replace with same monitor to check and the video is working fine as usual. Then I replace the power cable and fixed it again and some times the picture comes. i tried this when I got this fault every time and sometime I have to keep fixing the power cable for hours to take the display. suddenly the picture appears. I tried with replacing the power cable and cleaning and adjusting the three power pins in the monitor also. So it's still bugging me. Please give me a good workaround for this.e-mailsahanpere@gmail.com

    When I bring up the computor from idle mode, LCD comes up and green light is on. Display goes blank after 1-2 seconds. Stays blank. If I restart the monitor anywhere from 1-4 times, the display will stay on.

I suspect the problem is with the monitor itself. I have had the same problem. I reported it to Dell and they sent me a new monitor within a few days the problem resurfaced again on the new monitor. They have since sent me a new monitor and the problem has disappeared. The Dell customer service people sounded rather cagy to me when I suggested that this was a problem endemic to this model. The replacement monitor that I have had a sticker on the box that read "refurbished". This is a rather new model of monitor to already be into selling "refurbished" models. If you are still under warranty I suggest you call them. And even if you aren't, call them anyway. I sense that they know about this problem.

You say it's a 14" CRT but you posted the problem under "Likom - HD15A (Black) 15" _LCD_ Monitor" So if it IS a CRT and you've been using it with no problems for some time on that PC it sounds like it's time for a new monitor. You said you tried a second monitor of the same model and it works fine? And you said the power LED stays green when the monitor goes blank so your power cable/connection is fine. Hate to say it but it's time for a new monitor. If you DO have an LCD it could be the back-light inverter board which can be replaced. Good Luck and let me know how it goes, Duder

Next time you get it working, change the resolution on your pc to match the monitor settings, maybe they are 1024 x 768 on your pc but monitor will only allow for 800 x 600. Hope this helps.

If it's working fine in DOS, it can only be your display drivers for your operating system. What happes when you start in SAFE MODE? When you PC starts, keep pressing the F8 key, go to Safe Mode. If it works, bring the Resolution down to 800 X 600 and load the new display card drivers. Restart, should be fine.

Check the information at Viewsonic's website regarding their warranty:

http://www.viewsonic.com/support/warranties/limited-warranty/

If you have your proof-of-purchase and it shows the monitor is less than a year old, it would be covered. You would need to follow the procedure on their website to have the unit repaired or replaced, but it would not be your job to try to fix it.

LCD monitor goes blank


It appears that the display resolution set in your display properties is out of the range that the LCD can display.

Try this.

Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)
