Having problems with your Samsung SyncMaster 931B 19" LCD Monitor ?

The power light glows solid, but there is no display. The screen doesn't come on at all

Answers :

If the symptoms start from the moment you turn you PC on, and you don't even see the POST messages as it boots, chances are your monitor has given out the ghost. Time to replace it.
\015\012However, if you see some text lines and logos as soon as you turn it on, or turn the PC on, then your monitor may be Ok, and it needs reconfiguring.
\015\012Newer LCDs have a friendly way to tell you when there's a problem and will tell you, for example, when there's NO SIGNAL. What this means is that it may be expecting a Digital signal (DVI) and we're feeding it an Analog one (VGA).
\015\012On older LCDs, that may not be the case.
\015\012It may be possible that either the refresh rate frequency, or the resolution you have set your video card to on your pc/laptop, is too high for your LCD monitor, and it cannot handle these settings.
It would appear that the default refresh rate for LCDs is only 60Hhz.
If your LCD monitor displays text and logos as soon as you turn it on, then try the following:
\015\012Reboot your machine in SAFE MODE, pressing the F8 key repeatedly as soon as the initial POST messages disappear from the screen. Next, select Safe Mode from the different options shown.
Once the PC starts and you're running Windows, go to Control Panel->Appearance and Personalization->Adjust Screen Resolution->Advanced Settings->Adapter->List All Modes and verify that the resolution that's been set is within the range allowed by your monitor. Older ones only go as high as 1024 x 768 pixels in resolution.
Your user's manual should have this information. In case you don't have this information, change it to something safe, like 800 x 600 pixels, at 60Hz refresh rate.
Close all windows, reboot, and Voila! Your monitor is back to life!
Should you wish to continue to improve your monitor resolution, then right click anywhere on an empty spot on your desktop, and choose Personalize->Adjust Display Settings, and try a higher resolution, remembering to leave the refresh rate at 60Hz.
\015\012Should your monitor fail to display even POST messages as it boots, then it may have given out the ghost. Time to pull out your warranty certificate or invoice to see whether you can save on the repairs.
Good luck!
