What to do when screen remains blank/no image even though I turn on the monitor

Last Update Date : Mar 21. 2018

Refer to this article when screen remains blank / no Image even though I turn on the monitor.

 

Case 1. Screen remains blank

● Make sure the power cord is connected securely and completely at the monitor and at the electrical outlet.

● Some Samsung monitors have a power switch on the back in addition to the power button on the front. If there is a power switch on the back of your monitor, make sure that it is turned on, and then press the power button on the front of the monitor.

● Make sure that the signal cable between your monitor and computer is connected securely and completely to the back of your monitor and to your video card.
NOTE:
If your signal cable is not connected correctly, your monitor will display the "Check Signal Cable" message.

● Check the video card in your computer and make sure it is fully and securely inserted.

● If you are using a DVI cable, press the source button on your monitor and make sure that the source is set to digital.

● If you are using a DVI cable and you disconnected the DVI cable when your PC was running, or you booted your PC before you attached the DVI cable, shut down your computer, reconnect the DVI cable securely, and then reboot your computer.

 

If the suggestions above do not resolve your problem, run a monitor self-test (This sentence will be linked with MON_033) to check whether your monitor is functioning properly.

 

Case 2. No image on screen

If the power LED on your LCD monitor is blinking and you have no images on the screen, either the monitor is in Power Saving mode, or you've inadvertently set your video card to a refresh rate and/or a resolution your monitor can't handle. Both problems are addressed below.

 

● Power saving mode

To get your monitor out of power saving mode, press a key on the keyboard to activate the monitor and restore the image to the screen. If there is still no image and your monitor has a source button, press the source button. Then, press any key on the keyboard again to activate the monitor and restore the image on the screen. If this does not work, go to the section on pressing the Auto Adjust button below.

● Press the Auto Adjust button

Press the Auto Adjust button on your monitor. This will adjust your monitor to the incoming signal and may give you a picture and let you reset the refresh rate and resolution in regular mode. If you do get a picture, follow the directions immediately below to change the refresh rate and resolution.

● If your screen is still blank, you need to do the following :

Boot into VGA Mode if you are using Windows 2000 or XP and re-set the refresh rate or resolution.

Instructions for each of these actions are below :

 

To Boot into VGA Mode in Windows XP

● Power off your computer and leave the monitor on.

● Wait approximately one minute, power on your computer, and then press the F8 key along the top of your keyboard repeatedly. The Windows Advance Options screen appears.

● Select the Enable VGA option, and then press Enter. Windows boots into VGA Mode.

Note:  By selecting Enable VGA mode in Windows 2000 and XP this automatically sets the refresh rate to 60Hz.

● Follow the directions for changing the refresh rate and resolution in Windows 2000 and XP above. When you are done, shut down your computer, and then re-boot into regular mode.
