Samsung Syncmaster913v Monitor. The screen is totally black, but when I remove lead from computer it shows "Check Signal Cable" in colour. Also when I press Menu, in top left hand corner message says (in colour) "Test Good". The monitor has been working perfectly, but I do use the one monitor on a couple of different computers. Have I done something wrong????, is the monitor stuffed, is there anything I can do. I have also tested the monitor on two laptops that have screens that work, but the Samsung does not work with those either.

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Test all power and data leads that attach to your hard drive IDE,SATA the leads from your (motherboard to your hard drive) make sure they have secure dust free connections and are not faulty if its a 40 pin flat ribbon type it will be the first to fail make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even something as small as a faulty electrical fan and its lead can cause you problems computers need all power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error Check your RAM. The RAM is located in the middle of the motherboard. There are tabs that you can push to release the RAM. Remove it and put it back in place until the tabs pop out. Loose RAM can cause your computer not to start properly where you want to see a video signal.

Make sure your graphics card is securely seated with no dust built up or in the socket if you remove your graphics check the socket to make sure its dust free Restart your computer then reinstall it this should activate found new hardware wizard Check the vga lead for secure dust free connection or try another vga lead.

Check signal cables means there's no signal on input. If your PC still shows up on a different monitor then it's a time to replace a mainboard in your monitor.

Well, at least you got it sorted out and everything is working fine now.

check for correct vga cable connection

The monitor shows no signal probably it didnt detect the tower
Ill be advising you to remoev the cable that conencts the cable
used a clean cot or rug clean both ends of the cable , clean also the area whre you plug in the cable , the ports on the monitor and on the CPU make sure its clean .
Then plugged it in , in case nothing happens
try to used another cable that conenct from the monitor to the CPU
you may aslo try to used other CPU to checked if monitor is working fine or try other monitor to checked if the port on the your CPU is working fine

Hi, Hopefully you are seeing this error on the screen of your monitor. If that is the case,
do the following steps.
1 Shut down the computer. To do this, without looking at the monitor, hold the on/off button to your computer in for about 5 seconds. The computer should then shut down.
2 Shut off the monitor.
3 Unplug the video signal cable, the thick one that goes between between the computer and the monitor and then re-insert it observing not to bend any pins. There are two end screws that you will have to be loosened, although they may have not been tightened in the first place. When you reinsert the cable, hand tighten those screws.
4 If there is a similar connector on the back of the monitor, repeat step # 3.
5 Make sure that the signal cable is firmly attached to both the computer and the monitor. 5 Turn on the computer and see if it has solved the problem.
If it does not, examine the cable for signs of damage along it's length.
If it is damaged, replace it. you should be able to get a cable for stores like Best Buy, or possible from a friends old stack of cables.
Hope this helps,
Mark

Get real close to the screen to check if you see any image (an inch close!)

right click on your desktop.go to properties.in properties go to the screen saver tab.click on the screen saver tab.under the screen saver tab you will a tab called power.click on power.change you monitor settings there.let me know if it works

the monitor gets the wrong signal from the computer (refresh rate too high or scan rate too high )
check the screen refresh rate from Display properties / Settings tab / Advanced button / Monitor settings
worse case: damaged hardware

Take the post (power on self test) disconnect vga cable and connect power cable if monitor shows no signal check signal cable massage then monitor is ok fault is in cpu. open it and clean the dust
by vaccum cleaner you will get the display again
