Monitor says no signal when i take the caBLE OUT IT SAYS NO CABLE ALSO THERE is an alarm on

Apparently you have power to the camers. The only other issue is the video cable. Loose connection, corrosion, damaged cable.

The message it is displaying indicates that a VGA cable is connected and is not sending signal, or is sending a Monitor Off signal across the VGA cable. The motherboard battery will have no impact on this. If you are using something other than a VGA cable to send the signal to the monitor, then you should ensure that no VGA cable is plugged into the monitor, or the source on the monitor is not using the VGA connector.

Remove the memory card from the wii , try again and it will work !

Your monitor is telling you that it thinks it is not receiving a video signal from the computer. You need to verify which of three components is not working, the computer, the cable, or the monitor.

The first thing to do, obviously, is to check that the cable connecting the computer to monitor is good. You will need some extra components to do the checking. I'm going to assume that the cable is detachable at both ends.
First you can try replacing the cable with different one. If the replacement cable works, then it's the cable.
Secondly, you can try different monitor. If you connect this in place of the first monitor, and it works, it's a faulty monitor (needs repairing or replacing).
Third try a different computer with the original cable and monitor, if it all works it looks like the video on your PC has malfunctioned. (This might also be your conclusion if a system comprising a different cable and monitor fails to work with the original PC)
You might just be able to verify the cable by testing the connectivity of all the wires in the cable with a meter, if you knew the pin out of the cable at both ends.
If you find out the computer is getting a signal out, there could be many causes for that, each having its own solution (or not as the case may be)

disconnect the signal cable and power on then see the massege on monitors screen "NO SIGNAL CHECK THE SIGNAL CABLE"if it appears then monitor is ok if not then monitor is faulty check the signal cable and replace it if faulty problem will be solved

You have a cable problem as no such thing as a VGA to HDMI cable exists.

HDMI is a didital signal and is thus not compatable with an anolog VGA signal. HDMI to DVI cables however do exist as both are digital signals.

Hope this helps.

had the same issue, called up customer care of samsung and they suggested me to change the cable to D-15 10 series. I was getting the comp o/p on TV but with the "Check Signal Cable" messg with the old VGA cable where some pin is not grounded used for computer to monitor connectivity.
Abhi..

This problem requires you to test both the monitor and the signal input form you cable tv setup. Set the monitor up on a computer and see if it works properly. If it does then you may have a problem with the signal conversion of the cable tv to the monitor. It also could be a weak signal that drops below the monitors sensitivity levels. Have your cable tv repairman check the signal levels on your lines. Another way to test this is to hook up is with a different monitor to test your setup and see if it works. If after testing you find, the monitor does not work properly, then you need to have it serviced. Hope This Helps.

PC is not producing and video signal - can you test it with another monitor or test monitor on another PC or notebook.
