Confirm that it is not the cable, otherwise it does indeed sound like your monitor is dead.

My monitor does the same thing at times and sometimes shows "No Signal" and at other times the screen will maintain the images but the backgound color switches to mustard yellow. In each of these cases I have been able to solve the problem by unplugging the power cord from the electical outlet for about three seconds and plugging it back in. I have a KDS model 780 LCD.
GOOD LUCK

Try unplugging power cord for three seconds. It works for me.

THE POWER SUPPLY PLUGS INTO A WIRE STICKING OUT OF THE END THAT PLUGS INTO THE COMPUTER

I resolve a similar problem by unplugging the power cord for three seconds.
