I have read several threads about same issue, but with each thread there are different solutions, I got confused.

I have acer LCD screen connected to WinXP SP2 box, recently I experienced one of these message :

1- ? Input no supported ? .
2- ? No Signal ? and LED turns from green color to amber color.

This happened while the PC is working (i.e. not on reboot)

I thought the problem with LCD screen , I changed to other one , then same message appeared ( ? No Signal ? ).
 
Your PC could have just crashed where the video card stopped sending a signal. Much like your PC failing a POST at bootup with the monitor showing No Signal, it's not actually a monitor problem.
 
Actually it sounds like your PC and monitor are going into stand-by mode. This is normal and it's normal for the monitor to say "No Signal" when this happens. Stand-by is activated to lower the amount of power used by devices. You can adjust this stuff in the Windows Display control panel (right click Desktop, properties, and go to the screensaver tab).
