***" LED 3*** Indicates that the computer and the LCD display are communicating. This LED will be ON when the computer is turned on and video signal is being generated."

Hello, in my imac (2010) where the screen is also black the LED is on whether the screen is up or not!!!

Why can this happen?

Thanks!
