The display is detecting a backlight error. Check your display's power connections and restart the computer. If the problem continues, contact Apple or an Apple Authorized Service Provider.
Well Apple is not going to help you.
Lets go for the cheapest repair first, with it on, hold a flashlight at an angle to the screen and see if you can discern the desktop. If you can, replace the inverter.

UPDATE
The serial number with bar codes is located on a label under the foot of the display. To view the serial number, hold the sides of the display and gently lay the display face down on a soft, clean towel or cloth.

solved : I took the inverter board form the display with continuous led (no blinking led) and put it in the display with short-short-long and works perfectly now
