two broken 30-inch cinema displays hoping to make one working

Hi,

I have one with short-short-long blink issue (display 1)and one with blank display (display 2)but the led is not blinking (continuously on).

how would you move on to make them into one working 30-inch Cinema Display?

display 1 shows an image when doing the flashlight trick against the screen.

display 2 doesn’t

thanks for your advise

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.
