There are little tube lights in the monitor that are like the big florescents in buildings. They are powered by a voltage inverter. What you are talking about sounds like the inverter. If it was the lights you would have gotten bad color before it went out.
The inverter is inside the monitor. IT is a little skinny looking board with wires coming in and out of it and it is about .75 inches by 2 inches long .Look up the numbers on the board and see if you can find them on google. If not post them here and I will locate them for you.
