You will need to remove the logicboard for the repair. [guide|4822|Here is a guide to to that.] I must warn you it possibly might not be just the LED. LEDs only function properly with a driver chip and series resistor. They tend to burn out quickly with out these items. All of these items could be bad since it stopped functioning. To test if LCD that is bad, measure the voltage drop across it's pins if it is approximately 2 volts or more the LED is likely bad.
