Correct backlight type for your new screen
Essentially there are two types of backlights currently on the market:
- LED (newer technology)
- CCFL (older technology)
It is extremely important to know your original screen backlight type as they are not interchangeable.
CCFL backlit screens typically have two extra wires, white and pink, sometimes green and blue, that connect to a high voltage inverter which provides high voltage power to the tube light hidden with-in the screen. LED backlit screens typically only have one connector and no extra wires, since the LED backlight low voltage power is supplied directly via the video cable.
