Small 29.5 KB RAR for Apple 820-2297, also tagged 051-7482, A000 and LED. Apple pairs 820 board numbers with 051 schematic numbers, and A000 appears to be the drawing revision. The LED tag and a separate archive naming this number as an LED driver board suggest it covers the backlight LED driver. Use it to check the driver input voltage, enable and PWM signals, and the LED strings when the screen shows an image but stays dark. Match the PCB number first.
