820-00165 Backlight not turning off when close lid


New member
Hi guys I have a liquid damaged 820-00165 of which is fixed the ffedback trace in backlight circuit. Works fine now. However, when I close the lid, the apple logo still lights up. Seems the sensor is not working, where is it located?

You should try to recover that LIO board.
Hall sensor is very easy to locate and follow corresponding trace.
Could be simple as corroded 0 ohm resistor, or LIO connector pin.
