iPad Air 1 does not automatically increase or decrease the screen brightness when it is light or dark in a technique called automatic light sensor error. Most of the sensor wires connected to the main are more or less error-prone. If the iPad Air 1 does not automatically increase or decrease the screen brightness, with the device getting hot and draining the battery, it is determined that the main error is 100%.
Ways to know iPad Air 1 does not automatically increase or decrease screen brightness due to main :
- Changed the sensor wire but still no fix.
Step1: If the error is accompanied by battery drain, the device heats up even though it is not in use.
Measure the 3V voltage supplied to the sensor, if touching, isolate the 3V line capacitors until the touch stops.
Step2: Measure the remaining data lines.
If you lose your resistance, then track and fish the lost yellow line coils.
