Where is the location of the magnets and its Sensor for the sleep mode? My DS wont boot anymore , Black Screen After powering Up and I tried everything ( Wifi, checked cables ) and my last idea is that something is wrong with the magnets so it is forced to sleep.

Hi! The magnets are located in the area near the power button/ underneath the B button.

Cant find it. Is it on the PCB Platine bottom/top or inside the case?
