PPVCC_MAIN Interesting Diode Value
Hello one of my customers brought me an ipad 7 and it is not turning on. When I checked it under the thermal camera saw that big power is getting hot on power supply connected to the battery legs and then sarted measuring PPVCC_Main diode value first and found out that it is around 0.170 and I know that it must be around 0.360 .
Because of this first changed the big power as I thought it is getting hot when I plugged it to the power supply without trigger. Nothing changed then I tried changing U2 and nothing changed with it also. And still same diode value on PPVCC_MAIN line.
What can cause this problem and how can I sort this out?
Will be much appreciated if you can show me a way to sort this out.
Is dit een goede vraag?
