iPhone 6 no Power On

Hello,

I got an Iphone 6 wich does not turn on. New Akku installed and USB Charging Port, still dead.

Under the Microskope I see that near the Display Connector one Resistor ist missing

(R2433 Meson to Touch Guard, 0 Ohm) and one Resistor near the Charging Port Connector (FL 1867 BB_GPI03, 120 Ohm). Think both could be shorted for testing.

But I doubt they are the problem for not turning on. Does someone know, which

Ohm Value should be between the + and - terminal of the Battery Connector?

In my case it is only 20 Ohm. Thanks for any help ...
