hi
i have iphone 6 plus with touch problem first i make jumper M1 pin on u2402 because this pin missing then test with diode value and resistant is normal but touch still disease and i measurement PN5V7_SAGE_AVDDN and this voltage only 5.3v im allready change chestnut (u1501) but the problem same -5v7 still low voltage

Have you tried a known good screen? What is the phones history?
You should not have touched chestnut. Now you have added variables to your repair. I have measured different voltages on that line and yours is acceptable.
You need to diode the connector and find what line is missing. If all the pins measure right I would try another meson than cumulus.

phone was dropped from a few feet before
i was change lcd and problem still same
and diode value on connector was normal,, and change cumulus and meson (i get from normal board iphone) problem still same
