iPhone 6s blackscreen display not working
hello to all I have an iPhone 6s that after repairing the backlight replacing yarn, at the time of editing the phone did not display anything new, and now my question is backlight the problem I have blackscreen?
I say this because on the lcd pins I have all the resistors backlight while on the PN5V7_LCM_MESON_AVDDN_CONN line I have no resistance.
Sometimes there is and others do not
what can it be ?
Is this a good question?
