  • iPhone 7 Plus not Charging,already Replaced Tristar and Tigris

    iPhone 7 Plus not Charging,already Replaced Tristar (twice) and Tigris, No prior repairs or water damage. All are normal diode mode and dock connector, Checked for shorted caps around Tigris and Tristar all are good, also tried a known good power flex. still not charging, the unit boots and everything is ok just not charging, No charging logo, no amp draw on amp meter.
    any suggestions?

    are you getting 5v usb all the way at tigris and tristar? Check the schematic and follow 5v usb, then do a voltage test nearest to tristar.

      This is unclear. Do you have 5v usb arriving at tigris and tristar or not?
