Iphone 8 plus Not charging after USB PORT slightly wet.
I got this iphone 8 plus today it's only charging wirelessly , not recognizing any USB , so i ran a tristar test on it and it came that ACC1 failed , as well as one time tristar , so i managed to replace tristar 4 times , i changed tigris and still with the same failure and not recognizing any USB cable any help would be highly appreciated.
ACC1 is usually a battery issue, so try a new battery first. Second, diode mode the pins on the battery connector to see what you get. Is there no amp draw on the ammeter?
I did try a new battery and that did not make any differences, its not drawing any amps at all ,
I ran a diode mode test on all the pins and i found pin #31 which is the PP_HYDRA ACC1 CONN Line has a significant low value instead of 0.366 , I only get 0.64
I also got low voltages on PP_HYDRA ACC2 CONN normal value is 0.367 and i got 0.337 , Mike the other question that i have , would it happen that my chips are bad or the iphone 8 and plus mechanism is different?
From my experience, it's always Tigris 2 and not hydra that is the problem with the iphone 8/8+. My symptoms are tristar tester passes, no amp draw on usb ammeter, and low amp draw on the dc power supply. There are no other symptoms.
I got it fixed , but i got another one that tristar is ok but not charging , I will run some test on the connector pins to see why .Mike i am trying to watch the last video the iphone X but i can't find it .
