No touch after touch IC replacement (LCM_TO_AP_HIFA_BSYNC short)
recently i repair iPhone 6 plus with not touch, I replace Meson and Cumulus, but touch still does not work. After measure, i found shorted line LCM_TO_AP_HIFA_BSYNC to ground. After remove FL2034 is line still shorted to ground on CPU line. I remove U2403 and Meson but does not help.
Is there any solution how to repair this issue without reball CPU?
Sorry for my bad English.
Is this a good question?
