iPhone SE no touch after water damage (no meson, no cumulus)
My name is Tomáš and recently i get iPhone SE water damage for repair. After water damage i remove motherboard from phone and clean with ultrasonic cleaner. Phone is booting but touch does not work. I measure supply voltages for Meson and Cumulus, there are all OK. I check connector for short and fuses also. All is okej. I replaced Meson and Cumuls from working iPhone 5s. Now touch is working only with china $@$* LCD, with original one does not work. I again replaced touch ICs, this time i use new one from my supplier and same problem. Touch work only with china $@$* LCD, with original one not.
My primary question is, can i use iPhone 5s touch ICs to iPhone SE?
And secondary question, where can be problem when touch work only with china $@$* LCD? Connector resistance is OK.
Is this a good question?
