i have a water damaged iphone 6s. both of the water contact indicators are red. i have put in a good battery and a known good LCD screen, no activity. i have tested the screen that came with it on a good phone and the button, digitizer and display all work fine. i am able to get the phone into both Restore and DFU mode and have updated the IOS to 14.1. so here’s the problem. the mobo seems to work well enough - boot, update IOS, talk with itunes - but there’s no visual activity, even with a known good LCD unit. the connectors for the LCD are part of the motherboard, so i’m thinking that while the motherboard is mostly good, there’s probably some visual circuitry that has been compromised. is there any way to troubleshoot that? on a side note, i know the “rice trick” doesn’t really work (and personally, i’d rather eat the rice that use it for rehabbing phones), but i was thinking of putting my phone in a bag (and frame to create space) along with some desiccating packets in a vacuum sealer bag - suck the air out so that the desiccator can focus on actual moisture. or am i out in left field on this one?
Water damage is one of those “if you need to ask, you can’t do it” kind of repair. Leave it to the professionals.
