half of my 5s fell on a water/oil mixture, it already had a problem with the battery even before that. and i completely dried it off from water. however there’s oil inside the screen, and the phone charges (it shows the battery thing) but does not open. can i still have this repaired?
You’ll want to decontaminate the logic board. If you want to try this yourself: Open your phone and remove the logic board (follow this guide)Inspect the logic board, especially around the connectors and look for corrosion.Inspect both sides of the board. Unfortunately, most of the board is covered in shields. That’s usually where the damage is occurring.Put your board in a container with >90% isopropyl alcohol and let it sit for a while.Use a soft brush, like a toothbrush and lightly brush away any corrosion you see.Rinse in alcohol and repeat.Let it air dry for a day.Re-assemble and hope for the best. A professional repair shop that does water damage repair may be able to recover your phone or the data because they have access to pro-level ultrasonic baths and specialized cleaners as well as the skills to troubleshoot your board. Many shops have a no fix/no fee policy so you don’t have to spend money to find out if the phone is fixable or not.
