Phone not powering up - some water damage


My IPhone 6 encountered some water due to a leaking water bottle in my bag. Initially the phone continued to work fine. Then vertical lines started to appear on the screen and finally the screen went completely dead. And I could not boot up the phone anymore.

I opened up the phone and was some corrosion near the home button connector and the front camera connector. Other than that, most of the chip looked pretty clean. I went ahead and did the brushing and cleaning with isopropyl alcohol. But the phone still would not start up.

How can I test the board to see where the problem might be before I spend money buying a new battery and LCD/digitizer?

Thank you.

Hi Kareen. Unfortunately, 80% of the electronics is hidden underneath the shields. That is where your problem probably resides.

If you don't want to spend money buying parts to troubleshoot, then I recommend you find a shop that can do water damage and micro-soldering repairs. They will properly diagnose your problem.

If you do want to try things, start with...

  • Is your phone recognized by iTunes if you plug it into your computer with a lightning cable?
  • Have you tried a hard reset (home+power until the Apple logo)?
  • Have you tried DFU Mode?
  • Inspect visually the area around the screen connectors. Use a magnifying glass or preferably a jeweler's loupe. Look for missing components or loose solder joints on the connectors (on the logic board and the screen flex cables).
  • Do you have access to another iPhone 6? If so you could try to isolate some variables. Like put in a known good battery or try your battery in another phone.
  • Order a battery and or a charge port and try replacing those. Please follow iFixit guides very carefully and keep track of your screws and where they go.
  • You could try a screen but f iTunes doesn't recognize your phone, it's not worth it.

There are lots of things to try but once you get to soldering issues, it really isn't a DIY fix anymore.
