Why is there a black spot on right corner of screen and some lines?

Hi! So my brother spilled some juice on my iPhone and now I have a black mark in the corner of my screen, and some lines that are brighter than rest of the screen. I will provide you pictures of it in the next links. Please, help me fix that, I really need this phone. It is currently in rice.

First of all, your screen is damaged and will need to be replaced. You can follow this guide for a DIY repair.

More importantly, your phone has sustained liquid damage. Not only does rice not do anything to help this condition, it actually makes it worse. Because your phone is still “working”, you probably don’t have a lot of liquid inside but if you do nothing to address the issue, you run the risk of having issues later on. I would do the following:

  • 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. You can peel away the black cloth shields on the back of the logic board for a proper look.
  • 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.

I would still open it up and make sure there is no liquid residue on the phone internals.

Hello @acimicc,

The screenshots you took look like your screen has “dead pixels“, a term used for pixels that do not work as well as the others. You will most likely need a new screen. IFixIt is selling one with all the tools you need to replace. Find it here.

If you need any help please reply to this answer.

Thanks,

John
