Fixing a magenta Screen

This is for a Samsung Galaxy S3 (i couldnt choose that model). Id been having some screen issues with my screen not wanting to respond off and on for sometime. But yesterday I had put my phone in my sons stroller and there was a very lil bit of seiarra mist on the bottom. I didnt realize it but when I checked the phone the charge port was dry and the liquid damage indicator hasnt changed. Well my hone was working for a few hour after. I gave my phone to my husband to hole and when i took it back and tried to unlock the screen it turned magenta. I cant see anything. I pulled battery and restarted the phone that way. Still magenta. The phone itself sees to work as it booted and indicated I had an email even tho I couldnt see anything. So I put it in rice jus to see what would happen. My husband put it together and it came on normaly (showed the samsung screen) and went magenta again. What in the world is going on and how do I fix it?

Water Itself is not damaging to the board. water in it's purest form is non-conductive. the actual problem is the minerals in the water. (Iron, Calcium, Sodium, Lime) These are conductive and cause damage. unfortunately, they have a much higher boiling temperature than water, so when the water evaporates, (Sped up by the rice) these minerals are left on the motherboard. Rice doesnt actually help the damage, but rather speeds up the drying porcess. If the phone functions WITH the rice treatment, it would have worked without the rice treatment.

as a water damage repair, it still is only 50/50 as to whether or not you can get the device up and running. follow the next steps, andyou may have a functional device.

1) Isopropyl: Take a 99% rubbing alcohal, also known as Isopropyl, and a toothbrush. (New, as it can not be previously contaminated by conductive materials such as saliva, or tap water) soak the board in the isopropyl, and scrub diligently. make sure not to be terribly rough on the board, but still use a heavy handr

Check to see if board works

2) DeOxit (Electronics cleaner): I have used many brands, but DeOxit is the the one i have had the most success for, so i suggest this brand. others may work, and it is only a personal preference. spray the cleaner onto the board, and seal in a tupperware container. let sit for an hour, then re-soak with isopropyl to dilute any lifted dirts, and scrub with the tooth brush. Essentially, after the DeOxit has sat, Repeat step one.

Check to see if board works

3) Sonic Wash: This is implying you have access to the tool required. usually need a repair shop environment to have one The sonic wash is a tool, usually cosing between 300$-500$. fill it with distilled water and a liquid electronics cleaning solution. this pulses the cleaner underneath components where a brush can not reach. though this is the most successful procedure, it is also the most expensive of the three.

i hope this helps, and if it does, please accept the answer.

4) After all of these procedures, if any funtions aren't working, try replacing the modular component that the function is related to. (Antenna's for signal, Charge port for charging, Camera for camera function, ETC.) There is a high probability that your screen has suffered corrosion damage, in which case you would need to replace it.

Anything further than this will be a board level failure.
