How to repair a water damaged cellphone

Almost all of us have cellphones and we take care of it because it has been a part of our daily life. But what will you do if your cellphone was accidentally dropped in water.

Here is my simple instruction on how to repair a water damaged cellphone using available and inexpensive mediums.

Things you will need:

1: Lacquer Thinner (which you can buy on your local hardware store)

2. Screwdriver (mostly a T6 screw driver for most cellphones)

3. Towel or piece of cloth

4. Paint brush or toothbrush

5. Blower or hair dryer

Procedures on how to repair the Cellphone

First disassemble your cellphone (you can request a blog from me on what model is your cellphone and I will make a blog on how to diassemble your model)

Next remove any sensitive parts like LCD, Camera, and other parts that the thinner solution will harm. most of them are plsatic materials

Next put the PCB board of your cellphone in a bowl and pour in lacquer thinner until the PCB board is totally submerged.

( lacquer thinner is the solution to be used because it dries quickly and it absorbs any moisture that resides on the parts of the board)

After submerging the board on the thinner wait for 5 to 10 minutes until the board absorbs the thinner.

Next, use your paint brush or toothbrush to clean the board. Do not use to much force while cleaning the board. Just enough force to just take off the dirt and moisture residue on the board.

After you clean the board thoroughly, dry it up with a piece of cloth and use a blower to dry it all up. Make sure that the board is totally dry before assembling the cellphone.

Then assemble the cellphone.

One way to test that the cellphone is not shorted is by using a tester. An analog tester is the best too; for testing. What you will do is put the dial of the tester on X1 resistance then put the Positive terminal of the tester to the positive terminal of the battery connector of the cellphone and the negative to the negative terminal of the cellphone. the needle should not move if the cellphone has no short circuit.

If there is no more short circuit in the cellphone, put the battery in the cell phone and its now ready to use.

Please request or suggest on this "how to" for me to serve you better.

Lacquer Thinner is too dangerous to use! It will destroy most plastics. Alcohol will do the same thing without damaging most plastics.

Затем необходимо нанять адвоката и выполнить определенные проверки на собственность. Хороший адвокат изучит не только физическое состояние туши, но и выполнение всех условий, указанных в договоре.

Hi, my samsung galaxy 1 fell into the toilet. The screen flickered wildly and I rinsed it after briefly with water, probably not a good idea. I then turned if off and put it later in rice. Initially the first black screen with Samung writing came on, but it wouldnot open any further to be usable. It also did not charge anymore. Is there any chance that I can repair it the way described above? Or get the data that is stored on it?

Kind regards
