The Nokia N72 fell into the water 20

It's better to fix it and don't dismantle it yourself.

First of all, after picking it up from the water, never turn it on, take the battery off immediately, remember not to press a button, dry it with a hair dryer, blow it slowly, don't rush, if you don't disassemble the machine, for the sake of insurance, dry it for a few more days, it's fine.

First of all, congratulations, the common sense is too powerful, and you dare to turn on the machine when you get into the water.

Admire. And then I'm going to tell you: just change the machine.

I advise you to go to customer service to fix it.

You can't turn it on right away when water is ingressive...

To remove the battery directly! Then take the blow blow!

My ** also fell into the water some time ago, it was a big bucket of water... Later it was good.

In your case, I guess the motherboard is burning

I don't know if your ** has passed the warranty period, if it is very expensive when you go to KF, you can also choose the place where the mobile phone is repaired in the general area to take a look, I hope the motherboard is not broken

Good luck!

Hurry up to customer service to repair.

If it is delayed, the motherboard will be broken if it burns.

Go to KF! It doesn't matter how much water you're in! The first thing is to take the board directly! Don't press any keys! ``

Looks like yours is the main version burned! Silence! ``

If you turn it on right away, it is possible to burn off the motherboard....If there is no problem with the motherboard, go to the store and ask for about 20 yuan.

Take it to repair, and dare to turn on the machine if it gets into the water.

If the motherboard doesn't burn, remove it and wipe it with a potion.

Not much. If you burn .........

Pray! It's time to change your phone!

Immediately remove the battery, do not press the shutdown button, and then dry it with a hair dryer, it's OK, if it still doesn't work, find customer service, you may have to change the main version.

Water ingress and crashing are the two taboos of mobile phones, and water ingress is particularly serious. According to an engineer from Guoxin, after the mobile phone gets into the water, the first thing to do is to turn off the power, of course, not to press the shutdown button, but to remove the battery. Because as soon as you press the shutdown button, the hand-held shirt machine will be powered on, and it is likely that a short circuit will occur, causing damage to the mobile phone, and then send it for repair as soon as possible.

If the warranty period of the mobile phone has expired and you don't want to send it for repair, you can boldly disassemble the phone! Wipe the parts of the phone with a tissue, and then blow it with a hair dryer for a few minutes, in order to ensure that all the internal parts are dry, it is advisable to air dry the phone for a few more days before you can turn it on again.

Once the mobile phone gets into the water, the battery should be removed immediately, and it must not be turned on immediately to understand the condition of the mobile phone. After removing the battery, do not use a hair dryer to deal with it, and immediately send it to the repair professional to disassemble the machine for water treatment, such as falling into sewage or corrosive liquid, and use ultrasonic cleaning and drying before proceeding to the next step of maintenance. If the mobile phone can still be used after water penetration, it should be sent to a professional to deal with it to avoid corrosion of the circuit board and make it impossible to repair.

No matter what kind of water the phone falls into, you should first remove the phone battery and no longer power the phone. If it falls into clean water, remove the battery and clean the phone with anhydrous alcohol, because the alcohol volatilizes quickly, and the water on the circuit board can be volatilized together. Then use a heat gun or hair dryer to dry the circuit board, and then power up the test machine, and most mobile phones will work normally.

If it falls into the sewage, it should be cleaned immediately, and the dirt that can be seen should be cleaned first. Use a brush to brush off the impurities attached to the pins of the components. Then, the circuit board is scrubbed with an alcohol cotton ball, and if the pollution is serious, the impurities must be vibrated out with the help of an ultrasonic washing instrument.

Then use an air gun to dry the circuit board, and then repair all the chips.

Blow dry and see if it still works.

1: No matter what kind of water the phone falls into, you should directly remove the phone battery (instead of pressing the power off button) as soon as possible!

2: Use undusted napkins, cotton balls, cotton swabs, etc. to absorb all the water that can be wiped off outside.

3: If it falls into clean water, you can clean the phone with anhydrous alcohol, because the alcohol volatilizes quickly, and the water on the circuit board can be volatilized together (provided that you have anhydrous alcohol). If it falls into the sewage, it should be cleaned immediately, and the visible dirt should be cleaned first, and the impurities attached to the components should be brushed off with a brush.

4: Use a hair dryer to swing the dryer from a distance. (Be careful not to blow too close or to one place for a long time).

5: Keep the phone in a cool and dry place for 24 hours, if there is no hair dryer to dry the water, it is best to leave it for 48 hours.

6: Install a battery with sufficient power to test it, if it can't be turned on, then you have to take it for maintenance. Good luck to the landlord!

Immediately remove the back cover, remove the battery, and dry it or dry it with a hair dryer cold air.
