Note 5230 black screen problem, my 5230 black screen won t turn on. Ace in, thank you!

It is possible to burn the screen, but the landlord can try to save himself first.

The first thing to do is that water ingress and crashing are the two taboos of mobile phone use, and water ingress of mobile phones 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 mobile phone 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 your phone's warranty has expired and you don't want to send it for repair, you can boldly take it apart! 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.

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 hair dryer or hair dryer to dry the circuit board, and then you can 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, scrub the circuit board with an alcohol cotton ball, save yourself, and if it still doesn't work, take it to repair, good luck to the landlord!

Know that the team of Steel Seven Company will answer for you! Thank you.

Yes. Just go and change it.

If you have already tried it according to the above method, you can send it to the after-sales service station. It's generally a problem with the software, and the service station just brushes it again. It is free of charge if it is under warranty.

It may be poisoned.,Hard grid machine.,Red and green keys, and the camera power is pressed together to be a hard grid machine.。

I was like that the day before yesterday, but that's fine.

Mine is also a problem with the phone these days, and then sent after-sales. There are a lot of them in the aftermarket"Expired"users! If you change the hardware, you will have to pay (depending on what you need to change)!Software doesn't, even if it's flashed!

There are two types of black screens: one is standby black screen; One is the black screen in use (the black screen in use can also be understood as a crash). Most of the black screens in use occur on their own ** third-party software, and this situation rarely occurs with the machine.

It can also be subdivided into two kinds: one is that there is a problem with the software itself, the software itself is unstable, or it does not match the mobile phone system, etc., this is easy to solve, just uninstall it; The second is the conflict between the software and the software, this solution is a little more troublesome, and it requires a software to take a software to install and uninstall the software in the experiment. If you find the uninstall problem, it can basically be solved.

Here it is recommended that you do not install too much useless chicken rib software. Although buying a smartphone is to play the machine. But some software that you don't use at all is a waste. Just install some software recommended by friends in the altar.

Most of the straight board machines have a power-saving circuit design: the mobile phone will automatically turn off the screen if it can't detect the key trigger signal for a long time. When you need to use your phone, a button will activate the power-saving circuit. Then the screen lights up!

The reason for the black screen is that the screen triggers the circuit delay reflection. That is to say, the mobile phone system has issued a command to light up the screen, but due to the delay of the circuit, it was not sent successfully, and the result is that the screen is not lit successfully. But the phone system thought it was already lit. So there is the problem of black screen.

You can give it a try. The phone screen is black, don't be in a hurry to restore it first. Use a friend's mobile phone to call your own **, if you can get through, you can also answer normally. That's basically the problem.

There is no need to panic when a black screen appears, and there is no need to pick the battery immediately. You can leave the phone for about 3 minutes without pressing any keys on the phone, and then press the button again to activate the screen. After many years of practice.

It can generally be returned to normal immediately! In this way, it basically does not have a big impact on the use.

Although it is very annoying to have a black screen frequently, it seems that there is no solution to the black screen completely. So I can only endure it with my pants.

It is estimated that if you want to completely solve this problem, you can only wait for Nokia to upgrade the version again.

Normal ......If it's too frequent, just check the machine, you won't be able to search, Nokia grid machine.

My c5 and 5230 are like this, often rebooting after a black screen... It is estimated that it is a common problem with the Nokia S60 third and fifth version systems...

The time delay is normal, but some are shorter, and some may be longer.
