My Nokia 5230, after being dried, was used normally, and I used it for a few days. 50

Your civil drying method is incorrect, and most people will think that it can be used normally after drying, but otherwise. First, there is corrosion in the circuit and hardware of the entire motherboard, second, the display screen may enter the water (or there is water behind the screen, this is one of the reasons for the blurred screen), when you dry the power on (boot) it will cause a lot of hardware small devices to short circuit, a long time, there will be the situation you said. Now it is recommended that you remove the battery and go to the maintenance department to repair it.

Maybe clean the motherboard professionally, and then change the display screen is OK.

This problem occurred in my mobile phone at the beginning of this year, I went to Nokia customer service center to consult, they helped me identify and said that it was not man-made damage, so they gave me a free replacement screen, mainly within the warranty period! If you know your customer service address and it's within the warranty period (not within the warranty period or artificially you have to spend 200 300 yuan to change the screen),Just go over and change the screen,But it may also be other problems,They will find out the reason when you go there,And the situation of the screen seems to be very common in this machine,They also know it....Good luck! The general manual or warranty card shows the address of the Nokia customer service center in each province

I think it's the display interface corroded, and it can't be ruled out that the CPU also has a problem, where are you? If you want to repair it, look for me, but the problem is that the former is okay, and the latter has no value for repair.

This... For precision electronics... If there's a problem with the motherboard, it's a whole motherboard.

So there is no need for the landlord to be entangled in the motherboard** problem...

Same as mine. 3 solutions.

1. Install magnets, you can do it yourself, pay attention to protect the screen can not be forced, the magnet can start from the headphones, so easy to find, also small, it is estimated to polish it, I have been grinding all morning, anyway, I have nothing to grind at work. Do not burn because it will demagnetize. Grinding to about 2 mm thick,,, the phone can be picked open from the volume button, cut down, a little tight below, pay attention to the top, there is a cable.

It is recommended that you do it when the screen is blurred, and put the magnet under the earpiece when the screen of the mobile phone is blurred. If the screen gets better, don't move it.,Just put that.,It's not good to move to the right.,It's not good to be on the opposite side of the magnet for a long time.,Test it again.。 Until good.

The screen has become better, don't be in a hurry to install it, press the unlock button to test a few times, everything is ok, install the phone, and play **Test whether the distance sensing has any impact, this problem occurred when I installed it. If there is no problem, open the phone again and use the quick-adhesive glue to firmly top it, remember, don't install it too low, it will break the paper on the screen, mine is, press it to break, I changed the screen.

2. Change the screen, I changed it for 210 yuan, not the original, because I am close, you can find him if there is a problem, you must be optimistic about changing the screen, don't be fooled. Last time that person took an old one,,, the screen cable I changed was golden.,It's said that this won't spend.,My previous one was white.。 Sure enough, there are no flowers since then.,I suggest you change the golden line.,It's just a suggestion.,Will you spend it or can't find me.。。

I suggest that you let the phone cool when you change the screen, test it when you install the screen, and put the phone on the counter to let him cool for the test. Multi-swipe unlock test...

3. The third is only to keep the phone cold. . .

4·· It's so hard to type, give it the best, haha.

It has nothing to do with the weather! It's estimated that the screen is broken.,Xiao Wu Bar is all this problem.,During maintenance, he said that you squeezed or pressed the screen...

It's normal to have a flower screen occasionally, don't worry, try not to let him catch a cold when it's cold, I'm also 5800

Remove the ** card and memory card and throw it in the trash.

Mine is also in this situation.,There's no way to hear that it can't be completely solved if you change the screen.,Some say brush system.,I haven't tried it.。 It can only be used again after the heat is hot, and today my 5800 is at minus 7 degrees in Tianjin, and it will be good to put it in my arms for a while. Make do with what else can a machine at this price ask for, how difficult it is for the Chinese to defend their rights, hey endure it.

This is basically concluded in the process of online master communication,Almost more than 80% of the problem of the screen comes from hardware。 It is said that it is caused by a defect in the power supply circuit on the LCD screen cable.

Let me tell you about my history of blood and tears to solve this problem.

I'm 5233.,It's also a flower screen.,If it's not too cold.,Unlock 10 times and spend 6 times.,It's cold and basically the whole screen can't be used.。 At first, I thought it was a software problem, but I found a variety of methods on the Internet and it didn't work. Later, by chance, I got off a Nokia's ovi suite, and I wanted to listen to a few songs, (I'm licensed) after I connected it, and told me that I could upgrade, and I was idle anyway, so I gave birth to it.

After automatically restarting it n times,—— it didn't take any longer! (Occasionally, I will spend a little, but after all, I don't spend it). I thought the problem was solved, but the good times didn't last long, and it took half a year, and it took again, and it took a long time to unlock it with your hands to occasionally not spend.

Just when I wanted to give up completely, I saw a new method on the forum, so I found a small magnet and placed it in the blank space between the earpiece and the screen, and it worked miraculously. It doesn't take at all. Later, I got bored, so I laughed at the little magnet and stuffed it in the corresponding position in the machine.

It has been used normally so far.

The above is my hard work word by word and blood and sweat, I believe that I can solve more than 8 percent of friends who encounter similar problems, I hope to help you.

Actually, it's all a minor problem! If you're brave, just remove it and put a magnet on your own! I just tried!

ok!If you don't worry, just find a bad earphone, get a magnet and put it in the middle of the screen to see if it works, and then disassemble it! The other gods and horses are floating clouds.

This method only works when the weather is cold.

This has nothing to do with the power supply of the mobile phone, and the temperature has nothing to do with it, mainly the screen line and the two major parts of the screen, the screen line may also be loose (you can also open it with a hair dryer and blow it a little if you have the ability to do it) If it is a full touch screen, it is recommended to take it to the maintenance point to repair the easiest way to blow it directly with a hair dryer The temperature is not too high and can generally be blown well).
