In this case, I think you're generally a problem with the software, right?
The problem with the lattice machine software can definitely be solved!
There are 2 types of lattice machines:
1. Soft grid: enter * on the mobile phone, after which you are required to enter the lock code, the initial password is: 12345, if you have changed the mobile phone password, that is the changed password (not the SIM card password), and then a white screen appears, only the word nokia is displayed, 2 3 minutes after the grid is completed, re-enter the time;
2. Hard grid: turn off the computer first, and then press and hold the dial key, "* key, and "3" key when turning on the computer, and turn on the power until the word "nokia" appears (you can't release any button during this process). Wait a few seconds until "formatting...... appears", then you can release the above buttons.
After a few minutes, the system format is completed, and the phone automatically restarts and enters the standby screen.
The above grid machine needs to pay attention: keep the power absolutely sufficient, do not try to shut down the grid on the way, can not plug in the charger, etc. Also, try to give priority to the soft grid. Your phone's C drive data will be lost. So you have to back up your book, information, etc. first.
No more, I think it's a hardware problem. Usually there's something in the upper left corner of the back of your main version that's small and broken. I don't know what it's called.
It's better not to go to kf expensive to die for!
Finally, I wish your little 7 a speedy recovery!
If there's anything I haven't explained, you can always notify me by text message.

Disassemble the phone's case, there is a row of lines on the top left of the display, press it to try. Something must have gone wrong over there.

It's good when it's white, don't try the software, it's 100% hardware.
Any idea why 100 bucks? Because it's to help you repair the line, it will take hundreds of mosquitoes to change the screen, big brother, and the repair line is unstable.
So practice often. It should have been changed at one time.,Besides,If it's not a screen.,Then you have to check it slowly.。 As long as the big item is fine, the hope is still big, and it is not expensive (of course, he may cheat you, open **).

Reinstall the system? Your phone just restarts with a white screen, and if it's not a hardware problem, you can fix it yourself.
100 pieces. It's better to call the JS merchant to die.
You grid the machine yourself (after the grid machine is not good, you can try to upgrade, there are tutorials on the Internet) press * for the soft grid machine (that is, like the computer system restore, restore to the initial state) The password is 12345

The white screen often has a white screen, because the program you open is too big, and the phone can't react at once, just like the computer crashes for a short time.
-
I also sometimes have a white screen. Maybe not as many times as you do, though...No phone has a loophole. Not perfect...If you really can't fix it, let's go and change it.
-
Either fix it again or replace it with a new one, but if you fix it, there will definitely be a next time.
-
You upgrade the version, you can upgrade it yourself. There are tutorials available online.

The white screen is normal, don't be slaughtered by kf.
-
The white screen is generally a hardware problem, and there are many problems with the LCD display chain silver defense screen.
Here's how to find out if it's a software problem.
1, turn off and turn on again, the ear bay is missing and listen closely, see if there is a boot of nokia**. If there is, it means that the software is fine. Bo Zheng.
2. After turning on the machine, press the keyboard close to your ear, if there is a key sound, it means that it is not a software problem.
3. After turning on the phone, dial 112, if you can talk, it is not a software problem.
If the above triers fail, you can only send them after-sales.

It may be a bug in the system, Symbian's system often has some such bugs, and the solution is to update the system with Nokia Software Updater provided by Nokia, and the new version of the system will be more stable. The software has ** on the official website of Nokia, please confirm whether the code of the mobile phone is the national bank or other systems with Chinese before updating, some parallel goods machines will have no Chinese after updating the Kaichazao.

If there is a problem with the hardware, it may be that the cable contact is poor.
The following is for reference.
1. The situation of white screen is the most common, it is caused by a bad screen, cables, IC and motherboard, depending on what causes the white screen.
2. In the end, the problem can not be solved, only bring your purchase invoice to the designated maintenance point for repair.
Point multi** operation, formatting.
The system thing, format (not back to factory settings) on the side of the machine, and it's fine. You can be specific. Let me add : >>>More
