6280 Splash Screen Failure, 6870C 0305A Splash Screen Fault

As long as it's not a software problem, just go directly to the Nokia mobile phone repair department. It's just a bit expensive, but it's absolutely reassuring, it's okay to repair it on Danfeng Street, but he will plant you, and there is no quality assurance, maybe it will be bad in a few days.

It may be that there is a problem with the screen cable, take it to the repair shop to see.

You try the grid machine, if it really doesn't work, take it and fix it. There are 2 types of lattice methods, soft and hard, with the soft one first.

1. Soft grid: enter * on the mobile phone, after which you are asked 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 machine 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 be noted: keep the power absolutely sufficient, do not try to shut down the grid on the way, do not plug in the charger, etc. Also, try to give priority to the soft grid.

3.It is to use stool to grid, if your phone has line 2, so you can keep line 2 after the gridThere is also a method that is the same as the soft grid, which is to restore the settings of the C drive at the factory:

Settings Game Phone Settings General All the way down to the last factory setting,OK,The default password is 12345,The effect is exactly the same as *,But the operation method is different。

If you have a font installed, you will need to delete the font in order to perform the gridFont file, that is, fonts Find c: system fonts, change the name of this file, and then delete this file, or install, this software is specially changed to c:

system fonts

Maybe the line inside is falling off, or maybe the cable is broken.

Don't push around with nothing to do.

Maybe the screen is damp, go fix it, or it's going to be a delay, and if you are in a hurry, you won't need to stop cooking.

It may be that the flashing machine is faulty, and it is brushed 1 from the new.

Principles for troubleshooting common hardware failures in computers.

There are usually some clues to a computer malfunction. The following principles should generally be followed for fault inspection and diagnosis:

1.Inspect the external parts first, then the internal components.

If the main unit or display does not light up, you should first check whether the switches, fuses, and sockets outside the machine are open or short-circuited, and then open the chassis or display for inspection after confirming that the external parts are normal. After opening the chassis, first observe whether the plugs and sockets of the system board are skewed, whether the resistors and capacitor pins are touching, whether the surface is burned, whether the chip surface is cracked, and whether the copper foil on the motherboard is burned. It is also necessary to check whether there are any foreign objects falling between the components of the motherboard and causing a short circuit, and you can also look at whether there are any burnt and discolored places on the board, whether the traces (copper foil) on the printed circuit board are broken, and so on.

In addition, pay attention to whether there is a burning smell in the host and board, so as to facilitate the detection of faults and the location of short circuits. At the same time, it is also necessary to monitor whether the working sound of power supply fans, soft hard disk motors or seeking mechanisms, display transformers and other equipment is normal. In addition, when the system is short-circuited, it is often accompanied by abnormal sounds, and the monitoring can find some hidden dangers in time and help take measures in time when the accident occurs.
