What should I do with the white screen of the Laptop?

The reason for the white screen of the computer and the general solution.

What is the white screen of the computer? The white screen of the computer is the fault of the white screen (white screen) after the LCD screen is turned on. This is the fault phenomenon of the white screen of the boot screen. Generally, the white screen phenomenon of the monitor is relatively uncommon. Appeared on some monitors that have been used for a long time.

The phenomenon of white screen is generally that the computer monitor has no image, and it is full-screen white. The main reasons are as follows:

1. The internal problems of the display mainly include: LCD panel drive circuit problems, LCD panel power supply circuit problems, poor screen line contact, motherboard control circuit problems and other issues.

2. The white screen of the display may also be poor or damaged contact of the graphics card or screen cable

White screen problem: The white screen of the LCD screen indicates that the backlight system is working properly and the imaging system is not working properly. The problem area may be destroyed by the LVDS chip, screen line or screen imaging system itself on the motherboard.

2.1 After the screen frame is removed, the power supply of the screen and the voltage of each signal line are normal on the screen cable jack under the power-on state. If not, check the relevant line.

2.2 If the power supply of the screen and the voltage of each signal line are normal, and the LCD screen is still white, this is generally caused by the destruction of the imaging system itself. You can use a normal screen to replace the original screen for further judgment. (The damage of the general screen imaging system itself is caused by the soldering or destruction of the LCD control chip.)

3. Release Power charge

Disconnect the host from the 220V mains (Note: the notebook needs to remove the battery at the same time), then press the main switch 3 times for 5 seconds each time. After the operation is completed, connect the mains and power cable to restart the test. Is the fault excluded?

Reminder: If the host has the possibility of entering the liquid, please do not operate to release the residual charge. The battery should be removed and sent to the service station for inspection.

4. Adjust the notebook screen angle

In the power-on state, adjust the display angle of the screen to see if the fault has changed or returned to normal? If it is possible, it can be used temporarily, waiting for the idle time period to contact the service station for further detection of the possibility of improper screen wiring.
