Laptop screen white, laptop white screen how to solve

If the hand touches the monitor cover to recover, this situation is generally a poor contact in the hardware, the common is between the screen and the cable, between the cable and the motherboard, etc.

It is recommended to bring the notebook to the official after-sales inspection of the notebook manufacturer.

It may be a problem with the display or graphics card, or it may be a problem with the connection, try the external monitor, and it is normal that there is a problem with the screen or connection.

How to deal with laptop white screen:

After disassembling the screen frame, test the power supply of the screen and the voltage of each signal line on the screen cable socket in the power-on state.

If there is no disconnection in the screen cable, you can power on the test to see if the voltage of each signal line is normal after starting, and if it is not normal, check the relevant line.

If the voltage of each signal line is also normal, this situation is generally caused by the destruction of the screen itself or the lack of macro old color, and the LCD screen is replaced.

Common computer failures:

1. CPU temperature is too high and causes crash: The cause of this problem is most likely due to CPU overclocking, abnormal fan operation, poor heat dissipation installation, or uneven application of heat dissipation grease on the CPU base.

Then check whether the heatsink is installed securely, whether it is in close contact with the CPU, and check whether the surface of the CPU is smeared with thermal grease or whether it is evenly applied. Finally, if you have overclocked your CPU before, it's a good idea to slow down the frequency or do a good job of cooling the CPU, otherwise the CPU can easily burn out!

2. The fan noise in the chassis is large: In fact, the wind direction of the chassis is noisy, which is most likely due to the long use time and the fact that the fan has not been lubricated, which makes the fan shaft cover pin dry and has large friction. To solve this problem, we can solve it by simply adding some lubricating oil to the fan bearing.

Laptop white screen can be caused by a variety of reasons, here are some possible solutions:

1.Restart your laptop: Sometimes the white screen is caused by a problem with the computer software, try restarting the computer to see if it solves the problem.

2.Turn off and back on: Power off your laptop, wait a few minutes, and then turn it back on. This helps to remove dirt and oxides from inside the computer and improves power management.

3.Reset the BIOS: If your PC has a white screen issue, you can try resetting the BIOS.

Go to the BIOS settings, select the "Startup" option, then "Reset BIOS", and wait for the computer to reboot before trying to use the laptop.

4.Clean the screen: If you have a white screen issue with your laptop screen, you can try cleaning the screen. Use a clean cloth or cotton swab to gently wipe the screen to remove dirt and oxides from the screen.

5.Update graphics card drivers: If your laptop graphics card drivers are outdated or have issues, it can cause white screen issues. Try updating the graphics card drivers to fix the issue in Mongs.

6.Factory reset: If none of the above methods can solve the problem, you can try a factory reset.

Go to the BIOS settings, select the "Startup" option, then "Restore to factory settings", and wait for the computer to reboot before trying to use the laptop.

Please note that the above solutions may not be suitable in all cases, and the specific solution should depend on the laptop model and the type of problem. If the problem persists, contact a repair professional at 400-698-7786.

You can troubleshoot by following these steps:

1. If there is a connection problem with the monitor or screen, you can try to adjust the screen angle to see if it can be displayed normally.

2. Try to update the display adapter driver to the official latest.

3. If the latest system update or installation is caused, you can try to uninstall the latest installation.

Answer: The screen cable is damaged or not in good contact: the keyboard can be removed if the screen cable of the notebook is not in good contact, and the cable is generally hidden above the plane where the keyboard is located, and the cable can be repressed through the space removed by the keyboard.

2. The screen itself is damaged, and the motherboard has a problem supplying power to the screen: this is generally a problem with the power cord from the motherboard to the display screen or the screen is directly short-circuited.

3. Graphics card chip virtual soldering: Graphics card virtual soldering refers to the poor contact between the BGA solder joint of the graphics card chip and the motherboard, which is generally caused by the high temperature of the graphics card.

Note: The sleep switch of the machine cannot bounce normally after being pressed, and it will also cause a dark screen or black screen) Take a look.

Summary. Solution: 1. First disassemble the shell of the LCD screen, and then check whether the screen cable interface is loose or not connected.

After checking, the screen cable is connected normally. 2. Then turn on the power switch of the laptop, and then use the multimeter to measure whether the power supply voltage of the screen cable interface is normal. If the supply voltage is normal, go to step 5; If it is not normal, then check whether the fuse resistor or fuse inductor near the output of the screen cable is open or damaged.

If it is damaged, the damaged component can be replaced. 3. If the fuse resistor or fuse inductance near the output end of the screen cable is normal, then check the DC-DC that supplies power to the LCD screen. Whether the voltage at the output of the voltage conversion circuit is normal.

If the output voltage is abnormal, check the fuse resistor, PWM, controller, switch, inductor coil, and filter in this power supply circuit.

The laptop was broken by me.

If it is damaged, the damaged component can be replaced.

3. If the fuse resistor or fuse inductance near the output end of the screen cable is normal, then check the DC-DC that supplies power to the LCD screen. Whether the output terminal voltage of the voltage conversion electric circuit is normal. If the output voltage is abnormal, check the fuse resistor, PWM, controller, switch, inductor coil, and filter in this power supply circuit.

What to do. 4. If the voltage at the output end of the DC-DC voltage conversion circuit is normal, it is the active and damaged capacitors and other components between the output end of the DC-DC voltage conversion circuit and the screen cable interface, and the damaged components can be checked and replaced. 5. If the power supply voltage of the screen cable interface is normal, then check whether the timing signal and drive signal in the drive circuit of the LCD panel are normal.

If it is abnormal, the ruler fiber checks the output signal, input signal and power supply voltage of the chip that generates this signal to determine whether the driver chip is damaged. If it is damaged, it can be replaced with more hail.

First of all, we have to check what kind of reason it is.

This needs to go through the above inspection method to accurately know that it is the wrong parent.

This may be the need to go to the repair shop to test the pro.

This should be the display inside is made broken pro.

If you're satisfied.

Occasional white screen of laptops is a very troublesome problem, which may affect the normal use of users. If you are also experiencing this problem, then you can try the following methods to fix it:

1.Check if your computer's monitor connection is loose: Sometimes your computer monitor connection may be loose and your screen will go white, so try reconnecting the cable between your computer and your monitor to see if that works.

2.Check if your computer's operating system is updated: Some operating systems may be incompatible with your computer after an upgrade, resulting in a white screen issue.

So you can check if your computer's operating system is up to date, and if it is, try rolling back to the previous version to see if that solves the problem.

3.Check if your computer's memory and power are sufficient: Some computers have a white screen that can be caused by insufficient memory and power, so you can check if your computer's memory and power are sufficient.

4.Try restarting your computer: If your laptop occasionally has a white screen, you can try restarting your computer, which may fix the problem.

If none of the above solves the problem, then you may want to consider taking your computer to a professional repair station for service. Unrepaired by a professional can lead to bigger problems and even make your computer unrepairable, so it's best to take the risk of not doing it.
