A white screen appears after the desktop computer is turned on, and it will be normal again after a

Generally, most of the white screens are problems with the motherboard.

Possible causes.

1. Caused by bad screen wiring.

2. There are also IC causes.

3. Water ingress and breakage can also be caused.

You will need to bring your purchase invoice to the designated repair point for repairs.

Possible causes.

First of all, your configuration has not come up, it is estimated that it is related to your graphics card, and you need your detailed computer configuration.

It's not normal, there's something wrong with the LCD driver board!

The main reasons for the white screen of the monitor are:

1. The internal problems of the display mainly include: LCD screen drive circuit problems, LCD screen power supply circuit problems, poor contact with the screen wire, and problems caused by the motherboard control circuit.

After the LCD screen is turned on, the white screen shows that the backlight and the high-voltage generation circuit are working normally, but the LCD screen does not get the drive signal. If the screen disappears after shutting down and then turns white again, it could be an issue with the power panel.

2. The screen that displays white may also be touched or damaged by the graphics card or graphics card cable.

3. Since the switching signal sent by the motherboard microprocessor is generally controlled by several transistors, the fault may be that the triode of the control switch signal is damaged.

The white screen fault of the LCD display may be caused by the LCD panel driving circuit problem, the LCD panel power supply circuit problem, the screen cable contact poorly, the motherboard control circuit problem, etc. Since the LCD display screen is white after turning on, it means that the backlight and high-voltage generation circuit are working normally, but the LCD panel does not get the driving signal. If the screen disappears after the laptop is turned off, and then the screen is white again, it may be caused by a problem with the power strip.

1. The fault of the computer white screen may be caused by the driving circuit of the computer panel, the power supply circuit of the computer panel, the poor contact of the screen wire, the control circuit of the motherboard, etc. Because the computer has a white screen after booting, it means that the backlight and high-voltage generation circuit are working normally, but the computer panel does not get the driving signal. If the screen disappears after the computer is shut down, and then the screen goes white again, it may be caused by a problem with the power strip.

2. As long as the computer is plugged in, the high-voltage generating circuit is always in working condition, and the backlight is always lit. In other words, the high-voltage generation circuit is no longer controlled by the switch, that is, the switching signal sent by the motherboard to the high-voltage generation circuit is out of control. Due to the motherboard microprocessor.

The switching signal is usually sent through several transistors.

to control, so the fault may be a damage to the transistor that controls the switching signal.

There is a poor contact between the needles at both ends. It is recommended to ask a professional to check it, otherwise it may become more and more serious in the future.

1. The situation of white screen is the most common, which is caused by a bad screen, a cable arrangement, and an IC. Water ingress and falls are the most common, depending on what causes the white screen.

2. Generally, most of the white screens are problems with the motherboard.

3. There is only one way: bring your purchase invoice and go to the designated maintenance point for repair.

You try not to pull the data cable, turn off the monitor switch, and see if the white screen can also become normal, and if it can also become normal, then it is a problem with the display.

I think you have a problem with the data cable, the contact is poor, go outside to fix it, it's not very expensive, 40-80 is fine.

The generation of the white screen phenomenon.

Either the data cable is not connected. Or there's a problem with the cable.

Either the screen is broken.

Either there is a problem with the screen cable, and there is no problem with restarting it, so it is less likely to be a problem with the screen. It is estimated that it is a problem with the data cable, and you can choose it one by one.

2.The problems inside the display mainly include: LCD panel drive circuit problems, LCD panel power supply circuit problems, screen cable contact problems, motherboard control circuit problems and other problems.

Since the LCD screen is turned on after the white screen, the description. 3.From the analysis of fault phenomena, no matter whether the LCD screen is turned on or off, as long as the power supply is plugged in, the high-voltage generating circuit is always in working state, and the backlight is always lit.

In other words, the high-voltage generation circuit is no longer subject to switching.

The white screen of the computer is normal again after turning it on, why is this?

The problems inside the display mainly include: LCD panel drive circuit problems, LCD panel power supply circuit problems, poor screen wire contact, and problems caused by the motherboard control circuit and so on. Since the LCD screen is turned on after the white screen, the description.

3.From the analysis of fault phenomena, no matter whether the LCD screen is turned on or off, as long as the power supply is plugged in, the high-voltage generating circuit is always in working state, and the backlight is always lit. In other words, the high-voltage generation circuit is no longer subject to switching.

Oh my God, you've said a great job! Can you elaborate on that?
