Computer LCD monitor, full screen TV and full screen game playing white screen

I have the same problem as you, the power board and the driver board have been replaced, and it's still not good, they told me that the screen is broken, I don't believe it, it can light up the white screen, indicating that the LCD is good, and then take it to a more professional computer city to repair, people get it in 20 minutes, it's a small part of the screen circuit is broken, that is, the circuit board of the liquid crystal wrapped in tin foil behind the screen, many of the miscellaneous armies outside can't fix this, and they don't dare to disassemble it, and they know that they can change the two boards, which can be done by everyone, A little deeper will not be, blindly delayed the effort, and almost tricked me into selling the monitor for 100 yuan. Therefore, he still has to go to a professional place to repair the computer, so as not to waste time and money.

It is likely that there is a problem with the propulsion capacity of the voltage converter he replaced for you. When the output power is increased, it has insufficient pushing ability and the picture cannot be displayed normally. This is just speculation, so it is recommended to find a more professional maintenance master and ask him to help you measure it comprehensively.

It is recommended to bring your chassis with you when you send it for repair, although this output is standard, but it still depends on your actual situation to solve this problem.

I asked the experts of that company for you, and there are two possibilities in this situation, one is that there is a problem with the driver board circuit of your monitor or the power of the high-voltage strip is not suitable for your monitor. There is also a possibility that there is a problem with your graphics card's driver.

This is certainly not the LCD panel is broken, if the panel is broken, then the screen will be white no matter what mode it is, according to what you said, it should be the main driver board in the display or the reason for the high voltage bar.

It should be a problem with the driver board, and it is recommended to ask which master to find the driver board to replace it.

[Problem description]:

Web game black screen, white screen, IE caused by the inability to call up flash

Cause Analysis]:

When a flash game fails to run, the flash plug-in may not be called up due to the IE kernel. We tried to test the upgrade and downgrade of IE, and the following is the tutorial for IE upgrade and downgrade, [Easy Steps]:

Solution]:

One. IE downgrade.

explorer

explorer

Figure 8: Unloading IE8:

Figure 9: Locate the uninstall item and click Uninstall.

The Software Manager prompts you to choose to uninstall it anyway

The uninstaller runs automatically:

After the uninstallation is complete, select Do not restart, click Done, and the uninstallation is complete.

As soon as the computer opens the full-screen game, the white screen is a problem with the graphics card driver, and the method of reinstalling the graphics card driver is:

2 Run [Drive Life] and select [Recommended Driver], find [Graphics Card] in the list below (for other devices, just click on the corresponding device) and mark the box in front of [ ].

3 Then click [One-click Update], and click Restart immediately after the driver update is completed.

4 After the computer restarts, the driver update is complete.

It feels like the computer software is in a state of suspended animation.,You try to update the graphics card driver (you can use the driver wizard or drive life) to upgrade the next DX9.If it doesn't work, reinstall the system. I see that you have a 360 security guard There is a reinstall system option in it, (find it yourself, if there is a problem, I am not responsible haha.)

Set the resolution, if you play full-screen games, it's best to set the split screen ratio to the lowest, about 800x600.

Right-click on the desktop - Properties - Settings - to minimize the screen resolution.

Has it been blocked by security software?

First, if you disconnect the monitor from the computer, the monitor will normally show no signal. This shows that your monitor is good.

Second, you connect the machine to another machine to try it out to see if the monitor is broken or the host is a problem.

Third, determine whether your graphics card driver is abnormal, you can reinstall the graphics card driver Fourth, if the display is good, and the graphics card driver is normal, then you need to confirm whether there is a problem with the graphics card or the motherboard.

Either it crashes, or the graphics card is broken, or the graphics card power does not support the game parity.

Do you have integrated graphics or discrete graphics?

If it's an integrated graphics card, then you want to want to block it immediately and change it to a discrete graphics card, if it's a discrete graphics card, there are several possibilities:

1. The graphics card is good, but the CPU and memory modules can't keep up, but this possibility is very small! Because you used to be able to use it!

2. Have you reinstalled the system, and it is a higher system, such as or above the version, if you install it, congratulations, it is actually easier to solve, the reason is that the higher the version of the XP system, the newer and higher the driver it comes with, and when you reinstall the system, a new driver (the latest) will be automatically installed, instead of buying a graphics card with the driver, so you can't play the characteristics of the graphics card! If you have installed the most original driver, then you should pay attention to the computer prompt during installation, such as "the current computer thinks that the driver is newer than the current installation, whether to stop the installation" The general subconscious point is "yes", but in fact, it should be clicked No, so many people will make this mistake when installing, and there is an installation error, resulting in the system hardware can not play or the system crashes!

3. The newly installed game driver is compatible with the computer department, it is recommended to reinstall the graphics driver!

4. Clean up the dust, please don't underestimate this work, it is also possible that the dust accumulates on the slot, resulting in a poor connection between the hardware and the board, but once there is a problem, the small machine is slow, there is a blue and white frequency screen, and the crash, and the hardware says goodbye to you

Good luck!

A problem with the game itself.。。 Or the game requires some configuration like Direct X or something.

Try reloading the game, it should be a game problem.

The white screen failure of the LCD LCD display may be caused by the LCD panel drive circuit problem, the LCD panel power supply circuit problem, the screen wire contact poorly, the motherboard control circuit problem, etc. Since the LCD 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.

From the fault phenomenon analysis, whether the LCD 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 controlled by the switch, that is, the switching signal sent by the motherboard to the high-voltage generation circuit is out of control. Since the switching signal emitted by the motherboard microprocessor is generally controlled by several transistors, the fault may be a damage to the triode that controls the switching signal.

Fault repair ideas for the white screen of the boot display.

1. First disassemble the shell of the LCD display, 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 a 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 whether the output voltage of the DC-DC voltage conversion circuit supplying power to the LCD LCD screen is normal. If the output voltage is abnormal, check the fuse resistor, PWM controller, switch tube, inductance coil, filter capacitor and other components in this power supply circuit, and then replace the damaged components.

4. If the voltage at the output end of the DC-DC voltage conversion circuit is normal, there are damaged capacitors and other components between the output end of the DC-DC voltage conversion circuit and the interface of the screen line, 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 driving signal in the LCD panel drive circuit are normal. If it is abnormal, check the output signal, input signal and power supply voltage of the chip that generates this signal respectively to determine whether the driver chip is damaged. If it is damaged, it can be replaced.

Personally, it is recommended that if the white screen is caused by the display, it is best to replace it with a new monitor, after all, the display is also quite cheap now, and the IPS of large manufacturers like Asus, Samsung, and Philips is only 1,800 yuan, and there is no need to repair it again and again. Hope it helps.

1. After the white screen, press the numlock digital switch key on the keypad to observe whether the digital light of the keyboard responds normally, if it does not respond, it is sure that it is not a problem with the display; Otherwise, replace the monitor.

2. After determining the non-display problem, if there has been no black screen before, you can unplug the memory and remove the dust, pay attention to be sure to wipe the pins of the memory module, it is best to wipe it with an eraser, (I pinch it twice with my hand, and my hand is also skinny, hehe), if the symptoms are still the same, please see step 3.

3. Under the premise of observing the normal indoor temperature (extreme cold or extreme heat may lead to abnormal shutdown or restart), you can only replace the test one by one by the elimination method: power supply (considering the power size), motherboard (use time), hard disk (file allocation table link error or bad sector), sound and graphics card, and other ......

In the end, I can only wish you good luck.

There are three main reasons that can cause a white screen. First, the screen line falls off. This happens when the display is always white.

Second, the screen circuit board is fused. The reaction on the screen is also always a white screen. Third, the fault of the screen power conversion circuit is the DC-DC circuit, and sometimes there is a short display or no display and then a white screen when the fault occurs.

Judging from what you said, it should be the third one. It is a failure of the screen, but it is a non-fatal failure.

If the logic circuit board fails, send it for repair!

1. Check the software problem first, reinstall Adobe Flash Player, uninstall and reinstall with 360, don't install the beta version to install the official version, if you can't reinstall the system, if it doesn't work, consider the hardware problem.

2. In terms of hardware, there are three common reasons for white screens, first, the screen cable is damaged or the contact is not good, second, the screen itself is damaged, and third, the motherboard has a problem supplying power to the screen or the graphics card chip is caused by virtual soldering.

In terms of hardware, it is recommended to go to the original repair point for repair.

Is it that you can still watch it when the jujube is not sold on the full screen, and when it is full screen, it becomes a white screen, but there is a sound?
