How to solve the problem of blinking on the open web screen

Failure Phenomenon:

1, the screen edge has flashing phenomenon;

2, the whole screen has flashing phenomenon;

3, a corner of the screen has a flashing phenomenon.

　The misunderstanding of the fault point:

Many people think that this is the power supply voltage is not enough or unstable caused by some "master" may even be said to be due to some electronic ballast or electromechanical electrical appliances to bring the interference of the color display power, some people say that the video card has been caused by hardware failure. In fact, these views are wrong, because the display of the voltage requirements are not very strict-most of the current color display can be in the 100v~240v power supply voltage under normal work. Of course, if the voltage is too low or the voltage fluctuation is too large, it is another way to recognize, however, in the past two years, the national implementation of rural power grid reform has already begun to take effect, has fundamentally solved the past rural voltage instability, low voltage problems, and in the city these problems are usually not exist, So these factors are no longer important. As for other electrical appliances will cause interference is even more impossible, after all, color display is not a mutual inductance voltage-stabilized power supply, and other appliances even if the interference will not be screen flashing!

Failure reason and countermeasure:

The real fault causes of the first two kinds of fault phenomena are usually caused by the virtual welding of some components of the line circuit or the decrease of the capacitance capacity of the +300v filter at the power source. The latter is not likely to be high--only in individual models and in the case of a more severe loss of capacity, the human eye can discern the flicker. In addition, some models of the video-powered part of the circuit is relatively special, sometimes the part of a component of virtual welding can also cause this fault phenomenon. Of course, if you set your monitor's resolution and refresh rate too high or too low, you can also cause this type of failure, so you can set the resolution and refresh rate to the middle value try (note: Long working in overclocking state will make some components aging and this failure, and the fault point is more difficult to find). There is a bug in the driver for the video card or monitor, so you have to try updating the driver first. If none of the above processing is valid, you can focus on whether the high voltage and high voltage generated by the high-pressure package are normal, because sometimes these two voltage anomalies can also cause such phenomena. Note: If you turn on the TV there are flashes, it is necessary to check whether there is a problem of mains power supply-such as too small capacity or excessive voltage fluctuations, etc. (it is best to find an electrician to check).

In general, the maintenance of such a failure requires you must have some hands-on ability and professional knowledge, so I suggest you if you eliminate the simple cause of failure after the repair of the delivery of Electrical maintenance department to deal with.

Sometimes some magnetic items (such as some low-end power box or ADSL external cat power supply, etc.) placed near the monitor will cause a certain corner of the screen flashing, so encountered this phenomenon to first try to clear the display around the objects to see, usually the problem can be solved.

　　Question two: What to do when you open a web screen flicker

Many friends use the computer to browse the Web page, a browser, the computer's monitor screen will blink, this situation how to solve it? In fact, it is very simple, the general appearance of the computer, the monitor is CRT, LCD monitor does not have this problem. So in this problem, you just have to adjust the refresh rate of the monitor. Generally tuned to about 80 Hz, as long as the display at 75 Hz will not flicker. The method for adjusting the refresh rate is as follows:

First, the right mouse button click on the desktop blank out, and then select the property options.

Then, in the Properties dialog box, open the Settings tab, and click on the Advanced button below.

Finally, open the Monitor tab in the pop-up dialog box and select the frequency in the check box below.
