Display discoloration, what causes display discoloration?

1 may be suddenly subject to electromagnetic interference, there is no problem, if it occurs frequently, pay attention to what interference sources are around, such as putting a mobile phone or something.

2 The display may be wet, or the screen may be static or magnetic due to continuous use for too long.

3 aging 4 hehe,The general color change of the display is the problem of the filter on the connection line between the display and the host (that is, the thicker cylinder at the line interface),When the problem first appears, it will change color when it encounters,And then it is often discolored,But it's good to touch the filter,It's not good to continue,It's best to change the line in advance,It's not expensive,Generally about 10 yuan is OK。

All of the above is possible

Oh,The general color change of the display is the problem of the filter on the line connecting the display and the host (that is, the thicker cylinder at the line interface),When the problem first appears, there will be color change,And then it is often discolored,But it's good to touch the filter,It's not good to continue,It's best to change the line in advance,It's not expensive,Generally, about 10 yuan is OK。

This is due to the fact that the display is in a humid environment for a long time.

or aging of the CRT.

You go to the computer and fix it.

Don't easily reach it because there is high pressure in it.

1.Demagnetize the display (if it can't be removed - the display degauss is broken!) )

2.Graphics card issue (it is recommended to reinstall the driver).

3.There is interference from a strong magnetic field around the monitor (text messages coming from the phone, etc.).

It is possible that the display is wet, or the screen is static or magnetic.

Color distortion, sometimes on TVs, if the monitor has an automatic degaussing function to remove it.

Demagnetize the display. Or go for a high-pressure bag.

Wrap the monitor, run downstairs and then run up to connect the cable.

Because according to the principle of optics, any color can be mixed with three colors: R (red), G (green), and B (blue) through a certain intensity ratio. These three colors are called triprimary colors.

And the display works according to this principle, the display is used R channel, G channel, B channel to control the color display, and once there is a channel problem, it will lead to the lack of a primary color no matter what color and produce color changes, because we are in the computer, most places are bright colors, that is, it is closer to white, for example, when you open the browser, the background color of the web page is mostly white, take white as an example:

Because white is a mixture of R, G, and B primary colors at the highest intensity, and the computer uses numerical values as (255,255,255), at this time, if there is a problem with one of the color channels, it will cause the change of the primary color to be missing, or weakened, for example.

If the blue channel is broken, that is, it becomes (255,255,0), the white will become yellow, and the whole screen will appear yellow.

If there is a problem with the green channel, i.e. (255,0,255), the white becomes purple and the screen appears purple.

If there is a problem with the red, it will appear sky blue.

If there is a problem with both, such as red and green, the screen will appear blue.

However, the general channel problem is caused by the poor contact of a certain part, virtual welding, which is why sometimes you use your hand to pat it and it will get better, because the vibration generated by the slapping will make those parts that are not in good contact again.

Some monitor discoloration occurs after being turned on for a while, then comes back after a while, and then changes ,...... after a whileThis situation is because of the poor contact, the resistance at the contact point increases, a lot of heat will be generated, and the contact point of the part will be completely separated due to thermal expansion and cold contraction, resulting in circuit breaking, so that the channel stops working, causing the screen to change color: then because the contact point is separated, no heat is generated, the contact point begins to cool, and the contact point of the part will heal the contact point again due to thermal expansion and cold contraction, the channel will start to work again, the screen will return to normal, and then ...... againAnd so on.

If there is a discoloration of the display,Generally shake a few times will recover,If you're lucky,Will shake the place of the virtual soldering to the right position,And then there will be no discoloration for a long time,That's how my monitor is,Good luck last time,It hasn't changed color until now,It's just that I don't dare to touch the monitor anymore.,Wait for a touch and then there will be a problem pulling。

But I still recommend taking it to a repair shop to repair it,Generally, those who repair TVs will repair it,If you're a CRT monitor,If it's LCD,Then you have to take it to a place that specializes in repairing monitors。

What kind of display are you using, is it CRT or LCD, if it is CRT, it may be magnetized, degaussing is OK,

CRT, right? There is a circuit board on the back seat of the picture tube with virtual soldering.

I don't know if you're talking about CRT or LED, but it's not the same.
