The monitor has one side that is slightly red!

There are two main possibilities for a red screen on the display:

1. The inside of the picture tube. There are three electron guns in the picture tube, which are red, green and blue, and the three-color electron beam is fired to bombard the red, green and blue phosphors on the picture tube screen respectively to achieve the purpose of emitting light. If the cathode of the red gun and the ground part inside the picture tube are short-circuited (or leakage), the red screen phenomenon will occur.

However, if it works for a while, due to the high heat of the CRT filament, the electron gun has a slight deformation and gets out of the short circuit point, it can return to normal.

2. Outside the picture tube. There are red, green and blue three-way driving circuits (**amplification and output circuits) outside the picture tube, which drive the red, green and blue guns of the picture tube respectively. If the red ** amplification circuit fails, the working voltage of the red cathode drops, which can produce a color cast (red), and if the voltage drops sharply, the screen is full of red.

Detection: open the back cover, turn on, the red, green and blue three-point voltage on the sight plate at the end of the picture tube is generally about 130 volts, if the voltage of the red gun is low, then unplug the view plate, and the picture tube is separated, and then detect the red dot voltage, if the voltage is normal, then there must be leakage and short circuit fault inside the picture tube; If the voltage is still low, the external optoamp part is faulty. The common ones are poor white balance (as long as it is adjusted), ** leakage of the output tube, poor contact, etc., which are easy to deal with.

If it is an internal fault of the picture tube, it can be solved by electric shock, adding an independent filament power supply circuit, etc. But it is not recommended that you do it yourself, because there is high pressure inside, which is not safe.

Addendum: As long as the problem is not very serious, if it is within the warranty period, hurry up and replace it This is permanent wear and tear, which cannot be repaired. Also pay attention to the display must not put magnetic substitute things, remember

See if there are any strong magnetic items nearby.

If you confirm that there is none, please send it for repair. It could be a circuit issue.

Addendum: I told you that this phenomenon should be sent for repair, regardless of whether it affects the use or not. Because this failure may become more and more serious.

Don't put it off again and again for fear of trouble, otherwise it will be too late to cry after the warranty period. Also, the presence of a red border should not cause the electrons to break.

This is a quality problem, and it should be taken for maintenance as soon as possible.

There are times when one side of our monitor is red, what should we do? Let me give you a brief introduction to the causes and solutions of redness on one side of the monitor! Hope it helps!

Causes and solutions for redness on one side of the monitor:

The cause of the failure is caused by the green signal not being sent to the green gun of the image tube.

The location of the failure may be inside the display or outside the display.

For the outside, the main thing is poor contact. If you don't usually plug and unplug the display card connection plug between the monitor and the main chassis, try to plug it in and see if there is any change. If Wang Ji usually plugs and unplugs this wire plug, unplug it and observe whether there is a certain needle in the 15 pins in the plug***, the second pin is a green signal*** or multiple needles appear kneeling ***bending***retraction and rusting.

If so, treat the needles with Dalingqin.

If it's not an external wiring issue, then the fault is with the green channel inside the display. It is the electronic components on the green channel that have false soldering or poor contact. This situation requires repairs.

Second, connect the monitor to another host computer for use, if the fault disappears, it may be a fault of the graphics card. If the fault persists, it may be a fault of the monitor itself or a fault of the cable interface of the monitor. Focus on checking whether the metal pins on the interface of the monitor cable are broken or bent, if not, simply replace the monitor with a new cable and try again.

The solution to the redness on one side of the attached monitor:

Mouse click on the desktop right-click, Properties.

Turn on the Show Attributes box and select the "Appearance" option "Advanced".

Open the high-level appearance dialog box, and select "Color" > "Other Color" on the side of "Project".

Open the color dialog and change the hue and saturation and brightness to 85, 90, and 205, respectively. After setting, press "Add to custom color", and then press "OK".

After pressing OK again, the color dialog box will close, and then you can press OK all the way to the previous items. Until finally the system appears a "please wait" notification rollover box, wait for a while and set it.

6.What should I do if the monitor screen color is reddish?

When the corners of the display turn green or red, it means that there are some problems or faults in the display and need to be repaired in time.

1.Adjust the color settings of your monitor.

Adjust the color settings of the monitor in the preferences, and you can adjust parameters such as saturation and brightness to bring the color back to normal. You can also recalibrate the colors and adjust the color style of the screen to better suit your eyes.

If adjusting the color settings doesn't work, consider replacing the **cable**. Because the cable will wear out and age after long-term use, resulting in poor signal transmission, and even problems such as color distortion and image distortion, it is necessary to replace the new cable.

3.Replace the monitor.

If neither of the above methods can improve the greenish and red corners of the monitor, you will need to replace the monitor. Because this kind of problem can be caused by the failure of the monitor itself, replacing it with a new one can completely solve the problem of color distortion.

4.Check the graphics card.

If you have a problem with the corners of your monitor turning green or red, it can sometimes be due to a problem with your graphics card. To check if the graphics card drivers are the worst, you can also try adjusting the advanced settings of your graphics card, or restart your computer to fix the problem.

In general, when there is a problem with the display, timely treatment can avoid more serious problems in the future, it is recommended that you usually pay attention to the use of the monitor, computer or other electronic equipment, so as to check and maintain frequently, prolong the service life of electronic equipment, and add convenience to your work and life.
