What s the reason why my display has turned purple. Is it because the temperature of the display is

When I turn on the machine shortly after shutting down the system, the screen is purple and the icons displayed are blurry, etc. After a while, the color returned to normal again. What am I going to do?

Should I buy a new one? A: When there is an overall color deviation in the display, most of it is caused by a malfunction of one of the three color signals.

Your monitor seems to be missing a green signal and only a red and blue signal is left, which makes the screen appear purple. Since it returns to normal shortly after, it may be related to the system temperature and is likely to be a mechanical fault rather than a circuit issue. Because if the connection interface of the machine is not in good contact, when the temperature rises, the metal contacts will expand and the connection will return to normal.

If you still have the problem, you can connect the monitor to another machine or connect another monitor to the host, the purpose of this is to determine whether the problem is on the monitor or the graphics card. If the problem is with the monitor, then you may have to spend hundreds of dollars to fix it. And if the graphics card is faulty, generally speaking, it is not worth repairing, and you should buy a new one to replace it.

If it is an LCD screen, the lamp may be aging, and the lamp can be replaced, about 100 yuan. If it's a picture tube, go fix it.

It's the terminal of your monitor** or the crimping is bad, and there is no way to fix this.

1. The screen is broken, and the LCD panel is broken, and it costs a lot of money to replace the entire screen assembly.

2. The cable is broken, which is caused by the burning or falling of the cable connecting the screen and the motherboard. It would be nice to change the cable like this.

3. The motherboard is broken, and the entire motherboard needs to be replaced, but this probability is very low, but it is not ruled out. The way is to replace the motherboard, which is generally a little cheaper than the screen. After the mobile phone is subjected to strong vibration and compression, it may become false welding, short circuit, partial damage to the screen, false connection of the cable base, deformation of the mobile phone case, etc.

Solution. 1. The purple screen of the mobile phone is a kind of flower screen. The causes and workarounds for the screen are as follows:

The cable is broken, the cable connecting the screen to the motherboard is burned or detached, just replace the cable. The screen is broken, the LCD screen is broken. Can't do that.

This is the most troublesome. Replacing the entire screen assembly is very expensive.

If the motherboard is broken, the entire motherboard will also be replaced, which is very low, but it cannot be ruled out. The way to do this is to replace the motherboard. Motherboards are usually cheaper than screens.

Please press the switch button, turn off the phone, restart, and see if it works. If not, there may be leakage on the screen, and you need to send the phone to the after-sales service for processing.

2. The purple screen of the mobile phone is a kind of flower screen. This is a leakage from the phone's screen display, usually caused by the phone falling off the screen. The so-called screen leakage is to become liquid crystal.

If it is pressed strongly by external force, the internal part of the LCD panel will be damaged, and the liquid crystal will gradually leak. This was invisible at the time, and after a while, a noticeable lump appeared on the screen. In the past two years, with the gradual improvement of the quality of mobile phone screen glass, this situation has been greatly alleviated.

However, it is easy to appear on some low-end models now.

There are generally only two reasons why a computer display turns purple:

The VGA cable of the computer is damaged, resulting in a poor connection to the monitor.

The connection port of the monitor is not in good contact with the VGA cable, resulting in the loss of color.

The solution is also very simple:

Replace a good VGA cable and connect it again.

Plug in the monitor connector and VGA cable firmly and tighten the screw.

The color of the screen turns purple, it may be due to improper color matching, the data cable connection is loose, the graphics card is damaged, and there is a problem with the screen. 1. First of all, check whether the color setting is normal, there is a menu key "menu" on the screen to open the screen setting. 2. Select the "Color" item, then select red, green, blue, press the SET key, all settings are in a balanced state, generally check whether the data cable connection of the monitor is loose, unplug and plug it back in.

2. If the data cable is damaged, please replace it.

If the test steps are as follows:1First check if the color settings are normal, there is a "Menu" button on the screen to open the screen settings, then the screen color changes to purple, which may be due to incorrect color settings, loose data connection cables, damaged graphics cards, and display defects.

2.Select Color, and then select red, green, and blue, respectively. Press the adjust button to adjust it to the balanced state, usually left and right.

Check that the monitor data connection cable is not loose, unplug and reconnect. 2.If the data cable is damaged, replace it.

There are times when our computer monitors are purple, what's going on? So let me tell you about the reasons for the purple color of computer monitors and how to solve them, I hope it can help you!

Solution 1 for the purple color of the computer monitor:

The reason for this is usually due to magnetic field interference or poor contact with the graphics card.

1.Determine whether the bending is magnetic field interference: the main symptoms of the display being magnetized are that there are some areas where Wang Li appears "color spots", and the local image is darkened or the color becomes lighter and buried.

Solution: The current display, more have the degaussing function, after entering the settings menu of the display, select the degaussing menu, the display screen shakes, and the degaussing process is completed (it may need to be repeated several times). If it still doesn't work, the reason is poor contact with the graphics card.

2.Solution to poor contact of the graphics card: check each connector at boot, plug and unplug it repeatedly, and then power on and check it when the back cover is opened, and repeatedly check the connector and signal cable until the fault is eliminated.

Secondly: 1. It may be that the display is aging or there is a hardware failure.

2. There may be a problem with the computer's graphics card (if it is connected to the graphics card).

3. It is recommended to change the host and connect it to your monitor to see if the same problem occurs, if it is, it is a problem with the monitor, if it is not a problem with your original host, you can fix it.

Solution 2 for the purple color of the computer monitor:

Open the control panel and find "Appearance & Personality";

Go to "Adjust Screen Resolution";

Once you're in, select "Advanced Settings";

Locate the Color Management tab;

Go to Color Management and turn on Advanced Options;

Open the calibration display at the bottom of the menu;

1. The connection port between the monitor and the chassis is not in good contact, which will cause the color to be missing and the computer display screen will turn purple;

2. The sudden abnormality of the circuit of the cathode ray picture tube to process the primary color will cause the computer display screen to turn purple;

3. Wet short circuit or aging of the display will also cause this phenomenon;

4. There is a problem with the chromaticity control circuit or chip of the graphics card;

5. A broken color manager in the monitor will also cause the computer display to turn purple;

6. The magnetic field around the hidden guess chain of the display will affect the display screen of the computer, resulting in color disorder;

7. This situation will also occur when the signal mega cable is in poor contact with the graphics card or display, or there is a broken circuit inside the cable and a poor connection to the stove.
