The display shows one less color, and the display color is not vivid enough

1.Check whether the monitor data cable connector has broken needles (as an example in the figure below)2Check if the cable is connected to each other and shake it with your hand.

3.If none of the above works, then you can only repair it for about 30 yuan.

When the display shows one less color, it is mainly caused by the problem of the decoding circuit in the display, or the leakage of some small capacitors causes the output power of the cathode tube of the three primary colors to be insufficient, resulting in the failure of one of the three color signals. The display is left with only a red and blue signal due to the lack of a green signal, which makes the screen appear purple. Since it will not take long to recover, it is estimated that the display decoding circuit is not likely to be damaged, and it may be related to the system temperature, if the graphics card is not in good contact with the display interface, when the temperature rises, the metal contacts will expand to restore the connection to normal.

Solution: Connect the monitor to another host computer, if the fault goes away, 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 monitor cable interface.

Focus on checking whether the metal pins of the monitor cable interface are broken or bent, if not, simply replace the monitor with a new cable and try again.

There may be 3 aspects to judge:

1.Graphics card issues.

Replug it in, clean the gold finger, and see if the fan is normal.

If it doesn't work again, it will be replaced free of charge during the warranty period).

2.Cable problem (replugging, checking VGA or DVI interface) 3Display issues (Check if the electrical outlet is powered on.) If it's convenient, connect it to other computers to see if it's normal).

It's not possible to restore with one click. If you don't have a system disc ready, the optical drive can be used. Start the computer and press the DEL key, set it to a disc boot in the BIOS, insert the system disk and reboot, basically complete it automatically according to the steps.

I fainted you, that's a problem with the degaussing resistor, it should be the capacitor on it bursting. Just change it. It's not anything damp.

The CRT display is aging, the coil inside is burned out, it is not easy to repair, and it is meaningless to repair and should be eliminated. It is recommended to buy a cheap LCD, which is not expensive for about 600 yuan.

First, the green line inside the signal line is broken.

Second, there are elements with poor contact in the tail plate of the picture tube.

There are generally two possibilities.

1VGA wire poor contact.

2 is that the display tube of the display is broken.

Operating Equipment: Display.

Here's how to set up the display if the color is not bright enough:

1. Open the control panel. In the Control Panel, select Appearance & Personalization. (as shown in the image below).

2. Enter the appearance and personalization interface and select the display button. (as shown in the image below).

3. After entering the display interface, click the calibration color button. (as shown in the image below).

4. Next, an interface showing color calibration appears, and then keep clicking "Next" until "Adjust Gamma" appears, and slide to the lowest value. (as shown in the image below).

5. Continue to the next step until it is completed, a new window pops up, close it directly, and you're done. (as shown in the image below).

Advantages and disadvantages of liquid crystal display and principle:

Thin, does not take up space; No radiation, good for health; No flickering, good for the eyes; Low energy consumption, much smaller than CRT displays, saving energy; Completely flat, no visual distortion.

There is a viewing angle, and the viewing range is smaller than that of CRT; There is a response speed, which will cause screen dragging.

When an electric field is generated by the electrodes in the LCD, the liquid crystal molecules are distorted, so that the light rays passing through it are regularly refracted and then displayed on the screen through a second filter layer. <>

The color of the display screen is incorrect, you can adjust it according to the following steps (take Win7 N card as an example):

Click "Start Control Panel" to open the Control Panel;

Click on "Hardware & Sound";

Click "NVIDIA Control Panel" to open the NVIDIA Control Panel;

Click "Adjust Desktop Color Settings" in the left menu bar;

Click "Use NVIDIA Settings" on the right;

Click "Blue" in the "Color Channel";

Drag the button like "progress bar" below to adjust the blue channel moderately to make it a satisfactory color;

Adjust the "green, red" and other channels according to the step-by-step method to make its color satisfactory;

Click the "Apply" button to save and make the settings take effect.

When the hole row setup is complete, close the NVIDIA Control Panel and Control Panel.

Causes: Incorrect setting method, malfunction of the monitor VGA cable, or malfunction of the monitor itself.

Solution: 1. Open a web page, here take 360 browser as an example;

2. Look for the Tools tab at the top of the browser, and then select "Internet Options" from the drop-down list in this tab;

3. Then select the "General" tab in the window that opens "Internet Options";

4. Subsequently, click the "Accessibility" button, and then you can see the buried car to a pop-up dialog box;

5. Finally, uncheck the box in front of the "Ignore the color specified on the web page" tab.

6. The above method can not be solved, and a good display needs to be used to bend and replace, if the problem is not there after replacement, the display needs to be detected and repaired.
