What should I do if the background color of the TV is green?

If it is the overall color cast, the reason is that there is a problem with the trichromatic channel, and it has nothing to do with magnetization or not. If the local color is biased,Color TVs have degaussing circuits,Generally, it starts automatically when it is turned on,Repeated switching several times can solve the problem,If not,It is caused by the geomagnetic effect,You may be able to solve the problem by changing the direction of the TV,If it doesn't work,Then you have to use a degausser,Generally, electronic components are sold in stores,It's not too expensive。

If the warranty period has passed, now teach you how to adjust the overall color cast:

Open the back cover, and there is usually a circuit board on the back seat of the CRT, on which five potentiometers can be easily found. The normal situation should be like this, it is two color drives, three color base level adjustments, generally English signs, not too difficult to understand.

You set the brightness of the TV to be darker, the color is completely turned off to black and white, adjust the base level of the two colors, it's very simple, if there is more red, reduce red, if there is more green, reduce green, and if there is more blue, it will be the same. Anyway, it's white.

Then set the TV brightness to the brightest,Adjust two color drivers,The modulation method is the same,It's just that it may lack a color,At this time, you can increase or decrease the two colors you can adjust at the same time。 After the adjustment, return the color and brightness settings to normal, and the color of the TV will be pure.

This method is very useful for the color shift of the old TV,It's not too difficult,Business people will do it after reading this article I wrote,Just pay attention to the display tube high-voltage cap on the high-voltage cap20000V high voltage,There is a high voltage on the focal voltage line of the picture tube base,Be careful not to approach。 Anyway,The voltage in the color TV is relatively high,You just pay attention to it。

Okay, that's it, you try it, it's not very difficult.

But I also want to tell you a little bit, if your fault is not a color cast, but a lack of color, this point should be very serious in your opinion, so that you can't find a certain color at all, this is not a color cast failure, but a channel in the three channels is damaged, to judge separately, this is a bit difficult, it is not easy to introduce here.

Measure the negative collection voltage of the video amplifier circuit 3.

Whether it is normal or not.

Check the circuit first, see the pole, and whether the tail circuit is normal!

Then check the chromaticity decoding circuit (that is, the manifold).

If there is no abnormality in the circuit, there should be a problem with the CRT electron gun!

There are three main reasons why a TV screen turns green

One: The TV is magnetized, if you find that a certain part of the TV knowledge appears green, then you may wish to try to remove the TV and degauss it. See if the green patch is still there.

Usually there will be something with magnets next to the TV, just remove these things.

2: The problem of the green gun, the green vision tube B-E pole open circuit, green gun yin, grid touch pole short circuit, green gun voltage is too high and other may make the TV screen green.

Three: The problem of the phenomenon tube, the red and blue filament of the picture tube is broken, two guns, and the picture tube is used for too long, aging, and the phosphor layer is burned out, which will cause the problem of the TV turning green.

How to solve the problem of TV turning green?

We can know the approximate maintenance content after we have a general understanding of why the TV turns green. Generally speaking, if it is a magnetization problem, as long as it is demagnetized, it can be degaussed, and the degaussing function that is usually inherent in the TV can be demagnetized; You can also turn it off, wait for 15 minutes before turning it on, and then turn it off, so repeat it about 3 times to basically demagnetize. Of course, the premise is to take away the items that affect the magnetization of the TV set, especially the speakers, magnetized cups, etc.

If it's for other reasons,It's best to find a qualified maintenance master to carry out maintenance,Mainly check the video release plate、Picture tube、Color decoding circuit、Electronic gun filament power supply and other problems to find the reason why the TV turns green。 Generally, the maintenance cost of these TV failures is very cheap,According to the size of the TV or the different parts**Slightly different,Generally, there are these three grades。

If the color of the LCD TV turns green, it is most likely because the proportion of green displayed on the LCD TV screen is too high. This situation may cause the display color of the TV to deviate from the true color, which can affect the ** experience. Here are a few workarounds:

1.Adjust the color tone: LCD TVs are usually equipped with a number of color adjustment options through which the color can be adjusted. Look for the "Tint" or "Display" option in the TV menu and adjust the green ratio until the colors return to normal.

2.Confirm the source: If you're using an external device (such as a *****), the output port of that device may also affect the color of your TV. Power off the device and restart it, or try replacing the cable and see if the issue is resolved.

3.Perform a reset: Sometimes, there may be some unknown issues with your TV, and performing a reset may clear the problem. Look for the "Settings" or "System" option in the TV menu, find the "Reset" option and confirm the execution.

4.Check the light source: If you're not sure what the source of the problem is, you can try to determine if there's a problem with the light source.

If your TV is in an environment that is too bright or the lighting is uneven, you can cause color deviations, so try adjusting the ambient light or moving the lights near the TV to see if you see better.

After trying these methods, if the problem persists, you can contact your TV manufacturer or after-sales service center for more specific technical support.

If the color of your LCD TV is greenish, you can try the following solutions:

1.Adjust the color settings: In the menu or settings options of your TV, find the color or image settings, try adjusting parameters such as color balance, hue, saturation, etc., to adjust the green color to the appropriate position.

3.Check the cables: Check the cables between your TV and the TV signal source (e.g., set-top boxes, *****, etc.) to make sure that the cables are not loose or damaged, which may cause color problems.

4.Reset TV: Try to restore your TV to factory settings, which can be done through the reset option in the TV menu. Please note that this will delete all user-defined settings, so back up important data.

If none of these methods work, it is recommended that you contact your TV's after-sales service or professional repairers for overhaul and repair. They can provide more accurate recommendations and solutions on a case-by-case basis.

There are three main reasons why the TV screen turns green:

1. The TV is magnetized, if you find that a certain part of the TV knowledge appears green, then you can remove the TV and carry out degaussing work to see if the green color block still exists.

2. The problem of the green gun, the green view of the open circuit between the B-E poles, the green gun yin, the gate touch pole short circuit, and the high voltage of the green gun may make the TV screen green;

3、The problem of the phenomenon tube is trapped,The red and blue filament of the picture tube is broken、Two guns,As well as the picture tube is used for too long,Aging,Phosphor layer burns out, etc., will cause the problem of TV turning green。

First of all, there can be a number of reasons for the problem with the green color of the TV screen, which could be due to a signal problem, a line problem, or a problem with the TV itself. We can try to carry out the following repair methods: 1. Check the signal sourceFirst, if you are using a cable TV or a digital TV set-top box, you can first check whether the TV signal source is normal.

You can try switching to a different channel, if the image color of the other channel is normal, then the green screen may be due to a problem with the signal source. 2. Check the lineWhen the signal source is normal, you can check whether the line of the TV is connected normally. You can check the cable between the TV and the source for loose or poor contact.

If you find that there is a circuit problem, you can plug and unplug the circuit again, or replace it with a new one. 3. Adjust the image settingsIf the first two methods fail to solve the problem, you can try to adjust the image settings of your TV. You can go to your TV's settings menu, open the image adjustment options, and adjust parameters such as color saturation, brightness, and contrast to see if you can restore normal colors.

Fourth, contact professional maintenance personnelIf the above methods cannot solve the problem, then it is very likely that there is a problem with the TV itself, at this time, it is recommended to contact professional maintenance personnel for repair. In short, no matter what causes the TV screen to display green, we can solve the problem with the above methods. The best way to do this is to keep your TV clean and maintained, which can avoid many common failures.
