LCD TV is used as a display screen, but the fluorescence in the color is too bright, how to adjust

Pro,The method of adjusting the blur of the fluorescent screen of the color TV is as follows,First、After the TV is reset and the TV is turned on,Use the remote control balance to adjust the TV clarity to0。 Because if the sharpness is turned up too high, the sharpener of the edge of the TV will be higher, and even stray spots will appear, and then adjust the "image" of the TV to the lowest. 2. The base of the picture tube is damp and humid in the rainy season and southerly weather, due to the relatively large air humidity, the base of the picture tube is damp.

Don't worry,After the TV runs for a while, the temperature will rise,The damp vapor will evaporate,The voltage has risen,At this time, the blurred situation of the TV has improved significantly,At the same time, the picture becomes clearer。 Third, the aging of the header of the picture tube will cause the voltage drop of the picture tube, resulting in the TV picture becoming blurred, the aging of the picture tube socket, it is recommended to ask professional maintenance personnel to come to repair, ** will not be very expensive, it is enough to replace the picture tube base about dozens of yuan. If you have a strong do-it-yourself ability, you can also replace it yourself.

Summary. Hello, glad for your question, 1. Adjust the brightness and contrast of the TV, and adjust the brightness and contrast to the appropriate position. 2. Replace the fluorescent tube lamp of the TV and replace it with a new fluorescent tube lamp, which can effectively improve the blurred picture.

3. To clean the phosphor screen of the TV, you can use a soft cloth to take a neutral detergent to clean the surface of the phosphor screen by gently wiping it, and avoid wiping the phosphor screen with a knife or sharp object, so as not to damage the phosphor screen. 4. Check the power cord of the TV, check whether the power cord of the TV is damaged or loose, and if so, it needs to be replaced in time.

You've done a great job! Can you elaborate on that?

You roll the silver well,The blurred screen of the color TV is caused by the improper setting of the TV or the problem of the TV hardware,You can take the following operations to adjust:1、Correct the TV setting:Change the TV setting to "automatic",Then adjust it according to the specific instructions in the TV operation manual,Adjust the brightness、Contrast、Color and other parameters of the TV,To achieve the ideal display effect。

2. Clean the phosphor screen: Use a soft cotton cloth to gently wipe the phosphor screen, if there is oil stain, you can drop a few drops of water on the cotton cloth to avoid scratching the fluorescent screen. 3. Replace the hardware

If the above exercises are ineffective, it may be that there is a problem with the hardware of the TV, and you can consider replacing the relevant hardware or finding a professional to repair it. Thank you for your question, I hope it will be of some help to you.

Summary. 1. Check whether the screen adjustment switch of the color TV is in the "extreme" state, and if so, change it to the "standard" state; 2. Use the remote control to adjust the brightness and chromaticity of the TV, adjust the brightness to be smaller, and the chromaticity is larger, so that the picture color is fuller; 3. Check the signal source of the TV, if it is a signal from an external device, adjust the output quality of the external device to make the signal clearer; 4. Check whether the screen of the TV is dirty, if so, you can use a cotton swab dipped in some warm water to clean the screen; 5. Check whether the receiver of the TV is sensitive, if not, you can try to replace it with a higher quality receiver.

Fellow, I really didn't understand, I can be more specific.

1. The contrast of the TV is set incorrectly, resulting in blurring. 2. First of all, you can enter the menu of the TV. 3. Then find the image settings, and then select the contrast setting.

4. Then press the volume + - button to increase or decrease the contrast, and then repent. 5. There is a problem with the signal source input or program source of the TV, which causes the picture to be blurred. 6. Lu Zheng, if it is a problem with the source of the program, you can change it to other program channels.

without affecting other fluorescent spots. These signals are received by a color television set and control three electron beams in a color picture tube.

There are 400,000 small holes on the board, other than blue.

The colors are produced by additive color mixing to be sure.

Make sure that each electron beam falls on only one set of fluorescent spots. To put it simply, a color TV phosphor screen.

The color image on is produced in this way, each group has three fluorescent spots, blue light, after the lens of the TV camera ingests the image, each electron beam produces one of the three primary colors of color light on the phosphor screen, each small hole corresponds to a group of fluorescent points, by the three camera tubes respectively to feel the red in the light, separated by a blind, green, utilized.

The refractoscope divides the light into 3 channels, and the color image that appears on the phosphor screen of the television is composed according to the principle of additive color. in electronics.

Between the beam and the phosphor screen, green and green, they are excited by the electron beam to produce the corresponding red. The three primary colors of light, red and blue, will then be felt.

The light is converted into an electrical signal. The CRT contains 400,000 sets of fluorescent dots on the outward side.
