The lower half of Haier s LCD TV occasionally flickers

Hello, thank you for asking the company.

First of all, it is necessary to rule out the problem that is **.

The common reason for the splash screen may be a bad signal, a broken screen, or a damaged movement.

First, you can broadcast the normal cable TV signal first, change a few stations to see, whether there is a screen flashing phenomenon, is it the same position, if after changing the channel, the screen is no longer flashing, that is the signal problem. If there are any, proceed to the second step;

Second, insert a USB flash drive or mobile hard disk with a film source, and if there is no screen flash, it means that there is a problem with the wired signal. If there is a screen flicker, it may be a problem with the screen or the movement;

Of course, it may also be that the connection line between the screen and the movement is loose or poorly plugged.

If it is the reason for the screen, then the screen needs to be replaced, which is more troublesome and will take a long time.

You can feed back the details to Haier's official BBS,Enter the color TV community,Or you can also post it to the post bar Haier bar,There will be Haier color TV technicians to answer for you。

You are welcome to ask the company questions again.

We wish you a happy work life

This should be a problem with the LCD driver board. The aging of the field sensing tube is unstable, or it receives electromagnetic interference locally, resulting in interference in the voltage value of some circuits.

If there is a warranty, it will be sent directly to the after-sales service, and if there is no warranty, it will be sent to the repair appliance to check the driver board.

Hello The reasons for the splash screen of Haier TV are as follows:1、There is a problem with the signal source input of the poor dust TV, which causes the flickering screen of the wide guide shed。 Generally, you can check whether the connection between the TV and cable TV, set-top box or virtual Zen *** machine is loose.

2. There are other signal interference sources around the TV that cause the screen to flicker, such as high-power induction cookers, electric fans, and refrigerators. 3. There is a problem with the hardware of the TV that causes the screen to splash, including screen failure, cable failure, internal circuit failure, motherboard and its parts failure.

It is also very likely that the antenna has poor contact, resulting in abnormal signal supply bridges. 3. If the TV is subject to slight electromagnetic interference during use.

It is also very likely to cause the TV screen to flicker non-stop. Suggested solutions:1、In the process of use,This situation suddenly occurs,Check whether the power supply is abnormal,If there is an abnormal space or voltage instability,You need to adjust the power supply,Or install a power regulator,After the voltage is stable,Only such a situation can be avoided。

2. If it is found that it is caused by a fault in the signal source, it is necessary to check the antenna or the input line, and repair the signal source after finding the specific reason, which can also solve the problem of the screen flickering. 3. If you find that there is slight electromagnetic interference around, if you are in this state for a long time, you need to change the position of the TV to be able to solve it completely.

2. If it still can't be turned on, it means that it is caused by the hardware failure of the TV. 3. If it is determined that the hardware failure of the TV cannot be turned on, it is recommended to contact the after-sales service of the TV to conduct a comprehensive inspection and maintenance of the TV. Television (TV) refers to a device that uses electronic technology to transmit the image picture and audio signal of the event, that is, a television receiver.

It is also an important broadcasting and communication tool. Television was first invented in 1925 by British engineer John Logie Baird. Television uses electricity to transmit visual images of the event in real time.

Similar to movies, TV uses the visual residual effect of the human eye to show a still image with a gradual change of frames, forming a visual living image. The transmitter of the TV system converts the various fine parts of the scene into electrical signals according to brightness and chromaticity, and transmits them sequentially. At the receiving end, the luminance and chromaticity of each tiny orange hole are displayed according to the corresponding geometric position to reproduce the entire original image.

The progress of science and technology is an important reason for the rapid popularization of television. The scanning system of television signals in various countries is not exactly the same as that of channel broadband, and is distinguished by Latin letters according to the recommendations of the International Radio Advisory Committee (CCIR).
