What is the reason why Konka LEDR43 6000U TV screen has four horizontal lines that will flash?

1.It may be that there is a problem with the TV signal source or program source, mainly check whether the connection line is loose, or there is a problem with the current ** program source, which causes the screen to splash; If the cable is loose, it can be fixed, or it can be reconnected with a different cable; If it is a problem with the program source, you can switch to another program channel**.

2.If it is determined that it is not a signal source or a program source, it may be caused by the failure of the TV hardware, mainly due to the failure of the screen cable or poor contact, the failure of the display screen, the failure of the internal circuit, etc., which needs to be repaired by contacting the after-sales service of the TV to solve it.

If the TV screen has 4 horizontal lines and will flash, then it may be that there is a problem with the screen or a problem with the internal structure, at this time, you can only contact the manufacturer, or after-sales personnel.

What should I do if Konka TV flashes? How to solve it?

In general, there are three situations of Konka TV splash screen:

1.There is a problem with the source input of the TV that causes the screen to flicker.

In this case, you can check the TV and cable TV, set-top box or *** machine and other devices to see if their connection is loose, and reconnect it correctly and fix it.

2.There are other sources of signal interference around the TV that cause the screen to flicker.

Common sources of interference, such as high-power induction cookers, electric fans, refrigerators, etc., can be moved away from the TV.

3.There is a problem with the hardware of the TV that causes the screen to flicker.

TV hardware problems include screen failure, cable failure, internal circuit failure, motherboard and its parts failure, etc., at this time, it is recommended to contact Konka TV after-sales, please ask professional TV maintenance personnel for testing and repair.

1.Konka's HDMI-to-SoC path design or material reasons lead to problems with HDMI decoding transmission for a long time;

2.The HDMI path of the Tmall box and the motherboard does not match.

This is generally a major small probability problem, it is recommended to change the machine if you can change the machine, if you can't change the machine, try another box.

One is the sweepback line of the TV, which is caused by excessive acceleration voltage; The first is clutter, which is the shielding or poor contact interference image caused by the broken line. The sound performance is loud and loud, with no horizontal lines.

This TV screen has a total of four routes, and this one will flicker.

This estimate is a problem with your screen, and it is recommended to contact Konka's after-sales service personnel to deal with it.

This situation indicates that the TV screen is broken. Vertical lines or vertical bars appear on the LCD TV screen, which is a very common fault of LCD TV, which is basically caused by poor contact of the side plate, which may be loose, aging or other reasons, and can be operated as follows:

1. If it is a slight poor contact, you can pat the top or it may be restored;

2. If it doesn't get better, you have to contact the manufacturer's after-sales service, some brands of screens can be repaired by pressing the side plate to ensure good contact, but some brands can't be repaired;

3. If it has been insured, and the low cost cannot be repaired, it is recommended to scrap it, the cost of the screen basically accounts for 60-80% of the whole machine, and you can basically buy a new machine with low configuration of the same size for screen replacement.

Note:The screen belongs to the core component of the TV,According to the three-guarantee method, it is guaranteed for three years。

Konka led32R5500pdfThe left side of the TV shows red, green and blue vertical bars, which circuit board is wrong?

Dear,Hello very Zhichong is happy to answer for you:Konka led32R5500PDF TV shows red, green and blue vertical bars on the left side,Which circuit board is wrong? A:

It is estimated that the motherboard display chip is broken, and there is no other problem. If you want to fix it, it's usually 100-300, depending on the situation. By the way, it is recommended to change the data cable of the display first, sometimes the data cable will be broken.

There are usually two reasons for the vertical line of the LCD: 1. The cable problem of the motherboard circuit or the cable connected to the LCD screen, which is relatively simple to solve, can be solved by replacing the motherboard or cable; Second, the problem of the LCD screen, the LCD screen can only be replaced. National Three Guarantees Regulations:

The color TV machine warranty is a year, and the LCD screen is free for three years, and it takes you half a year to buy the bureau Zen, which can be repaired for free. I hope mine can help you, I wish you a happy life, if mine is helpful to you please give me a 5 star praise Oh, thank you for your support to me.

First make sure to flash a few times, halfway to wait for no, if you don't know, I can only tell you, power filter electrolysis, there is a problem, that is, the output section can generally be seen, not sure of all the change, not a few, not to check the light circuit, if it still doesn't work, there may be a software problem, you have to write the software according to your question, maybe you can't do it on the software, you have to pick up the board, now cheap about 100 yuan.

The power cord is in poor contact and loose.

Hello, the reason for the streak of the finger key on the LCD TV screen and how to deal with it:

1. Inside the TFT panel, connection problems and static electricity at the signal input end. Generally speaking, the cause can be preliminarily determined by visually observing the defect. The wires formed by static electricity are usually single and do not look that thick. Thick wires, on the other hand, are usually caused by short circuits.

2. The input terminal of the TFT internal short-circuit signal is short-circuited. The use environment is too humid, which will have a certain impact on the line of the Weiqiao input terminal and produce line defects. But it's not the only cause.

In this case, after ruling out the reason for your own use, you should contact the manufacturer to solve the problem.

Third, the strip is a cross line: it is relatively rare, caused by a short circuit or static electricity inside the TFT.
