What is the reason why LCD TV screens have straight color stripes?

There are straight stripes, which is caused by the poor contact of the Pingmu cable, because the Pingmu is made of glass and the wire is welded together with two different materials, and this situation will occur after a long time, and the screen needs to be re-pressed! The cost is higher, about three or four hundred yuan.

Types of Line Defects:

Horizontal lines: usually white. There are three main categories of causes:

Inside the TFT panel, connection issues and static electricity at the signal input. 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.

The thick wire is usually caused by a short circuit, and the input of the TFT internal short circuit signal is short-circuited. If the use environment is too humid, it will have a certain impact on the line at the input end 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.

Vertical lines: Usually colored. The causes are similar to those of the horizontal line. A single circuit is an open circuit, and multiple circuits are short circuits.

Crossovers: Rare! TFT internal short circuit or static electricity. (It's more in line with the landlord's situation, or it may be that your collision induces this potential failure.) ）

The yellowish color of the LCD is caused by the failure of the polarizer or the yellowish backlight.

In short, it's all a TFT-LCD problem.

I guess the screen is broken! If it doesn't affect the viewing very much, it's best not to change it for the time being (unless the long party agrees to be free or subsidized). Wait for the ** will be lower in the future and then consider it.

Summary. Possible reasons for color streaks on LCD TVs:

1. The backlight plate of the TV is abnormal or broken.

2. The picture tube of the TV is broken and needs to be replaced.

3、The phenomenon of virtual welding of TV circuit should first find out the position of virtual welding of the circuit,After finding the position of virtual welding of TV,Re-weld the place of virtual welding,Connect it well to solve the problem of TV screen blurred screen caused by virtual welding of TV circuit board。

I wiped it with alcohol and that's it, what's the reason?

Are you pressing too hard?

No, I don't. No, I don't.

Then you can open it again after a while, and it will be like this, even if the backlight plate is broken.

How much does it cost to replace the backlight panel, 65-inch curved screen.

How much does it cost to replace the backlight panel, 65-inch curved screen.

Just check it is normal to watch, and after half an hour, the screen suddenly goes black, and after half a day, it becomes like this, and it looks like this after half a day, and it looks like this after half an hour.

Thanks, can you be sure that the display is not broken?

Thanks, can you be sure that the display is not broken?

The display is not broken.

I feel that the short circuit of the components caused by the flow of alcohol to the bottom of the screen when spraying alcohol, is it possible? Thank you, I feel that the short circuit of the components caused by the flow of alcohol to the screen when spraying alcohol, is it possible? Thank you There is still a high possibility of too much alcohol.

Generally, it is caused by the abnormal power supply voltage of the logic board line, and the unstable power supply voltage will affect the reception of the TV signal, which will also lead to this situation. Secondly, it may also be caused by static electricity, and it is necessary to eliminate the interference sources that cause static electricity, and if you have no way to solve it, you can find professional maintenance personnel to repair it. There are several ways to avoid the above problems:

1、First of all, when you find that the screen has color vertical stripes, you should first check whether other electrical appliances around you have interference sources that interfere with TV signal reception,Secondly, we should also pay attention to the maintenance of TV when we use LCD TV in daily life,Don't use it for too long,Or stay in the same picture for a long time。 2. Because the screen of the LCD TV is very fragile, it should also be protected in daily life to avoid violent impacts, especially if there are children at home, it is necessary to pay attention to the damage to the screen in the process of running and playing. 3. Check whether the line of the TV is loose, if the line is loose, it may also lead to the appearance of color vertical stripes on the TV screen, so it should be checked or replaced in time.

4、The screen of the LCD TV should also be cleaned from time to time,Avoid dust blocking the line and causing a short circuit,When wiping the screen, you can choose to use a soft cotton cloth to wring out the water as much as possible and wipe it gently,If you use a rough towel, it is possible to scratch the screen and affect the perception,And the TV should be placed in a dry environment,Water vapor in a humid environment is very harmful to the TV。

Double-check the TV's link line. No, change the wire. It's not a TV problem, and you need to go to a repair shop to see it.

Factory-line output problems may be that component burned or loose.

There is a wire in the monitor or the original foot is loose

Have you fixed it? How much? That's how my house is broken.

The temperature of the LCD is too high and the contact of the display tube is not smooth. This can also happen if the temperature is too high and the signal is not transmitted smoothly, forming horizontal lines, and the wires are disconnected or in poor contact.

First of all, it may be that there is a problem with the signal source or program source of the TV, which causes a lot of horizontal stripes to appear; It is also possible that the screen cable is faulty or the contact contact is poor, the display screen is faulty, the internal display circuit is faulty, or other parts are faulty.

It could be that the TV signal is not good, or that it is interfered with, or of course it is because of a problem with the screen.

It is possible that the output tube is soldered, which causes a problem in the field scan circuit section, or it may be that the signal input is short-circuited. Because the environment is too humid, it will have a certain impact on the line at the input end and cause line defects.

Hisense TV,What's going on with horizontal stripes? Is it broken? Distress.
