Strange LCD screen bright lines, LCD monitors have bright lines

It's not a problem with the wiring, it's a big picture that is abnormal.

The cable inside the screen is not in good contact with the glass PCB or circuit board, resulting in the bright line coming and going.

This problem is a very serious quality problem for the LCD screen, and the screen must be changed, and it cannot be repaired by any method.

There is still some truth in saying that people who shoot ** with a camera.

The bright line on the LCD may be a problem with the panel or the module.

Teach you a simple way. Look at the bright line and take a picture first.

Then you see whether the bright line runs through both ends of the screen, if it runs through both ends of the screen, then the bright line is not the same brightness from beginning to end.

If the bright line is the last phenomenon, then the problem of this bright line appears on the module, and it can be solved by after-sales repair.

If it is half a bright line or through the bright line and the brightness is different, it is a problem with the LCD panel, and this kind of screen can be changed for you.

It is not recommended to shoot out the bright line, the force is less than half will not come out, and the force is large, and the parts inside are damaged, and you don't want to think about repairing them.

I would like to tell the Level 6 respondents one thing, the LCD of the TV computer is not connected to a decoder board, but a soft circuit board. Although I don't understand the decoder board you said, the process after making the glass panel of the LCD monitor is equipped with a module to install the backlight, which has nothing to do with the decoder board.

If it is during the warranty period, it is recommended that you break it quickly, you can shoot the top of the line, that is, the cable of the decoder board connection screen is loose, it is quite difficult to get, it must be repaired with professional maintenance tools, and it is quite difficult to get it right.

The screen thing, specifically the screen line, not the screen line behind the screen and the motherboard, is the screen line between the circuit board and the LCD screen behind the screen, there is a virtual connection, you need to use a screen presser to repair, there is no such equipment in the general place, the equipment is 100,000 yuan.

It is recommended that you take a camera shot when the malfunction occurs** as proof of the malfunction.

Then what do you ask, warranty (it may be that the MOS tube is soldered).

Connect the monitor to another console and if the fault goes away, it may be a malfunction of the graphics card. If the fault persists, it may be a fault of the monitor itself or a fault of the monitor cable interface. Focus on checking whether the metal pins of the monitor cable interface are broken or bent, if not, simply replace the monitor with a new cable and try again.

1. Problems with power or data cables.

2. There is a problem with the graphics card or graphics card driver (try another one or upgrade the graphics card driver).

3. Whether there is electromagnetic interference in the use environment.

4. The mains power is unstable, the display itself is faulty, and the electronic components inside the display are soldered.

If the bright line can't be removed, it's better to overhaul it.

There are many reasons for this, but you are not in this business, so I am afraid that you will not understand it if you are too professional, so simply pay attention to the following:

1.There should not be too much vibration to prevent internal friction;

2.Pay attention to dustproof, especially the screen, so that no dust can fall into it;

If you usually strictly follow the above 2 points,Congratulations,The bright line has nothing to do with your playing games,That's the problem of the screen itself (that is, there is a problem between the upper and lower 2 pieces of glass),If it is within the warranty period,You can directly replace the goods,The original factory is guaranteed for this phenomenon
