The reason of the notebook computer screen color

Two graphics BGA package chips Weld damage overheating, welding equipment and technology through professional BGA package, reset or change the video card, two screen lines on the screen on the mobile screen flowers, flower screen, change you change the screen to solve it is to repair the line.
Similar phenomenon explained:

Basically caused by the above reasons, the laptop screen is to spend this case, of course, there are some cases, after the judge's recommendation or simple, after-sales service, and see it. Under normal circumstances, as long as the notebook, maintenance-free, 08 notebook is still the case agree now.
Another lead to spent laptop screen reasons:
A driver's problem,
The notebook computer as a drive is no problem with the graphics chip companies write, chip manufacturers to provide notebook computer manufacturers of chips, drives to write, so there may be some compatibility issues. Laptop drive level is very slow release time, usually six months or a year. When we can solve the first attempt to look at running other 3D program is there to spend the screen, the phenomenon, if the problem goes away, we can consider the compatibility issues. The same time, the driver file is damaged or lost, may cause the phenomenon of the graphics crash, spent the screen, you wait to resolve this issue simply uninstall the old drivers, install the driver can.
Second, third-party software
Overclocking and open software, the memory frequency is more than a head, the image map error, take the phenomenon of the screen just fine, so serious that it led to crashes. Because the operating frequency of abnormalities in the video memory, a higher frequency, not only to become unstable, especially in the read and write data can easily make mistakes. At this point, we only need to reduce or reply to the default frequency can be.
Of course, the above claim, we spent the most basic method of the laptop screen failure, the fault remains after debugging we should turn from the hardware side. My personal experience, the phenomenon of laptop screens are generally hardware problems, software problems in a better compatibility.
Third, the LCD panel production line is poor contact
This is the first step we check the hardware. Screen, you are not a normal phenomenon, or pat on the surface of the keyboard failure after the disappearance, which are often poor because the signal effect caused by exposure to the LCD interface. We just need to bear in the corresponding interface problems can be removed.
Fourth, the oxidation reaction
In general, this notebook computer in harsh environments, or after prolonged use and easy results, treatment, we will first LCD line interface, its joint eraser Goldfinger, for small interface is not water and alcohol to clean the amount of cotton, the aim is to remove dirt and oxidation of agricultural products, or due to poor contact phenomenon. After treatment, and again the line is connected, check whether or not to tight.
Five, Memory
Dynamic Video Memory Memory Technology (DVMT is, dynamic video memory technology) As part of the notebook computer graphics, part of the memory capacity allocated for the video card memory. In actual operation, may be due to memory internal structural damage caused by this part as a memory, the data exchange in the video memory chips are often a problem, screen, and you spend, or even the collapse of the phenomenon. In this case, we can use the substitution method, the replacement of the same specifications of the memory check. Of course, if the memory is integrated on the laptop motherboard, we can only carry out maintenance.
Six, the ability to problem
RAMDAC (random access memory digital - analog converter) and the filter capacitor are two important factors determining quality of the position or the fall of the video card. The quality of the work of the filter circuit and the capacitor quality is of mutual value, use of poor quality capacitors or capacitor itself characteristics decline to spend the screen, you seem accustomed to the strange phenomenon. Solution, we can use a multimeter to check capacitor problem, then replace with the same specifications, this problem will be solved.
