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.
