The cause of the laptop computer screen color

Two possible is a toshiba pa3128u-1bas battery video card BGA encapsulation chip overheating in virtual welding damage, through professional BGA encapsulation welding equipment and technology reset or change a video card good two is screen line is bad in the flower of screen move screen to see flowers screen have change you have change is screen problem solving it repaired line.

Basically cause laptop toshiba pa3128u-1brs battery screen above the reason is spent this situation, of course, also have the following some circumstance, the proposal or simple after judge, to after-sales and see it. Usually, as long as there was in the notebook is free of maintenance, 08 notebook agreed under the condition of the still in the now.

The other kind of lead to spend the cause of the laptop screen:
A driver problems,
As laptop computers toshiba pa3191u-1bas battery of the driver is not graphics chip company write, chip companies offer chip, drive of the problem is to the notebook computer manufacturers to write, so there may be some compatibility problems. At the same time laptop drive degree very slowly release time, generally for six months or a year YiGengXin. When we can solve first try to see run other 3 D whether the program also present flowers screen, you phenomenon, if the problem disappear can be considered compatibility problems. Meanwhile, the driver file is damaged or missing, may lead to video card occurs when the crash, running off flowers screen, you wait for a phenomenon, solve this problem just unload the original driver after, to install the driver can.

Second, third party software
Overclocking open software, if the video memory frequency more than a head, the picture map errors, take screen phenomenon just fine,toshiba pa3191u-1brs battery serious when still can lead to crash. Because the video memory work in abnormal frequency, higher frequency only makes the work become unstable, especially in reading and writing data can easily occur when mistakes. At this point, we just need to reduce or reply to the default frequency can.
Of course, the above claim we spent in laptop computers take screen of the most basic method of fault, if after commissioning fault is still, we should turn from aspects of the hardware. Is my personal experience, the emergence of laptop computers take screen phenomenon are generally hardware problems, the software problem is in more compatibility.

Three, LCD line contact undesirable
This is the first step we check the hardware toshiba pa3191u-2bas battery. Take screen, you appear irregular phenomenon, or in the pat and, on the surface of the keyboard after fault disappear, this is often due to signal to interface with the contact LCD caused by poor results. We only need to put tight corresponding interface problems can be removed.

Four, the oxidation reaction
Generally this is as laptop computers in the bad environment or use for a long time after the results of the easy appeared, processing, we will first LCD line interface, take it out of the joints with eraser gold finger, and is used with a small amount of the Toshiba pa3191u-2brs battery interface with no water alcohol clean cotton, the purpose is to remove the oxidation reaction or dirt produce because of the contact undesirable phenomena. After treatment, again will line to connect well, check whether put tight can.

Five, the video memory problems
Because part of the laptop computer toshiba pa3191u-3bas battery graphics with Dynamic Video Memory Memory Technology (i.e. DVMT, Dynamic Video Memory Technology), USES part of the Memory capacity allocate Memory for Video card. In the actual operation process, may be due to memory the internal structure damage, when selecting this part as to the video memory, and the video memory chip in exchange data are often go wrong, which led to the screen, you spend, even crash phenomenon. In that case, we can use the replacement method, and replace the same specifications of memory for inspection. Of course, if the video memory is the integration of on the mainboard, we can only be repaired.

Six, capacity problems
RAMDAC (Random Access Memory Digital-to-Analog Converter) and filter capacitor is to decide the picture quality stand or fall of video card two important factors.Toshiba pa3191u-3brs battery And the whole filter circuit work quality and capacitance quality is the value of each other, when using inferior capacitance or because the capacitance itself characteristic ability falls, spend screen, you appear phenomenon is inured to the weird. In the solution, we could start using a multimeter to check that there was a problem the capacitance, then use the same specification replacement, this problem will be solved.

Notebook HDMI have what use

Problems added: notebook HDMI have TOSHIBA Dynabook Satellite T20 173L/5 Battery what use, notebook HDMI and VGA interface have what distinction, that a better interface, HDMI and VGA interface can be mutual conversion?

The answer: HDMI interface is a kind of new hd video transmission interface, support the HDMI with such as liquid crystal displays or external LCD TV equipment such as price than does not support higher than some of the HDMI,TOSHIBA Dynabook Satellite T30 160C/5W Battery HDMI video support in high definition will be far better than VGA, early VGA interface even 1920 * 1080 resolution are unable to support.

But now the laptop graphics CARDS technology promotion, VGA interface can also support 1920 * 1080 resolution, but in the quality of the image transmission was surely not the HDMI, and at the same time for high resolution refresh rate problems,TOSHIBA Dynabook Satellite T30 166E/5W Battery such as some 3 D movie screen format requirement can be 120 Hz refresh rate, but with VGA interface'm afraid I can't reach, HDMI and VGA about the conversion of the mutual conversion problem, can achieve through adapter, but as a result of two kinds of technology, after converting is just to solve the problems in the interface on, in turn VGA quality whether HDMI and VGA or turn can only achieve VGA HDMI standard..

The above is the image problem, HDMI another characteristics is the sound signal and image signal integrated together all transmission, which means that if the use is to have a HDMI notebook, unless you need to use TOSHIBA Dynabook SS M35 166S/2W Battery common audio interface, otherwise can't separate use audio interface. HDMI output graphics CARDS are support built-in independent audio chip, and on the main board of the audio chip is different sound card, the two can separate Settings.

Suggestions in laptops to buy it if you can choose to have HDMI notebook, so in external equipment may use.

The following simple example of a HDMI application:

And compared to the desktop, laptop computer TOSHIBA Dynabook TX Series Battery in the performance of the gap has more and more small, but of liquid crystal screen display size but fell far cannot and compared the desktop. On the other hand, with the big screen LCD TV gradually came into thousands of families, a new application forms and quietly popular computer-the sitting room, also named HTPC.

The biggest advantage is can HTPC network downloaded movie, TV output to admire the liquid crystal TV, equipped with large size, and the width of the screen LCD TV, the mainstream of the video show will be opened to the effect of shocked me to present in before the user, the laptop LCD screen viewing experience is that not possible.

We need to do is to video signal and audio signal output to the liquid crystal TV respectively, below we come to TOSHIBA Dynabook TX/3514CDSW Battery talk about video signal first. At present, can achieve good image output interface including VGA and HDMI (S terminals, DVI has faced out). One of the most common VGA interface, but it can only transmit analog signals, quality of the quadrature can only say, suitable for the hd video broadcast (that is, the network of the most common RMVB format movie).

And now has HDMI notebook have mass listed, the user TOSHIBA Dynabook TX/66E Battery can directly through the VGA or HDMII to achieve video output, at this time, we also need to set the audio signal output to LCD TV. End of shuttle notebook earphone interface, the other end of the connection mode and divided into several, depending on the liquid crystal TV corresponding interface type, but related cable are easy to find.
