【 Weak current College 】 LCD mosaic screen maintenance for ten tricks---Power By 【 China power house network 】

When buying a flat mosaic screen, how the hell can extend its maintenance service, achieve cost-effective? LCD experts offer advice to everyone:

The first trick: having problems is not self assembling flat mosaic screen

LCD regardless of what happens, prohibition of self assembled flat mosaic screen (special is interested in more general and DIY), once suspected liquid crystal mosaic screen is not working properly you can find companies to help solve. Because the LCD is too delicate to precision, too (it does not like ordinary CRT LCD mosaic screen that can replace the Assembly). Because the LCD background lighting components of transformer in power off after a certain period of time still possible with high voltage 1000V (although is micro-currents), rather than professionals if treatment is not good potential components of new fault, grim, may also cause screen permanently unable to work.

Second trick: to avoid liquid crystal mosaic screen work long hours at full load

Liquid crystal mosaic screen long work very easily make certain pixel (PixelDot) overheating, exceeding the limit can lead to permanent damage. It's often called "pixel" (some media known as "black sites"). Due to the liquid crystal mosaic screen pixel is determined by the LCD, so when continuous full-load work 96 hours or more, it will speed up the aging, severe even burned. In view of this, if a user must longer work, it is best to be intermittent and let it rest for a while, or often to a different time interval changes the screen presentation content, at least when you are in a wait state, or to reduce the brightness of the screen as protected mode operation, this little effort not only can slow the aging of the LCD, and can avoid hardware damage.

Third trick: pay attention to distinguish between the LCD screen flashing phenomenon of splicing

Occasional flashes this is imitation/digital conversion unavoidable circumstances, mainly due to imitatedsignals output interface, such as the pixel clock and phase is not synchronized with the imitation of the signal output can also cause flashing phenomenon, this phenomenon is often referred to as "PixelJitter (pixel jitter). To resolve this problem, usually in liquid crystal mosaic screen has the automatic setting function, which is on the basis of an analysis of the input signal will adjust the LCD screen is the best stitching. Also available through the adoption phase (Phase), clock (Clock) two function adjusts itself. However, if you are a Flash or flashes of often obscure, it is necessary to check. If you exclude a section bad question of liquid crystal mosaic screen itself fails.

Fourth trick: to avoid LCD appeared in severely shocked

LCD screen fragile precious manifestation, impact resisting ability of the poor, even the latest products it anti-impact or far and CRT LCD mosaic screen. This is because the LCD has a lot of precision glass components and agile delicate of electric components, once be strongly impact leads to the LCD screen as well as other related parts are damaged. So be sure to avoid the strong impact of shocks. Also, do not focus on the LCD screen surface pressure, such as the finger pointing to a part of the screen (even if it is a bit of hits may produce severe local bad points to form a piece of black spots), this very easily lead to bad point increase in the phenomenon, that is why some users use for a period of time will find bad point more and more important reasons. When this happens, users themselves have no way to remedy. Therefore it is recommended that you use to develop good habits, not finger on the screen.

The fifth trick: accurate clear liquid crystal mosaic screen screen surface dirt method

If you find that there is liquid crystal mosaic screen surface dirt, you should use the exact method will remove dirt. The best use of media is soft, non-fibrous material such as cotton wool, lens paper or a softcloth, etc, and then dip a little glass cleanser gently wipe it, the prohibition of the use of alcohol a class of chemical solutions, can't use coarse cloth or paper, because such material easy to scratch. Here to remind everyone that, do not spray directly onto the clean River to show the screen surface, it is very easy to screen LCD screen inside the result within the short circuit fault, resulting in unnecessary loss.

The sixth trick: moisture is taboo liquid crystal mosaic screen

Liquid crystal mosaic screen internal design is extremely thorough, once produced by environmental wet oxidation corrosion caused short circuit, will give users bring huge economic losses. So focus on the do not allow any liquid or moisture enters LCD mosaic screen, at the same time to avoid hot and wet environments for long periods of use. Of course, if this situation should not panic, such as discovery screen surface moisture with a soft cloth to gently wipe away before you can turn on the power of work. If the moisture has entered the LCD inside must be LCD on ventilation or warm place, and let the moisture evaporated. If the situation is more severe, normal users can invite professionals help solve. Remember, in the absence of remove moisture don't let LCD power, otherwise easily lead to liquid crystal electrode corrosion, thus causing permanent damage to the LCD.

Seventh strokes: unusual it is best to use the recommended optimum resolution

If the video card with DVI robbery gang output directly to LCD Digital robbery gang, this brand new show way no pixel loss, the video output signal is perfectly visible. However, in the show is less than optimal resolution of the picture, the LCD show you two ways to show that a show is centered, such as the optimal resolution is 1024 × 768 LCD liquid crystal mosaic screen in the appearing of 800 × 600 resolution, the only one among the 800 × 600 pixels to show pictures, the shadow, such as signal resolution is one-to-one, so the picture clearly, the only regret is that the screen is too small; the other is to expand the way, is the 800 × 600 screen through the calculation of the expansion to a resolution of 1024 × 768 to appear,Because this way the processed signals correspond one-to-one with the pixel is not, although the screen is big, but rather ambiguous. No matter what kind of behavior are not ideal, so I strongly recommend the recommended maximum resolution!

8 tips: avoid prolonged show the same picture

And CRT LCD mosaic screen, LCD liquid crystal mosaic screen will work long hours of aging caused by internal or burned, particularly worse in the long term appeared the same picture. If long continuous showing a fixed content, it is possible to cause some pixels to overheat, which in turn caused internal burned, produce bad points. The damage is irreversible and cannot be repaired. Therefore we should focus on when in use: nothing to do, turn off LCD mosaic screen; if you are only temporary nothing, select screen saver. Or is the presentation screen brightness down or let the screen all white; but this only protects LCD, rear light tube still worked, so I also support direct off the mosaic screen, the same liquid.

Ninth trick: LCD liquid crystal mosaic screen screen cleaning

Baby LCD liquid crystal mosaic screen for a long time, the screen is dirty became the face, what precise cleaning method is get stained with a little glass cleanser cloth carefully wipe the stain (there is no detergent with water), wipe the intensity of light, when otherwise flat mosaic screen screen would short-circuit damage. In this process must not let the water flow to the screen and the screen box of robbery gang, avoid short-circuit Burnout LCD mosaic screen. Do not use hard towel wash the screen surface, so as not to rub the surface of the screen which affect the appearance of fluff. Clean show screen also scheduled quantitative, frequent scrubbing is wrong, it willcause some to show screen. In addition, against some won't rub off the grease stains, I have a secret, transparent, to the previous screen, then mortgage, be posted on the screen where very clean, grease stains are glued to the transparent above.

Tenth: eliminate some bad habits

The biggest bad habit is often hand juggle on screen, LCD liquid crystal mosaic screen is very delicate, several thousand dollars of liquid crystal mosaic screen do not randomly touch her. In General, LCD liquid crystal mosaic screen are relatively light, accidentally knocked over, this wasn't fooling. It is also important to pay attention to, LCD liquid crystal mosaic screen comparison of power consumption, but the LCD liquid crystal mosaic screen after the voltage of the transformer or a high level of security to be special attention; not in live situations open the rear cover of the liquid crystal mosaic screen. Even after a power failure, the retention of transient voltage is very high, the background lighting components in CFL transformers still with some high voltage 1000V. In flat panel LCD mosaic screen, only gradually consumed parts is liquid crystal mosaic screen background lighting. After the long-term use, you may find that the screen is no longer so bright, or simply is dark, it is no serious problems, as long as another new background lighting. Pay attention to, LCD liquid crystal mosaic screen this product is not in General, it is better not to handle the DIYer, better get a computer company, or specifically also grease repairing station for repairs. In short, do not use the CRT LCD mosaic screen careless trouble again demonstrates LCD liquid crystal mosaic screen.
