Display a black screen how to solve

We often monitor the forums or other network in the way users see release on the "display a black screen" posts, which relate to the vast majority of mainstream brands currently on the market display products, the model in particular is abundant. So what are the factors which make the LCD screen is blank it?

Solve Step one: now most LCD monitors, especially the large-size LCD monitors are equipped with D-Sub and DVI-D interface, and some models even added more interface types, so when you reconnect LCD monitors, LCD monitors The IC chip is sometimes not automatically recognized signal source. Some users in the use of D-Sub interface, do not restart the operating system, the signal input interface directly replace DVI-D, even though LCD IC circuit have the automatic signal search function of the input source, but sometimes the chip is still in the switch enough "smart", search no input signal, then we need to adjust it manually. When the input signal through the DVI-D interface inputs, while the LCD monitor IC chip will input source selection in D-Sub interface, the screen of course can not reveal any information on the screen, thus showing all black, which is also known a lot of friends as "black." At this point, we press the "Switching input source" button (usually the SOURCE or INPUT button), so that the IC chip re-selection.

Some LCD monitors and no dedicated button to switch the input source, but they will in the OSD menu provide this functionality. When you select the correct input interface, the display will show the normal screen.

Step two solutions: Some users reflect their lcm module monitor does not have a black screen phenomenon, but intermittent black screen, sometimes black high frequency. This problem also has graphics and other host hardware problems, but do not rush to it that the host hardware. First we need to carry out a preliminary assessment of the fault, do not do any checking in the case, the failure is due to the liquid crystal display or other host device. We recommend consumers the best replacement of a normal host SPIDERS display, if the display does not fail, it indicates that the previous host fails; If the monitor still has the above phenomenon, it may be a problem with the display itself.

Solve Step Three: There are some users reflect themselves in the process of playing the game, the LCD display will suddenly appear blank screen. Most of the reasons for this phenomenon, there are two: the first one is referred to in the previous case, graphics and other host hardware part is damaged; Another possibility is the game and the operating system or the graphics card driver produced a conflicts. Although the game program and the operating system, graphics card driver produces relatively small chance, but this is sometimes still occur. Previous detection methods and time are identical, both the first determine whether the malfunction of the graphic lcd display module, and then one by one starting from the host start address.

If the test result is indeed the final LCD problem, then it should go to the respective brand service center for maintenance and inspection.
