lcd screen not displaying for sale

Liquid crystal displays (LCDs) are the most widely used display technology. Their applications cover TV, mobile phone, appliances, automotive, smart home, industrial meters, consumer electronics, POS, marine, aerospace, military etc. LCD screen display problem can occur for several reasons.

Effect of environmental conditions on the LCD assembly. Environmental conditions include both the effects of temperature and humidity, and cyclic loading.

Effect of manufacturing process. With the development of LCD for more than 40 years and the modern manufacturing equipment, this kind if defects are getting rear.

Common failures seen in LCDs are a decrease in screen contrast, non-functioning pixels or the whole display, and broken glass. Different kinds of LCD display problem need to have different kinds of fix methods or make the decision not worthwhile to repair.

Broken glassIf you accidently drop the LCD and you find it broken on the surface but the display still works. You might just break the touch panel; you can find a repair house or find a youtube video to replace the touch panel. If you find the display not showing, especially you find the fluid leaking out. You need to reply the whole display modules.

Dim LCD displayLCD can’t emit light itself. It uses backlight. Normally, the backlight is not fully driven, you can increase the LED backlight to make a dim LCD display brighter. But if you LCD display has been used for a long time, it is possible that the LED backlight has to be the end of life (not brightness enough) if you turn on 100% backlight brightness. In that case to fix LCD screen, you have to find a way to change the backlight. For some display, it is an easy job but it can be difficult for other displays depending on the manufacturing process.

Image sticking (Ghosting)Sometimes, you will find the previous image still appearing at the background even if you change to another image. It is also called burn in. This kind of failure doesn’t need to repair by professionals. You can simply shut off the display overnight, this kind of problem will go away. Please do remember that displaying a static image for a long time should be avoided.

LCD has white screen – If a LCD has a white screen which means the backlight is good. Simply check your signal input sources which are the most causes. It can also be caused by the display totally damaged by ESD or excess heat, shock which make the LCD controller broken or the connection failure which has to be repaired by professionals.

Blur ImagesAs the LCD images are made of RGB pixels, the screen shouldn’t be blur like old CRT displays. If you do see blur images, they might be caused by two reasons. 1) LCD has certain response time, if you are playing games or watch fast action movies, some old LCD displays can have image delays. 2) The surface of the LCD is made of a layer of plastic film with maximum hardness of 3H. If you clean the surface often or use the wrong detergent or solvent which cause the surface damage. To fix damage on LED screen it’s need to be changed with professionals.

My LCD screen is shown blank without any single word display on the screen, it still can print if the printer network can be set to proper wifi id. But, in this case the LCD screen is blank and showing nothing, so i can not set to any wifi id at all.

Troubleshoot a video connection from a monitor (or a TV being used as a monitor) to a desktop computer. If your computer has a built-in display, see Screen is Blank after Starting the Computer.

This document will help you determine if the blank screen is being caused by the computer hardware, the video signal to the monitor, or the monitor itself.

Make sure the monitor has power and the power light comes on when the power button is pressed. If the light on the monitor remains off, the monitor is not receiving power from either the wall outlet or the power adapter.

If you have a flat panel LCD monitor, unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor.

If power light remains off when you press the power button, either the monitor is not receiving power or the monitor is defective. Check all the following items before attempting to service or replace the monitor:

If you do not hear noise from the fans and the power lights on the computer are not on, the problem is related to the computer, not the monitor. To troubleshoot a computer that does not start, see Computer Does Not Start.

At first setup, or under certain signal conditions, the monitor might not be able to switch to a new display resolution. Do not shut down or restart the computer. Instead, reset your monitor. If you need instructions for resetting your monitor, search the HP support website. Go to HP Customer Support, and follow the instructions to find your product.

Some monitors do not have on-screen messages but instead use the lights to indicate no signal. When you disconnect the cable, instead of an on-screen message, the light turns amber, indicating that the monitor lost signal and is working properly, but is out of range, or not receiving the signal.

Connect the computer to another monitor to determine which device has the problem (the monitor or the computer). If you do not have an extra monitor, temporarily connect the computer to another monitor for troubleshooting purposes.

If the newly attached monitor does not display anything, disconnect the cable and continue to the step to Inspect the video cable and video connectors for damage.

If the new monitor works, the original monitor or its cables are faulty. Try connecting the monitor with a different video cable. If the monitor still does not work, replace the monitor power cable. Replace or service the monitor if it still does not turn on.

Do not remove the video port cover. If your computer came with a graphics card, HP may have installed a plastic cover over the video port attached to the motherboard. Most PCs can use graphics from the graphics card or the motherboard, but not both at the same time. If you remove the plastic cover to connect a monitor (VGA or HDMI), the video will not work unless the graphics card is removed. The better solution is to connect an adapter to make the connection.

Gently press down on the outside edges of cards and memory modules that are inserted into the motherboard to better seat them. Do not apply too much pressure.

If the monitor still displays a black screen or displays a No signal message, the video hardware may be faulty and needs to be replaced or serviced. If the monitor displays the first startup screen but then goes blank, continue to the next step.

Use this step to configure Windows to use a display resolution that is compatible with the main monitor device. In order to perform these steps, you must connect the computer to another working monitor. If you cannot view the first startup screens, skip to Replace the graphics card or have the hardware serviced.

Use the following steps to change to a compatible display resolution and color depth setting from a standard graphics mode. For flat panel LCD monitors, set the display resolution to the monitor"s native display resolution.

If Windows was recently upgraded, Windows might be starting up into a Power Saving state and producing the blank screen before it loads. After Windows loads (about 2 minutes after turning on the computer), press the power button briefly or press the Suspend key on the keyboard to see if the computer comes out of a suspended state. If the computer opens into a suspended state every time the computer is started, use the following steps to disable Power Saving in the BIOS.

As the most common display equipment in our daily life, the monitor has been closely related to our work and entertainment. For consumers now, the highest level of attention or 1000 yuan display, but now the display market products and brands are numerous, a lot of products in the name of low-price display banner, but in fact, the quality of display products is not up to standard.

When choosing a monitor, we tend to pay too much attention to the parameters of the screen, the understanding of the internal structure of the monitor can be said to know nothing. For many monitor users, it is rare to have the opportunity to disassemble the monitor. Compared with computers, notebooks, and other products, the internal structure of the monitor appears more mysterious.

Because now the heat of the e-sports display is very high, many do not have the performance and parameters of the display e-sports and low double banner to deceive consumers, improve sales, so the author also wants to remind the majority of consumers in the purchase to pay more attention to these points, to avoid being cheated.

First of all, the first step is to remove the frame of the display. Here we need to say that many people do not easily remove the display by themselves, because the frame of many displays is better sealed. In the process of dismantling, it is easy to damage the buckle and cause irreversible damage.

After looking at the internal structure, let’s take a look at the gap between the main control circuit board. A cheap display IC circuit board design is very simple, many components are fixed with hot melt glue, and the solder joints on the circuit board are very rough poor womanliness. Compared with the Samsung display molding, components arranged neatly for the circuit board, such workmanship is indeed very pit, simply can not guarantee the service life of the display.

The image below shows the monitor. I had worked in a computer company for many years the computer test, this belongs to the screen light-leaking before assembly will be selected, it belongs to the unqualified products, but the company also spent money, after all, so will use all the products selected defective assembling, made “machine” sales promotion, the price of the advantage of this machine is very low, often 100 yuan, the Sale price is likely to be 10 yuan, after the department of the “repair”, is not hard to find professional and technical personnel, such as poor deformation, the distance between the two parts, different color, light-leaking, screen impurities, scratches (by coating treatment is generally not easy to find, after a long time away you’ll think is their careless); Laptops, for example, are particularly concerned about appearance and can use alcohol to wipe the case.

Then I checked the Internet for information about the panel used on these cheapest monitors. Searches the major panel inquiry website, can not find the detailed information of this panel, it can be seen that this panel is not produced by the mainstream panel manufacturers, the quality is suspicious. And the information on the label is very simple and provides very little information.

After looking at the above series of data, we can also know the quality of this panel. Through the data, we can determine that this panel is produced by an unknown small OEM, and the quality cannot be guaranteed at all. From the materials used to build the interior to the panel selection, it’s easy to see what’s still profitable behind its low price LCD. Through the actual dismantling, the method revealed the cheap LCD screen jerry-building, quality control is not a good phenomenon. Through this dismantling comparison, we also see the gap between the brand manufacturer’s monitor and the unknown manufacturer’s monitor in the work and the material, and those unknown brands of the bottom screen have no actual after-sales service, once the product is bought out of the problem, the final is cheated by the consumer. So in also want to remind the majority of consumers in the purchase of display to consider, do not because of cheap LCD screen price and bring more trouble to their own.
