lcd screen not displaying supplier

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.

Troubleshooting CRTs versus LCDs begins with similar steps, but diverges due to the differing natures of the two display types. The first troubleshooting steps are similar for either display type: power down the system and display and then power them back up; make sure the power cable is connected and that the outlet has power; verify that the signal cable is connected firmly to both video adapter and display and that there are no bent pins; verify that the video adapter is configured properly for the display; try the problem display on a known-good system, or try a known-good display on the problem system; and so on. Once you"ve tried the "obvious" troubleshooting steps, if the problem persists, the next step you take depends on the type of display. The following sections cover basic troubleshooting for CRTs and LCDs.

CRTs seldom fail outright without obvious signs, such as a loud snap or a strong odor of burning electrical components. Most CRT problems are really problems with the power, video adapter, cable, or hardware/software settings. To eliminate the CRT as a possible cause, connect the suspect CRT to a known-good system, or connect a known-good display to the suspect system. It is worth noting, that older CRTs eventually wear out, and starts dimming. Common signs of a weak CRT are a dim picture, dysfunctional brightness and/or color controls, image smearing at high brightness, and in color CRTs, a tint towards a single color (Red Green Blue)

If the CRT is the problem, it is often not worth repairing. If the CRT is out of warranty, parts and labor may cost more than buying a new CRT, which also gives you better specs and a warranty. About the only CRTs we"d even consider repairing out-of-warranty are high-end 21" or larger models, and even there the economics are dubious.

Even if the CRT is in warranty, the shipping costs may exceed the value of the CRT. For example, shipping a CRT both ways can easily cost $75 or more. If that CRT is a year-old 17" model, you"re probably better off spending $100 to $200 for a new 17" or 19" CRT than paying $75 in shipping to have the old one repaired. CRTs have many components, all of which age together. Fixing one is no guarantee that another won"t fail shortly. In fact, that happens more often than not in our experience.

This is a hardware problem with one of the electron guns. Replace the CRT. This problem may also manifest as a strong color cast during normal operation that is not correctable using the normal color balance controls.

This is usually a minor hardware problem. The most likely cause is that the signal cable is not connected tightly to the CRT and/or video card, causing some pins to make contact intermittently or not at all. Verify that no pins are loose, bent, or missing on the cable or the connectors on the CRT and video card, and then tighten the cable at both ends, If that doesn"t fix the problem, open the computer, remove the video card, and reseat it fully.

In elderly systems, another possible cause is that some hardware DVD decoder cards "steal" one color (usually magenta) and use it to map the DVD video signal onto the standard video signal. Remove the DVD decoder card. If your video adapter includes hardware DVD support, or if you are upgrading to such an adapter, you don"t need a DVD decoder card.

Most modern CRTs can display signals at many different scan frequencies, but this doesn"t mean that the CRT will necessarily automatically display different signals full-screen and properly aligned. Use the CRT controls to adjust the size and alignment of the image.

This is usually caused by RF interference from another electrical or electronic device, particularly one that contains a motor. Make sure such devices are at least three feet from the CRT. Note that such interference can sometimes penetrate typical residential and office walls, so if the CRT is close to a wall, check the other side. Such image problems can also be caused by interference carried by the power line or by voltage variations in the AC power supply. To eliminate interference, plug the CRT into a surge protector. Better still, plug it into a UPS or power conditioner that supplies clean power at a constant voltage.

The CRT may need to be degaussed. A CRT that sits in one position for months or years can be affected even by the earth"s very weak magnetic field, causing distortion and other display problems. Exposing a CRT to a strong magnetic field, such as unshielded speakers, can cause more extreme image problems. Many modern CRTs degauss themselves automatically each time you cycle the power, but some have a manual degauss button that you must remember to use. If your CRT has a manual degauss button, use it every month or two. The degaussing circuitry in some CRTs has limited power. We have seen CRTs that were accidentally exposed to strong magnetic fields, resulting in a badly distorted image. Built-in degaussing did little or nothing. In that case, you can sometimes fix the problem by using a separate degaussing coil, available at RadioShack and similar stores for a few dollars. We have, however, seen CRTs that were so badly "magnet burned" that even a standalone degaussing coil could not completely eliminate the problem. The moral is to keep magnets away from your CRT, including those in speakers that are not video-shielded.

An incorrect yoke may have been attached to the CRT. Unless you have a lot of spare time on your hands, this is usually not worth fixing. Replace the display.

If your LCD displays no image at all and you are certain that it is receiving power and video signal, first adjust the brightness and contrast settings to higher values. If that doesn"t work, turn off the system and LCD, disconnect the LCD signal cable from the computer, and turn on the LCD by itself. It should display some sort of initialization screen, if only perhaps a "No video signal" message. If nothing lights up and no message is displayed, contact technical support for your LCD manufacturer. If your LCD supports multiple inputs, you may need to press a button to cycle through the inputs and set it to the correct one.

Unlike CRTs, where increasing the refresh rate always reduces flicker, LCDs have an optimal refresh rate that may be lower than the highest refresh rate supported. For example, a 17" LCD operating in analog mode may support 60 Hz and 75 Hz refresh. Although it sounds counterintuitive to anyone whose experience has been with CRTs, reducing the refresh rate from 75 Hz to 60 Hz may improve image stability. Check the manual to determine the optimum refresh rate for your LCD, and set your video adapter to use that rate.

First, try setting the optimal refresh rate as described above. If that doesn"t solve the problem and you are using an analog interface, there are several possible causes, most of which are due to poor synchronization between the video adapter clock and the display clock, or to phase problems. If your LCD has an auto-adjust, auto-setup, or auto-synchronize option, try using that first. If not, try adjusting the phase and/or clock settings manually until you have a usable image. If you are using an extension or longer than standard video cable, try connecting the standard video cable that was supplied with the display. Long analog video cables exacerbate sync problems. Also, if you are using a KVM switch, particularly a manual model, try instead connecting the LCD directly to the video adapter. Many LCDs are difficult or impossible to synchronize if you use a KVM switch. If you are unable to achieve proper synchronization, try connecting the LCD to a different computer. If you are unable to achieve synchronization on the second computer, the LCD may be defective. Finally, note that some models of video adapter simply don"t function well with some models of LCD.

If the screen is displaying a full, stable image, but that image is of poor quality, first verify that the display is not connected through a KVM switch or using an extension cable. If so, connect the display directly to the video adapter using the standard cable. If that is already the case, adjust the brightness, contrast, and focus controls. If you are unable to get a proper image using these controls, the problem is most likely a clock or phase mismatch, which you can cure by taking the steps described in the preceding item.

The best way to adjust clock and phase is to use auto-adjust first. Check the utility and driver CD that came with the monitor. It may have a wizard or at least the appropriate background screens to use while adjusting phase and clock settings. If not, go to the Windows Start menu and select Shutdown. When the screen goes gray and the Windows Shutdown dialog appears, leave that dialog onscreen, but ignore it. Use the gray screen to adjust clock and phase manually. Any problems with clock and phase and any changes you make to the clock and phase settings are clearly evident on the gray screen.

Always adjust clock first. Clock is usually not a problem if you have used the auto-adjust feature of your monitor, but if you do have clock problems they will be evident as large vertical bars on your screen. Tweak the clock setting until those bars disappear. Then adjust phase. Phase problems are evident as thin black lines running horizontally across the screen. Adjust phase until the lines disappear or are minimized.

Not all analog video cards synchronize perfectly with flat panels. The gray Shutdown screen exaggerates the problem, so don"t worry if very tiny movements are visible after you"ve adjusted clock and phase as well as possible. After you"ve set the clock and phase controls for the best image possible on the gray screen, cancel Shutdown and the image should be optimized.

Your video card is supplying a video signal at a bandwidth that is above or below the ability of your LCD to display. Reset your video parameters to be within the range supported by the LCD. If necessary, temporarily connect a different display or start Windows in Safe Mode and choose standard VGA in order to change video settings.

This occurs when you run an LCD at other than its native resolution. For example, if you have a 19" LCD with native 1280x1024 resolution but have your display adapter set to 1024x768, your LCD attempts to display those 1024x768 pixels at full screen size, which physically corresponds to 1280x1024 pixels. The pixel extrapolation needed to fill the screen with the smaller image results in artifacts such as blocky or poorly rendered text, jaggy lines, and so on. Either set your video adapter to display the native resolution of the LCD, or set your LCD to display the lower-resolution image without stretching the display (a feature sometimes referred to as display expansion), so that pixels are displayed 1:1, which results in the lower resolution using less than the entire screen.

This is a characteristic of LCDs, particularly older and inexpensive models, caused by defective pixels. Manufacturers set a threshold number below which they consider a display acceptable. That number varies with the manufacturer, the model, and the size of the display, but is typically in the range of 5 to 10 pixels. (Better LCDs nowadays usually have zero dead pixels.) Nothing can be done to fix defective pixels. Manufacturers will not replace LCDs under warranty unless the number of defective pixels exceeds the threshold number.

Some people claim that leaving the unit powered off for a day or two will "erase" a persistent after-image. Others suggest leaving a neutral gray screen (like the one used for phase adjustment) up on the screen to "equalize" the display. I dunno. FWIW, I"ve seen this problem on older Samsung panels but never on the Sony or NEC/LaCie panels I use.

Again, this is a characteristic of LCDs, particularly older and inexpensive models. The after-image occurs when the display has had the same image in one place for a long time. The after-image may persist even after you turn the display off.

Transistor-based pixels in an LCD respond more slowly than the phosphors in a CRT. The least-expensive LCDs exhibit this problem even with slow image movement, as when you drag a window. Better LCDs handle moderately fast image movement without ghosting, but exhibit the problem on fast-motion video. The best LCDs handle even fast-motion video and 3D gaming very well. The only solution to this problem is to upgrade to an LCD with faster response time.

Use the brightness control to increase image brightness. If you have set brightness to maximum and the image is still too dim, contact the display manufacturer. The CCRTs used to backlight the screen have a finite lifetime and may begin to dim as they near the end of their life.

If one or more horizontal and/or vertical lines appear on the display, first power-reset the computer and display. If the lines persist, run the auto-setup function of your display. If that does not solve the problem, power the system and display down, remove the video cable, and verify that the video plugs and jacks on both computer and display ends do not have broken or bent pins. Even if all appears correct, try a different video cable. If the problem persists, contact the display manufacturer.

Since the camera can still take pictures, store them and download them OK it seems as though the fall has either loosened the LCD screen flex cable connection to the motherboard or the more likely has damaged the screen. LCD screens cannot be repaired, they have to be replaced. The supplier link is only to show the cost of the part. Just search online for Nikon D3200 LCD screen to find suppliers that suit you.

That’s probably why you need to reevaluate today. Asking the right questions during this process clarifies the conditions you need to work successfully with the LCD display supplier.

Most of the review process is about asking the right questions about your needs to the supplier. Knowing exactly what display requirements the new LCD manufacturer should meet will inform you that they should what are the functions?

There is a significant difference between the demand for 2,000 and 200,000 screens per year, not only in large quantities but also in determining whether LCD vendors can effectively meet the demand for mass-produced displays.

Whether you need a JIT order, late inventory, or less than the lead time order, you will determine what LCD display manufacturers need to use to ensure seamless integration.

Compare multiple display vendors to see how well each vendor matches your list. It’s not always about cost. If the display vendor can’t compete at your core By working with the wrong vendor, you are likely to find higher ancillary costs and higher overall system-level costs.

Are there any regional differences inpower specifications thatASUS LCD monitor supported (for example: If monitor was bought in Taiwan, can it be used in China or other countries?)

ASUS LCD monitor can support power specification: AC 100-240V. As long as within this voltage range, the display can work properly. However, please be noted that if you bought a monitor from another region, the power cord is not necessarily compatible to power outlet. Customer should replace the appropriate power cord or plug adapter in order to ensure normal power supply of the display.

VISLCD has been engaged in LCD production and sales for 9 years, and we have met many customers who shared with us that they had encountered unreliable LCD suppliers.

For example, the answer is not what you asked for, the LCD product cannot be delivered on time, the price of the LCD suddenly increases, the LCD module suddenly breaks down during the use of the product, or even the LCD is discontinued after less than 1 year of delivery…etc. In addition, there are many customers who are not sure what type of LCD supplier they are looking for.

In view of all the above, VISLCD has written this article to share knowledge about LCD suppliers and other issues related to LCD. We believe it will be helpful to LCD customers.

To understand LCD suppliers, we first need to know what kinds of LCD suppliers are available. Then LCD customers can find the right supplier based on information such as their product applications, LCD requirements and forecast volume.

LCD original manufacturer refers to the original manufacturer of LCD panel. Originated from the USA in the 1960’s, after more than 50 years of development, the manufacturers are now mainly located in China mainland, Korea and Taiwan. Among them, the Chinese manufacturers in recent years rely on the rapid scale, technology development and price advantage, has gradually occupied the main market share.

The video below is an official video presentation of the BOE display factory and Century Display (CTC), which will give you a more visual understanding of the original LCD manufacturer.

The 5.1 generation TFT-LCD line of Century Display in Shenzhen, China, for example, has been put into operation since 2008 with a cumulative fixed investment of more than $4 billion, and the cost of water, electricity, employee wages and equipment depreciation is as high as $0.5~100 million/month. The monthly production capacity is about 100,000 sheets ( 1300*1200mm/sheet). If all of them are used to produce 7-inch LCD panels, then the monthly shipment volume is up to 9,000,000 pcs. Therefore, a very large monthly shipment volume is required to meet the normal operation of the factory.

This is only the 5.1 generation TFT-LCD line, if it is 8.5 generation line or even 10 generation line or more, then the cost and shipment volume may be several times or even ten times more. It should be noted that the number of generations of LCD lines does not mean that the technology is high or low. The higher the generation, then the larger the size of the LCD can be put into production, of course, the greater the volume of shipments and investment amount.

LCD original manufacturers generally provide mainly LCD panels, but also provide COG (LCD + IC), FOG (LCD + IC + FPCA cable) and other kinds of LCD semi-finished products. Also includes a small amount of the original LCD module. But the original LCD factory will only deal with the famous brand companies directly (such as Apple, Dell, Xiaomi, etc.), or through agents to ship. And the MOQ quantity requirement is very high (generally 1,000,000 pcs/month or more), the unit price of original LCD module is also high and the degree of customization is low.

LCD original manufacturers usually have an order MOQ requirement for their agents, which translates into an LCD unit quantity of no less than 100,000pcs/month. When the LCD demand is high, this will not be a problem; but when the market is low, the agent must buy the agreed MOQ quantity of LCD from the original LCD manufacturer even if there is no customer demand for the time being. So when the low season, if your order quantity is large enough, then you may get a very good LCD panel price from the LCD agent, which may even be lower than the agent’s purchase price.

LCD module manufacturers is to purchase LCD semi-finished products (such as LCD panel, COG or FOG) from LCD agents, then purchase ICs from IC agents, produce or purchase backlight, FPCA cable and touch screen components, and then integrate all the above components into LCD module or touch LCD module. LCD module factories vary in size from tens of millions of pcs to hundreds of thousands of pcs shipped per month.

Medium and large size module factory generally get the semi-finished products are FOG LCD (also known as open cell LCD) from the original LCD manufacturers or LCD agents, and then add the backlight assembly into the finished LCD module. The advantage of doing so is that the quality is relatively stable, but the degree of customization will be much lower. Because FOG LCD already includes FPCA cable, generally speaking, the only thing that can be customized is the brightness of the backlight and the touch panel and cover glass (if needed). The rest are difficult to change, unless the customer’s LCD demand is very large.

The small and medium size module factory after years of mature development of the industry, the degree of customization will be much more flexible. The semi-finished products are mainly LCD panels, which means that the backlight size, backlight brightness, FPCA cable design, shape and PIN number, as well as the touch panel and cover glass can all be customized according to the customer’s requirements. But the MOQ requirement is higher for the backlight size. Other parts of the customization generally require LCD MOQ of at least 2,000~5,000 pcs, which varies depending on the LCD size.

Since LCD module manufactures vary in size and quality control(especially small and medium size LCD module factories), and most of the components are sourced, the selection of module factories is particularly important if customers want to buy LCDs with good quality and competitive prices.

For example, if the factory’s customers are mostly low-cost products or repaired product manufacturers, then it can be assumed that the quality of his products is not too good, LCD panels and some other components may be B-grade products, not A, can only meet short-term use.

This is essential to ensure supply. In case of supply shortage, many module factories with insufficient upstream channels sometimes cannot even start production. Because they can not buy raw materials such as LCD panels and ICs.

As the name implies, trading companies do not have their own factories, but directly sell finished LCD products from LCD resellers or LCD modules from module manufacturers. Generally speaking, the LCD prices of trading companies are relatively high and the quality and reliability are a little weaker. However, there is no shortage of good trading companies with good quality management teams and good upstream channel resources. The biggest advantage of trading companies is their flexibility, which can meet the diversified needs of customers.

2) Shenzhen has 3 types of buildings related to lcd (including other electronic products): office buildings, factories and markets. Almost all LCD panel and IC agents are located in various office buildings in Shenzhen, while component factories such as FPCA, Touch panel and backlight are located in various industrial parks in the suburbs. It is possible to find the right components and develop new products in the shortest time. Of course, there is also the famous Huaqiang bei(north) Electronic Market, a very complex place.

VISLCD was a trading company in the early days. But after nearly 9 years of development, it has developed into a combination of LCD module factory and LCD agent. The company is located in LCD base Shenzhen, China and operates in both Hong Kong and Shenzhen. We have our own module factory and have direct relationship with Century Display, LG, HKC and other LCD original manufacturers. Our main employees are also from these LCD manufacturers. We also accept all kinds of customized LCD business. Therefore, VISLCD is one of the best choices for medium-sized customers in terms of quality stability, semi-finished parts supply and customization.

Five simple words that can equate to significant LCD display challenges for you. Here’s how you can successfully address and resolve these 5 LCD display challenges:

Missed deliveries are a killer. With even just one component missing, an assembly line goes down, affecting operations, missing revenue goals and failing customers. Components often have long and variable lead times which can lead to production and subsequent delivery problems if they’re not managed quickly and effectively.

Proactively address this challenge with the LCD display provider and within your company. Internally, assure suppliers’ lead-times are accurate in your MRP. Additionally, maintain a 2-4-week buffer stock or more depending on lead-times and component scarcity.

The LCD display supplier can also carry a buffer stock for your application. Reactively, the LCD display supplier should offer expedited options. Effective display provider can pressure the upstream supply chain, adjust production schedules, ship partial quantities and accelerate shipments. Applying these solutions eliminates most delivery problems and handles unplanned customer demand (a good thing!).

Find a display provider that is prepared for and addresses obsolescence when it rears its ugly head. Display providers who are manufacturing more customized systems are more likely to work with your needs than high-volume suppliers. Understand what would cause an LCD display to become obsolete. Your ideal design partner(s) will design for obsolescence mitigation. Then, by giving a long end-of-life (EOL) notice period, the LCD display provider can react by creating safety stock, sourcing alternates and re-engineering your display around a readily available replacement. Additionally, they should plan development of a compatible replacement so your product development doesn"t need to change. Obsolescence management safeguards your product line and down the road - your bottom line.

Quality issues generally arise in a few ways. First, the LCD display"s failure to meet the performance specification as intended. This involves defining what"s required to satisfy the product"s intent and customers" needs. Next, there are the optical and mechanical aspects of LCD display manufacturing. This includes meeting dimensional tolerances and maximum defect limitations.

A supplier that manufactures to your specific needs will minimize quality issues due to their ability to bring flexibility and expertise by modifying the LCD display for your specific product, and then actively supporting ongoing product improvements.

Defining “performance” begins with the application. Who is the target market or end user and how will they interact with the LCD display? In what environment will it be used? How is it being sold or demonstrated to customers? What data does the LCD display need to convey? Must it be readable by the visually impaired?

When performance is fully understood, we can define the idealdisplay type, size, pixel density, contrast, temperature range, brightness, color gamut response time, etc. Over-specifying any of these factors adds unnecessary cost, while under-specifying will detract from the end product"s usability. Ensure performance is optimized in order for your application to be successful. It is key to find an LCD display provider who is willing to adjust and customize these particular variables and explain them to you in terms of the end user experience.

Determining the right price to pay depends on three factors. What does the display need to do? What does the display NOT need to do? And lastly, what quantity is needed? In most cases the ideal option is a custom or semi-custom display perfectly designed for its application. Despite what many think, this is often the most cost-effective solution.

Another cost challenge is system-level manufacturability. This is where display integration improvements can reduce product complexity, improve manufacturing time, and reduce system level manufacturing defects. For the most seamless LCD display integration, there are additional components such as buttons, LEDs, PCB boards, and connectors that are more efficiently integrated on the display rather than a separately assembled component. Clearly in this case, the LCD display cost will go up, but when done right, the system level cost is reduced to result in a net gain.

Lastly, you need to know system-level costs. If you’re giving up customer valued performance or functions, you"re trading market share and profitability for display savings and the net result may be decreased profit. The opposite also holds true; adding performance that is not necessary (these are attributes that the customer does not value) simply adds additional product costs.

Choosing the right supplier, based on your volume and quality needs is essential. Then implement the optimal LCD display solution with the optimal features and performance.

Apple tasked BOE with making iPhone 13 displays last October, a short-lived deal that ended earlier this month when Apple reportedly caught BOE changing the circuit width of the iPhone 13’s display’s thin-film transistors without Apple’s knowledge. (Did they really think Apple wouldn’t notice?).

According to MacRumors, BOE previously only manufactured screens for refurbished iPhones. Apple later hired the company to supply OLED displays for the new iPhone 12 in 2020, but its first batch of panels failed to pass Apple’s rigorous quality control tests. Since the beginning of this year, BOE’s output has also been affected by a display driver chip shortage.

The LCD screen is vital for operating the printer. Should you encounter any kind of trouble, such as a dead screen, corrupted text, or other issues, please refer to the guide below.

First of all, unscrew the LCD screen from the printer frame, remove both M3x10 screw holding it the LCD board in the plastic casing, and remove it from the casing. See if the problem still appears when the LCD is not pressed by the casing.

Firmware updates are necessary to keep your printer up to date. However, the installation of incorrect firmware can lead to letter corruption on the LCD screen. There"s an easy fix, though:

There is a small chance the printer"s LCD screen can glitch out by electrostatic discharge when inserting the SD card. Try to turn the printer off and on again.

This problem usually appears only on user-assembled printers. If your printer"s LCD screen remains blank or displays corrupted symbols after you turn on the printer, there is a chance it is caused by incorrect wiring. Follow these steps to fix the issue.

Double-check that all cables are properly seated and they are not visibly damaged. Depending on the model of your printer, please refer to the following guides for information on how to make sure the cables are properly connected: Einsy RAMBo electronics wiring (MK3/MK3S/MK3S+) and Mini RAMBo electronics wiring (MK2S, MK2.5, MK2.5S).

If you suspect that the LCD ribbon cables connectors are not firmly seated in the slots, disconnect the LCD ribbon cables and check the slots for any bent pins. If there are bent pins, you can use tweezers to fix them. However, be very careful not to break the pin(s) completely.

Defective pixels do not necessarily impair the performance of the monitor. However,they can be distracting, especially if the pixels are in positions where viewing quality is reduced.
