My monitor screen is completely black, even though it is powered onIs everything firmly plugged in? A loss of video signal will cause the monitor to go black and then turn off entirely. It is easy for cables to become loose and not firmly connected, especially if you are using a mobile system. Please check to make sure everything is securely plugged in.

Your monitor possibly has TRU-Vu’s Dim-To-Black feature which allows you to control the screen’s brightness and contrast by pressing the arrow keys in the menu. The reason it has gone completely black could be because the dim-to-black was turned all the way down. Press the arrow up to the right to raise the brightness again. If this does nothing, try pressing the left arrow keys.

How do I know if my monitor is really showing true 4K video?Make sure that that the signal you are sending is 4K resolution (3840x2160). You can test this by pressing the monitor’s Menu button. The monitor’s Menu screen will display the incoming video resolution and timing in the top-right corner of the screen.

My touch screen is not working.All touch panels must be connected to a computer via USB or RS232 cable. This allows the touch panel to communicate with the computer.

My touch screen is not registering correctlyAll non-HID compliant touch panels will need to be calibrated during the initial start-up and may need recalibrating at some other point in the future. This is accomplished via the touch panel software installed on your computer. For a detailed walk through, please contact us.

Prepare the screen by turning it off and wait until it is cool to the touch. Cleaning warm or hot screens makes it more difficult to clean and can even damage the screen.

It is always recommended to spray the microfiber cloth first, then clean the screen with the moistened cloth. Do NOT spray the monitor screen directly.

For heavier duty cleaning, create a solution of 80% alcohol mixed with 20% water and use the damp, not wet, cloth to clean the screen and panel surface.

I need to clean my monitor screen (with protective glass)We highly recommend WHOOSH Screen Cleaner. It is 100% natural, non-toxic, and environmentally friendly. You can also use any standard glass cleaner.

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.

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.

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.

After a long, hard day, you finally sit down to catch up on your favorite show. But when you hit the power button on your remote control, your TV screen stays black! You try pressing the remote’s power button again and again from every angle, but still, your TV has no picture. If this sounds familiar, you’ve likely fallen victim to one or more TV screen issues.

What causes a TV screen to go black? Software issues, loose connections, or backlight problems are usually behind black TV screens. Learn about each of these causes and get tips for troubleshooting them so you can get back to relaxing with your favorite TV shows, movies, and video games.

If your TV screen is black and there’s no sound, you’ll want to check for an LED light or a small indicator light that tells you the TV has power. If there is no power to the TV while it is plugged in, there may be an issue with the outlet or fuse box in your home. However, if the TV is on but the screen is black, the problem could lie with your TV’s software.

Unplug the TV from the wall, and, if possible, remove the power cord from the back of the TV to perform a soft reset. Wait 30 seconds, and plug the TV back into a working outlet to test it again. If you’re still having screen issues, you might want to bring in an expert — they’ll know how to fix your TV’s black screen.

If your TV screen goes black but the sound still works, the first thing to check is the input source to ensure it is turned on and operating correctly. This includes external devices like cable boxes, video game consoles, laptops, and streaming devices. Once you’re sure the input source is working properly and you have the right input settings, check the cable connections. In many instances where the TV screen is black but the audio works, poor cable connections could be the issue.

Whether you’re working with an HDMI cable, RCA (usually yellow, white, and red cables) set up, or another type of connection, you need to ensure the cables are seated properly and firmly into their connection ports. With a good connection, the cable shouldn’t feel loose or easily disconnect when pulled on or moved around. If all your cables have a snug fit but the problem persists, try connecting the device to another TV. If your TV screen is still blacked out, you may need new cables.

Some TV displays, such as LCD screens, use a backlight to illuminate the picture. If the backlight burns out or stops working, it will result in a blank TV screen.

To check your TV’s backlight, make sure your TV is on. Then, turn off the lights in the room and shine a flashlight on the screen. If you can see a picture with the flashlight, then your TV’s backlight is likely burnt out.

While you might be eager to learn how to fix a black-screen TV, a broken backlight does not come with an easy solution. The backlight will need to be replaced, and it’s best to get help from a professional with this task.

You’ve run all the tests, checked all the ports, and ensured your TV has power, but your TV screen is still black! There could be a more complicated (and expensive) issue, so it might be time to ditch your old TV for an upgrade.

Performance issues may occur if there is any type of damage that is caused to the display cables or the LCD screen. LCD screen may show that symptoms like LCD screen stops working, work intermittently, color mismatch, flickering, display horizontal or vertical lines if there is damage to the display cables or the LCD screen.

Dell monitors provide a self-test feature check (SFTC) and an integrated self-test (BIST) or integrated diagnostic (BID) tool that helps determine if the screen abnormality you are experiencing is an inherent problem with the Dell monitor or with the video card (GPU) and computer settings.

When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry image, horizontal or vertical lines, color fade, it is a good practice to isolate the monitor by running a diagnostic test on the Dell monitor.

NOTE: Self-test feature check (SFTC) helps check if the Dell monitor is working normally as a stand-alone device. To check for screen abnormalities such as flickering, distortion, clarity issues, fuzzy or blurry image, horizontal or vertical lines, color fade, and so on, run the integrated self-test (BIST) or integrated diagnostic (BID) test.

Dell monitors can be reset to factory default settings using the on-screen display (OSD) menu. This can be accessed using the buttons or joystick that is available on the Dell monitor. For step-by-step instructions to reset a Dell monitor to factory default settings, see the User Guide of your Dell monitor at the Dell Manuals website.

If you find that the Dell touch-capable monitor is unresponsive to touch or touch works intermittently, you can try some common troubleshooting steps to help fix the issue.

If the diagnostic tests on the Dell monitor and video card (GPU) passed, it is most definitely an issue that is related to software that is installed on your computer. If the above troubleshooting steps did not resolve the issue, to restore your computer to factory defaults as a last resort.

If you are having issues with a blue or blank screen on your 3D printer, it can be pretty frustrating, but there are a few ways to potentially fix this.

To fix the blue or blank screen on a 3D printer, make sure your LCD cable is connected to the correct port on your machine. You also want to check that your voltage is set correctly based on your region. Changing SD card can help if it is damaged. Reflashing your firmware has worked for many people.

Keep on reading to get more methods to try and important details behind fixing your blue or blank screen, so you can resolve this issue once and for all.

The blue or blank screen on your 3D printer’s LCD panel can appear due to a number of different reasons. I’ll go through all of them below to cover the possibilities and help you quickly get back to 3D printing.

You need to do the following in order to fix the blank blue screen of your Ender 3 3D printer. We’ll first focus on the hardware end of this issue and then get to the firmware part.

One common reason why the Ender 3 can show a blue screen is due to not plugging in your LCD cable in the correct port on your Ender 3. There are three LCD ports that you’ll see on the Ender 3, so ensure that you are using the third port (on the right) to get it working correctly.

The connector should be named EXP3 and it’s keyed so you can only put it in one way. In this step, you also want to unplug the LCD screen altogether and plug it back in.

If your Ender 3 screen isn’t turning on at all, connecting to the right port should usually fix this. Also, you can check whether the cable has come loose from the mainboard.

Double check what voltage you need to set based on where you are living. This is based on your power grid. Many users don’t realize this and end up experiencing a blue or blank screen when trying to use their Ender 3.

Some people have reported that they were using an incorrect voltage for their 3D printer that not only displayed a blank screen on the LCD interface but blew up the power supply as well a little while later.

Several people experiencing the Ender 3 blank blue screen have reported a common fix in regard to their SD card. They were actually using a fried SD card that had stopped functioning and was instead causing the LCD screen to go blank.

Some people have had the screen start working again by turning it off, unplugging everything, leaving it alone for a few days and plugging it back in. This is potentially a temporary fix though because someone who tried this ended up buying a new motherboard.

If you experience some kind of glitch in your 3D printer screen, it’s usually do to a cable or wiring being slightly broken, or potential overheating. It could also be a board issue where you should reflash the board. I’d recommend checking your firmware and ensuring you are using the right display.

Many users have experienced a blue or blank screen due to the firmware, whether it hasn’t been flashed properly, they had an error occurred in some of the main configuration files, or you accidentally flashed it without realizing it.

Older Ender 3s didn’t have the new 32-bit motherboards which can be flashed simply by inserting an SD card with the correct file on it. People reported accidentally flashing their firmware and receiving a blue screen afterwards.

I’ve read around about users who got into contact with either Amazon or Creality’s customer service and have been sent a new motherboard, LCD screen or cables to get their screen working again.

If your Ender 3 (Pro) still gives you the blue screen after the firmware update or it isn’t letting you update the firmware in the first place, then this is a good sign that your mainboard has stopped working.

Users who have encountered an unsolvable Ender 3 Pro blue screen of death decided to opt for this mainboard and found it booting up the LCD screen perfectly.

One strange strategy that worked for one user to fix the blue screen on their Ender 3 was to turn off the 3D printer and manually push the print bed back with a little pressure to have the LCD screen light up.

Shattered the OLED screen on my iPhone XS. Went online searching for a replacement screen. There were many cheaper LED replacement screens available. Many of them stated that some functions originally on the iPhone would be lost after the screen was installed. I found TECHXS who offer a direct replacement OLED screen for the iPhone XS. It was more expensive but I was willing to pay the extra for a quality screen to get the phone back in service. I also ordered one of their high quality glass screen protectors to install after the new OLED screen was in place. The parts arrived quickly and well packaged. Upon inspection, everything was in perfect condition. The included tool kit was top quality. All metal screwdrivers and better plastic spudgers and picks. A nice pair of all metal angled tweezers are included. The installation was one of the easiest that I have completed on an iPhone. The TECHXS video is very informative. I highly recommend watching it before performing a screen replacement. A new gasket seal was included to make a new water resistant seal between the new screen and the case. After the install, the iPhone powered right on and everything functioned as before. The text and pictures are crisp and clear. The colors are vibrant and true. I am completely satisfied with the OLED iPhone XS replacement screen from TECHXS. I am one that reads many reviews before I make a purchase online. TECHXS has many positive reviews. I highly recommend purchasing a new replacement screen from TECHXS. If you are on the fence about spending the extra money, avoid the frustration of inferior products and buy a top quality screen from TECHXS. FYI, I received nothing for my positive review. When I receive a quality product, from a good company, I try to share my experience with others.
