A Comprehensive Guide on How to Turn On-Off LED Screen Correctly

If you own an LED screen, you probably are aware of the incredible investment that was made to get it. At the same time, you should be aware of the responsibility of operating your screen properly. 

With so much to do and watch, it can be pretty tempting to just turn your LED screen on or off willy-nilly whenever you want to. But is that right? In this article, we will look into the proper ways to turn your LED screen on and off, as well as a few other things you might need to know. 

Understanding LED Screens

When operating, LED screens work primarily based on the principle of electroluminescence. At the same time, they have the following working principle:

Semiconductor Materials: These are tiny light sources that are usually made from materials such as gallium arsenide (GaAs), gallium phosphide (GaP), or gallium nitride (GaN). 

Combining In The P-N Junction: Every LED comes with a p-n junction. Basically, this is where positively charged and negatively charged materials are allowed to combine. 

Building The LED Screen: Your LED screen will come with different individual LEDs that are properly arranged together. 

Finding The Right Resolution: It’s also important to be aware of the distance between adjacent pixels – a metric known as the pixel pitch

Brightness Control In The Long Run: Your LED screen will also need driving electronics that would allow you to properly control the color and brightness of each of the LEDs.

The Importance of Properly Turning On and Off LED Screens

The process of turning your LED screen on or off can be pretty finicky. In most cases, you just flick the thing on and turn it off when you feel like it. But, this haphazard action can come at pretty steep consequences.

Amongst others, here are some top reasons why you want to make sure that your LED screens are properly turned off or on. 

Preventing Any Damage: Like every other electronic device, an LED screen is very susceptible to damage if there is a fluctuation in power. By turning your screen on or off properly, you can make sure that there are no sudden spikes in voltage that can harm any of its internal components.

Keeping It Working For Long: Generally, LED screens have a short amount of time when they work. So, it only makes sense that you use your screens well to ensure that you can make as much from them as possible. You can reduce the operating hours, cut down on wear and tear, and prolong how it works.  

Improving Energy Efficiency: Although you get a considerable amount of energy efficiency from LED screens, turning one off or on haphazardly can increase their electricity consumption. And in the long run, you will be racking up more energy costs.  

Holding Off Image Persistence: If you notice an LED screen displaying a static image for long, then it could end up leading to screen burn-in or persistence – a situation where you see ghost images even after the actual image being displayed has changed. You can prevent this with a proper screen turn-off sequence, thus protecting the longevity of your screen.

General Better Performance: One of the underrated benefits of turning off your LED screen properly is that it helps to reset its internal components. Over time, you’ll find that this works in preventing things like screen flickering and color inconsistencies.

It Also Helps The Environment: Turning your LED screen on and off the right way also aligns with general environmental sustainability efforts. As you cut down on energy consumption, you will be able to reduce your carbon footprint and optimize environmental conservation to a considerable degree.

Preparing to Turn On Your LED Screen

So you’ve decided to take things easy with your LED screen and turn it on and off the right way. But, how do you know what to do? 

Generally, the assumption from most users is to simply turn the screen on or off and leave it be. But, this doesn’t always work out the way you might hope. To that end, you want to consider the following: 

Read The Instruction Manual

First and foremost, you want to spend enough time going through the owner’s manual. By doing this, you can ensure that you keep tabs on all of the interesting details that you might otherwise have missed. 

The importance of reading the instruction manual is simple – LED screens come in different types, all made by diverse manufacturers. So, the method for turning one screen on or off might not necessarily be the same method that works for the other. Knowing how to go about things the right way will help you in the long run. 

Remember These Safety Tips

At the same time, you want to make sure you have your eye on some of the following critical safety nuggets as you prepare your on-and-off sequence: 

  • Check the electrical connections. This way, you can avoid electrocution
  • Don’t underestimate the power of having a solid backup power supply

Troubleshooting Common Issues

Although the technology behind LED screens has expanded significantly, these are still tools. And it means that when they work, the chances of you noticing issues are pretty high. So, what are the common problems you might notice, and how do you solve them? 

Your Screen Not Turning On 

  • For this issue, your first point of call is to check the  power source and make sure the screen is plugged in well
  • You can check the cables and connectors too, and maybe even test them with some other device  
  • Also, heck for indicator lights to see if the screen is getting enough power

The Display Not Showing

  • Make sure the connection with the input source is strong, and that it is powered 
  • Verify that the video cables – HDMI, DisplayPorts, etc – are secure and connected right
  • You can also connect the screen to a different input device to see what the issue might be

Flickering Images On The Display 

  • The issue here is most likely the video cables, so check them for damage
  • Tweak the refresh rate and image resolution settings to make sure they match that of the  LED screen
  • Update  your graphic drivers, and make sure the screen isn’t exposed to any form of interference
  • If the problem doesn’t stop, then it might be worth contacting the manufacturer

 Dead Pixels On The Screen’s Corner 

  • If you want to identify dead pixels, you can use special software or a pixel test pattern
  • You could also try to revive them by applying some pressure to the affected area with a soft cloth
  • If the pixels remain, then contacting your retailer or the manufacturer will most likely be your best bet 

Image Burn-In

  • To prevent this, try not to display static content for too long in the first place
  • Also, have sleep mode features for your LED screen. This helps to minimize the risk of burn-in too 
  • If you have to show static content for long, then cut down your screen’s contrast and brightness
  • If burn-in still occurs, then you can show dynamic content for an extended period to mitigate it over time

Inconsistencies Or Casting With Color 

  • Set the color settings on the screen with custom calibration tools or external software
  • Make sure the screen isn’t exposed to direct sunlight or other light sources that might affect the color 
  • Tweak both the white balance and color settings to make sure you get the right color reproduction levels

Problems With The Audio 

  • Make sure the audio cables are connected to the screen and the input device 
  • Change the settings on both the screen and the input device to make sure they are not too low 
  • Like it is with video, you can test the audio output with different sources to make sure you find the source of the issue 
  • If the issues persist, then the manufacturers would be in a better position to fix it


Having and purchasing an LED screen in itself is not enough. As you operate the screen, you will find that it’s also important to make sure that you turn it on and off the right way. If you don’t, there are several channels through which the screen could get damaged, and you’d only have more of a headache.
