How to Fix a Glitch TV Screen

Usually, a glitch TV screen is caused by issues with the content you’re watching or the video input cable. The following steps will guide you to pinpoint and fix the glitch with your TV screen.

1. Turn off your TV and turn it back on

Turning off your TV and turning it back on is the first thing that should come to your mind when trying to fix glitch screens, including your TV screen.

So, turn off your TV as well as any other connected input device(s). Then, turn them back on.

2. Unplug your TV and plug it back in

The majority of TV cable connections can be plugged in or plugged out with a tug on the cord. It’s easier and faster than the ancient, screw-in RF connectors on CRT tube televisions. However, cables can get loose easily.

So, check all the video cables such as the power cables connected to your TV and your input devices. Unplug each cable and push them firmly inwards to make sure they’re properly connected.

3. Reset your TV

Resetting your TV can also help in fixing your glitch TV screen. However, the steps to do this vary by TV brand. So, follow your TV’s manual to do this. 

And if your TV came with a reset button, then press it down for at least 20 seconds until your TV screen becomes black. Immediately after your TV finishes booting, check if the issue has been fixed.

4. Check for damaged cables and connectors

Check that the video cable(s) and connectors are not damaged. Analyze the cable’s length for gaps and cuts in the plastic preserving the inner wire.

Check the connector for bends, odd discoloration, and dents. If the cable appears to be damaged or shows any sign of being damaged, replace it.

5. Examine the video source

Playing a live event or recorded video may result in a glitch TV screen. If this is your case, examine the video source. To get this done, try playing the video on another device—a smartphone or PC to see if it will keep flickering.

If it keeps flickering, then the problem is from your video. So, try to change the file format. If it doesn’t work, you cannot do anything else about it. It means your video is corrupt.

6. Check that the connected cables are compatible

Wrong and incompatible cables can cause a glitch in the TV screen. So, be sure that the right cables are connected. You cannot connect a cable using the wrong standard. They won’t fit because the connectors differ physically.

But, modern display standards such as DisplayPort and HDMI have many revisions. So if a cable is made to the standards of an older revision, it may not work with a new device. 

Find a label printed on the connector or along the length of the cable’s cord at each end of the cable. If you see a label, use a search engine to check for the cable type and specifications.

But if you don’t find a label, you could use a different cable that you know works. And if you don’t have one, buy a new cable.

7. Turn off energy efficiency mode

A TV energy efficiency feature may cause a glitch on the screen. If you enable this feature, it turns off some of your TV’s settings to maximize the energy power.

Turn it off. To do this, go to Settings on your TV. Find the option called Energy Saving or Power Saving, then toggle off the switch. After doing this, reset your TV and see if the issue has been fixed.

8. Check your TV hardware

If there’s still a glitch on your TV screen, it may be that your TV is having some hardware problems. However, we don’t advise you to change your TV’s internal hardware since it’s meant to be done by a professional technician.

If the aforementioned solutions didn’t work, contact your TV’s customer service and request support. Or take it to an authorized repairer if your TV is under warranty.

9. Check your WiFi router

A poor WiFi router connection can also lead to a glitch in your TV screen. In such a case, reset your router or take it closer to your TV for a good connection. If your TV is an older one that doesn’t have an internet connection, try taking the router far from it.
