How to Fix a Flickering TV Screen

Here’s a list of possible fixes you can try to resolve your glitchy TV screen. Make sure to follow the fixes individually to identify and fix the issue. Let’s dig in.

1. Verify the Video Source Is Functioning Correctly

If you notice a glitchy TV screen, it could be due to a fault in your video source.

This occurs when the TV receives corrupted frames from a broadcast, whether you’re watching a recording or streaming online.

Unfortunately, it’s not possible to fix the video source. However, if you are streaming, resetting the router or rebooting your TV may be helpful.

2. Restart Your TV

If you’re still experiencing flickering issues, you should reboot your TV.

Restarting your TV could help you stop the glitchy TV screen. Make sure to wait for a couple of minutes before turning your TV back on.

Press The Power Button

Remember, turning on and off your TV will only fix temporary problems. You may need to move on to other fixes to troubleshoot and resolve the issue.

3. Disconnect Your TV From the Power Outlet

If powering on and off the TV doesn’t work, unplug your TV from its power source.

Unplug Your Tv

Performing a soft reset on your TV might help you resolve the flickering issue on your TV. The key here is to wait 5–10 minutes before plugging your TV back into the power outlet.

4. Examine Your Cables for Any Damage or Loose Connections

To ensure that your TV functions properly, it’s essential to check for damaged cables. Look out for damaged cords, bent wires, or loose connections, particularly if you notice flickering occurring only during specific input usage.

Double Check Your Cable Connections

For instance, if flickering happens while playing a video game, it’s worth checking all the cables associated with the console, particularly the HDMI cables that tend to break easily. Similarly, if the flickering only happens while watching cable TV, inspect the wires connected to the cable box.

Thankfully, replacing these kinds of wires is not expensive these days.

5. Inspect Your Wi-Fi Router for Interference

If you’re experiencing flickering on your smart TV, it’s worth considering the router as a possible cause.

Restart Your Router

You can try resetting the router or placing it closer to your TV, but you should avoid moving it too close. This is because routers give off signals that could interfere with older TVs.

If you own an older TV that doesn’t require access to the internet, it’s best to place the router at a safe distance from the TV screen.

6. Check for Overheating Problems

If you have an older TV, you might encounter problems like overheating, which can cause the screen to appear distorted and flickering. This issue can potentially lead to complete failure, particularly for LCD TVs.

Meanwhile, overheating on LED TVs can cause old LEDs to break down, leading to dead pixels.

While unaffected bulbs will still work, the rest malfunctioning can eventually spread across the screen, rendering the display unusable.

If you notice overheating occurring after a few hours of continuous usage, consider contacting a professional to service the TV’s cooling system.

Now, it’s worth exploring some simple reasons for overheating and learning how to fix them. Here are some useful tips to avoid overheating:

  • Keep your TV away from other sources of heat to reduce the chances of overheating. For instance, if your TV is located near other devices and vents that emit heat, consider relocating it to a cooler spot.
  • Remove any objects that may be blocking airflow, such as decorations or furniture, as they can obstruct the vents and hinder proper ventilation.
  • Clean the vents to prevent dust and debris from building up and limiting airflow, which can then cause your device to overheat.

7. Assess the Lighting Conditions in Your Room

TV screens flicker constantly, but the flicker is usually too quick to be noticeable. However, in some extreme lighting conditions, the refresh rates become noticeable, making the TV seem like it’s flickering. One solution to this problem is to either darken or brighten your room

Alternatively, you can adjust your TV’s brightness settings to eliminate flickering. While it may take some experimentation to find the optimal settings, the changes will be noticeable immediately.

8. Look for Signs of Screen Burn-In

While screen burn-in is less common in LCD and LED TVs compared to CRTs, there are still similar issues that can occur.

For instance, if an LCD TV displays a static image for an extended period, it can cause a “burn-in,” where the image persists even after changing what’s on display.

Similarly, LEDs can also experience this issue, leading to screen flickering due to inconsistent display output.

To reduce the occurrence of this problem, it’s recommended to lower the TV’s brightness, as this is often the cause of the issue. By reducing the brightness, you can minimize image persistence and increase the longevity of your TV.

9. Try Moving to Another Spot

If you own a plasma TV and notice flickering, it could be due to your viewing angle or distance from the screen. Consider adjusting your TV setup or changing your seating position to find the optimal viewing angle. By doing this, you may be able to reduce or eliminate the flickering on your plasma TV.

10. Download the Latest Firmware Update on Your TV

If you own a smart TV, it’s necessary to update it periodically. Neglecting to do so could result in subpar refresh rates and various connectivity problems. You can typically find the updates in the settings, software, and support sections of your smart TV menu.

Click On Update Now

Choose the “Update Now” option and wait for it to download and install on your TV. This should resolve most screen flickering issues experienced by smart TV users.

11. Disable Energy-Saving Settings

If you are experiencing screen flickering on your TV, it’s possible that the energy-saving mode could be the culprit. To verify if this is the case, you can try disabling the energy-saving mode and using the TV normally.

Disable Power Saving Mode

If the flickering reduces after disabling the setting, it could mean the TV was not drawing enough electricity to function correctly.

12. Troubleshoot Possible Internal Hardware Issues

If you’ve disabled power saving mode and are still experiencing consistent flickering, it’s possible that an electrical unit inside your TV, such as the ribbons, is wearing out.

Fixing internal problems on your own may not be possible unless you’re an expert, so it’s advisable to contact a professional to repair your TV or even consider purchasing a new one. If your TV is relatively new, it may still be under warranty. It’s worth a shot.

13. Seek Professional Assistance if Necessary

If none of the previous solutions have resolved the flickering problem on your TV, it’s advisable to seek the help of an authorized expert to take a closer look.

This is particularly important for newer TVs with more complex components.

In many cases, these components are soldered to the mainboard, which requires expertise and specialized tools to replace the damaged parts with new ones. Therefore, it’s best to seek professional assistance to ensure that the issue is fixed properly.
