How to Fix a Roku TV Flickering Screen


Why does my Roku TV Screen keep Flickering?

The main reason why your Roku TV screen keeps flickering is because the TV is receiving magnetic interference, the resolution settings are too high, or because the LED backlight panel is faulty.

 

Probable Causes:

  • Magnetic interference.
  • The resolution settings are too high.
  • There is a glitch.
  • Your TV’s backlight panel is faulty.

 

Magnetic Interference

If your TV receives magnetic interference from its surroundings i.e., from a nearby speaker or magnetic device, it can cause your screen to flicker. This is because magnetic interferences change the path of electrons causing the visuals on your screen to appear distorted.

 

The resolution settings are too high

Sometimes, if your TV’s resolution settings are set too high, it may put extra load on your TV. This can cause your screen to flicker – it is your TV constantly trying to match the picture quality you’ve set in the settings but failing to bear the load.

 

There is a glitch

Sometimes, there’s nothing more to a flickering screen than a random glitch. In such cases, all you can do is restart your TV.

 

Damaged backlight panel

Your TV’s screen panel or backlight panel produces the images you see on screen. If that (or related) internal hardware is damaged, your TV’s screen will flicker and fail to display anything on screen.

How do I fix my Roku TV’s screen that keeps flickering?

To fix your Roku TV’s flickering screen problem, either keep your TV away from any magnetic device, lower down its resolution settings, soft reset your TV, or call Roku’s customer support.

 

Magnetic Interference

If your screen is flickering because there is magnetic interference nearby, do a quick assessment of every electronic device that surrounds your TV. If they’re magnetic devices, place them far from your TV. This is especially important in the case of speakers- they’re the culprit behind such problems most of the time.

 

High resolution/ frame rate settings

Here are the steps you need to follow to resolve this issue:

 

  1. Go to settings and click system settings
  2. Click advanced system settings
  3. Click advanced display settings
  4. Find “Auto-adjust display fresh rate
  5. Click Disable
  6. If it is Disabled already, click enable and then Disable again
  7. Find the picture quality settings and choose a lighter option

 

Glitch

When your TV’s screen flickers due to a glitch, soft reset it.

 

Here are the steps:

  1. Use the remote to switch off your Roku TV.
  2. Unplug the power cord from the socket.
  3. Press and hold your TV’s power button for at least 30 seconds.
  4. This drains out any remaining power from within your Roku TV.
  5. Let go of the power button and let your TV remain switched off for 15 minutes.
  6. Lastly, plug your TV’s power cord back in and turn it on.

 

Damaged Screen Panel

Unfortunately, many at times, when you find your TV unable to show anything on display (except a flickering screen), it means that your TV’s backlight panel is faulty. Your TV’s backlight (screen panel) is responsible for the visuals you see on display.

 

Naturally, if this hardware deteriorates, your TV’s screen will only flicker. In such cases, all you can (and should) do is call Roku’s customer support for repairs/ replacement. Whatever you do, do not try to fix this issue on your own- there is a high chance you will damage other hardware in the process.

Why is my Roku TV Flickering on and off?
