Insignia Fire TV Screen Flickering

Why Is My Insignia Fire TV Screen Flickering?

Your Insignia Fire TV screen will flicker due to incorrect picture resolutions, wrong refresh rate selection, problems with HDMI cables, pending software updates, or minor glitches that usually go after your TV’s power cycle.

Other major hardware problems like faulty LED backlights, damaged COF cables, and motherboard faults can also create screen dimming and flickering issues.

How To Fix Insignia TV Screen Flickering Issue

If your TV screen is dim and flickering, then follow these solutions step-by-step:

1. Check HDMI Cable

Believe it or not, the tiny connector you use to feed your TV all those beautiful visuals—the HDMI cable—might be the culprit behind your flickering screen.

First things first, make sure it’s properly plugged in. If everything seems fine at a glance, try giving it a little push to ensure it’s securely seated in the port.

Still no luck? Time to go a bit deeper.

Unplug the HDMI cable and inspect it for any visible damage. Look for rust, kinks, or fraying that could mess with the signal.

Replace it if you find any defects, even minor ones. I’ve personally faced this, and a simple cable swap worked like a charm!

If the cable looks good, the issue might be with the port itself. Try connecting to a different HDMI port on your TV or switch devices.

2. Change Picture Resolution

Here’s a fun fact: not all that flickers is a hardware issue! Sometimes, your Insignia TV is just as confused as you are because it’s being fed the wrong picture resolution.

Like forcing a square peg in a round hole, incompatible resolution settings can cause your TV screen to flicker.

Navigate to the settings menu, find the picture or display settings, and try a different resolution.

1080p @60Hz is the sweet spot for most TVs, but you might want to try a step lower or higher, depending on your model.

You’ll be surprised how often this resolves the issue. It’s like finding the right pair of shoes – when it fits, comfort follows!

3. Check For Software Updates

Did you know your TV has a brain? Well, sort of. It runs on software that occasionally needs updates, just like your smartphone or computer.

An outdated TV software can lead to a host of problems, including, you guessed it, screen flickering.

Go to the settings menu, find the ‘About’ or ‘System’ section, and check for updates. If there’s an update available, install it.

If software updates are installed in the background, they may temporarily throttle your TV performance and cause screen flickering issues.

So, wait for a few minutes until your TV is updated to the latest firmware. After finishing software updates, reboot your TV and see whether the flickering issue is resolved.

4. Power Cycle Your Insignia TV

“Have you tried turning it off and on again?” It’s almost a cliché at this point, but it’s repeated so often for one reason—it works!

Power cycling your TV can resolve a multitude of sins by clearing temporary configurations that may be causing the flicker.

Turn off your TV, unplug it from the power source, and give it a minute or two (press and hold the power button to drain all residual power from capacitors).

Then, plug it back in and power it on. This quick refresh acts like a mini spa for your TV’s internal system. Just like us, our devices occasionally need a break to get back into perfect shape!

5. Reset Your TV

If your Insignia Fire TV screen still flickers, it’s time to bring out the big guns—a factory reset. It’s the electronic equivalent of a deep therapeutic cleanse.

This step will revert all your settings to factory defaults and delete all third-party installed app data.

To reset your TV to factory defaults, go to Settings> navigate to System> then Restore Factory Defaults. Now, confirm your choice and the TV will do the rest.

Remember, post-reset, it’s like you’re meeting your TV for the first time, so you’ll need to set it up again.

6. Contact Insignia TV Support

Sometimes, the best course of action is to admit we need help. If you’ve tried all the above without success, it’s time to call in the experts.

Reach out to Insignia’s customer support. Their technicians can offer guidance, and if your TV is under warranty, they might repair or replace it if there’s a hardware issue.

Here’s details of Insignia TV customer support-

Potential Hardware Problems

As much as we’d like to solve everything with a few button clicks, some issues are rooted in the TV’s hardware. Problems with the TV backlights, a faulty motherboard, or a broken COF (Chip on Flex) cable require professional attention.

  • TV Backlights: If these lights fail, your screen may flicker or even go completely black. Replacing backlights is not a DIY job unless you’re an experienced technician.
  • Faulty Motherboard: The motherboard is the heart of your TV’s operations. Your TV screen might flicker or get vertical or horizontal lines if it doesn’t supply the necessary graphic processing voltages.
  • Broken COF Cable: These tiny cables are fragile and can cause display issues when damaged. Again, this is something a technician will need to handle.

Contact Insignia support or a local technician if you suspect any of these problems. Don’t open the TV yourself; it could void your warranty or cause further damage.


Dealing with a flickering TV screen can be frustrating, but you’re not alone. From checking cables to contacting support, we’ve explored practical steps to reclaim your viewing experience. If these solutions don’t do the trick, professional help is just a call away.
