Why Does My Insignia TV Keep Turning Off?

An Insignia TV can keep turning off for several reasons, such as:

  • Lack of power
  • HDMI cable is not secure
  • Old age
  • A software update is needed
  • External device interference

Let’s take an in depth look at the most common causes and solutions for an Insignia TV that keeps turning off.

1. Underpowered

Your circuit may be overloaded or unequipped to handle your Insignia TV if it keeps turning off. This can also happen if your power cable is loosely plugged into the wall. First, the “reset” button on your outlet to reset it.

Plug the Insignia TV into another outlet to see if there is a problem with the old outlet or with the power cable. Cord extenders can dilute a cable’s power, and you can increase a cable’s strength if you remove the extender. Use a longer power cord instead of an extender so that you don’t lose any power.

You may need to replace the outlet entirely if it is damaged but your other outlets work. It is possible to replace an outlet without professional help, but it is ideal to hire a professional.

2. HDMI Cable Loose in Port

A loose HDMI cable can make your Insignia TV turn off and on until you plug it in tightly. It is easy for a cable to come loose in the HDMI port, especially if it wasn’t plugged in completely from the start. You can try to use one of the other 2-3 HDMI ports if one of them is damaged and you cannot plug into it completely.

Replace the HDMI cable if it doesn’t fit into any of the ports. Generally, HDMI cables are a one-size-fits-all item, but faulty cables may not fit the port. You should be able to fix the problem if you push the HDMI cable into the HDMI port more tightly if your Insignia TV keeps turning off.

3. Older Model

Older models of TVs are more prone to problems, and old age is a major reason that your Insignia TV keeps turning off. Insignia TVs last for an average of 7 years, but they can last well over 10 years in some cases. However, you are more likely to experience errors with your Insignia TV if it is over 5 years old.

You can try to troubleshoot your TV and reset it, but it ultimately will continue to have problems until you replace it. With that said, an Insignia TV can often work well until the end if you take care of it and try not to use it too much.

4. Software Upgrade

An Insignia TV cannot work to its highest potential if the software is out of date. You typically need to update a smart TV’s software at least twice per year for it to run as intended. Insignia TVs can present a prompt telling you that there is an update, but you may need to select the update in the settings.

  • Go to ‘Menu.’
  • Then, select ‘Settings.’
  • Choose ‘System.’
  • Click ‘System Update.’
  • Select ‘Check Now.’

Turn on the “automatic updates” function in your settings so that you don’t have to worry about missing an update again. Automatic updates ensure that your Insignia TV will run smoothly and as intended by the brand. Outdated software can also affect the speed, performance, and even image on your Insignia TV.

5. External Device Interference

Your Insignia TV may turn off at random if it is in an area with too smart devices that use a wireless signal or plugged into a crowded outlet. Limit how many devices that use Wi-Fi you put in the same space as your Insignia TV. Unplug smart devices near your TV to see if it keeps turning off and improve the Wi-Fi signal strength.

If you have an older television, upgrade to a newer model with ‘Power Saving Mode’ and updated software capabilities. The more wires and wireless signals you have around your television, the greater the chance for interference. This is especially true if there is no insulation in the device itself.

Why Does My Insignia TV Keep Restarting?

Typically, Insignia TVs keep restarting as a result of a system malfunction or outdated software.

Updating the software takes between 5-15 minutes and can be prompted through the home menu. Follow the steps to update your television!

Your device should automatically reboot after installing any upgrades; if it does not, try holding the power button on your remote for 5 seconds. Sometimes, however, there may be an issue where there’s just simply not enough memory to support all of the features in the new update.

To address a system malfunction, perform a hard reset on your television.

Why Does My Insignia TV Keep Changing Input?

If your Insignia TV keeps changing input, it’s probably an issue with the remote control or HDMI cord.

Change the batteries on your remote (Insignia’s usually take two AAAs) first. Then, check out the HDMI cord for proper security on both the TV and outlet sides. Next, switch input sources on your TV and HDMI ports with your cord.

If this doesn’t take care of the problem, contact a certified Insignia technician to inspect your TV and diagnose the issue.

The Bottom Line

If your Insignia TV keeps turning off unexpectedly, there are a few things that are likely to blame.

An old TV, lack of sufficient power, or interruptions caused by other electronic devices could be the source of the problem. Additionally, your TV may not have enough storage space for the latest software update.

First and foremost, check the power cord and other cables for damage or loose connections. Next, try resetting the television by unplugging it from the electrical outlet and holding down the power button.

Lastly, if none of this works, contact Insignia customer service. They may be able to do a factory reset depending on what model your television is. Note that newer models come equipped with more features and software capabilities than older ones do.
