You’re in the middle of watching the big game, and suddenly your TV powers off. This can be annoying but also embarrassing if your top-rated TV randomly powers down around guests. If your TV is regularly powering down on its own, you may wonder, “why does my TV turn off by itself?” Don’t fret because, in this article, we’ll tell you why your TV might randomly power down and how to fix it possibly.

KEY TAKEAWAYS:

  • A TV usually turns off by itself because of an unexpected signal from another device.
  • Most fixes are simple and only require the TV’s remote control.
  • In extreme cases, the TV’s motherboard is the cause of inconsistent power.

Why is My TV Shutting Off on Its Own?

TVs have become more and more complex over time, but some issues remain. For example, a TV that powers off randomly is a problem that has haunted many television owners. That said, there are only so many possible causes of unplanned TV shutdowns. Here, we’ll go through how to check why TVs turn off randomly.

Power Supply Problems

Check your power cord on both ends and make sure the TV and the wall connections are secure. A loose connection could cause spotty power. In turn you could experience display issues and keep wondering, ‘why is my tv black and white?’.

In addition, verify that your TV’s power cord is in good condition. A frayed or damaged power cord is a fire hazard and could struggle to supply your TV with energy.

Change Surge Protectors

If your TV is plugged into a surge protector, you may want to make sure it isn’t to blame for your TV turning off on its own. Instead, try plugging your TV into a different surge protector or directly into the wall outlet. Then, if your TV’s power troubles stop, you know your surge protector was to blame.

Test Your Remote

Sometimes, a damaged remote control can send out an errant signal to your TV and cause it to power down. On the other hand, if your remote is in good shape, the batteries might be to blame. Some remotes send random signals when low on battery power, so try changing out your batteries to ensure your remote maintains accurate performance.

Check HDMI-CEC Settings

HDMI-CEC or Consumer Electronics Control is a feature that lets devices affect each other over HDMI. For instance, if you turn on your Xbox One, CEC can automatically turn on your television and change to the suitable input. While CEC is very helpful, it can misfire and cause your TV to turn on and off at unexpected times. Go to your settings and turn HDMI-CEC off. Then, if your power issues resolve, you know what the cause was.

Disconnect From Smart Home Devices

Having a smart home full of connected devices is a tremendous 21st-century experience. That said, when services like Alexa or Google Home glitch, they can cause havoc with smart TVs. First, interrupt your TV’s connection to the intelligent service by turning off Wi-Fi in the menu. Now, you can see if your TV screen stays on when it should.

Check The Device Power Setting

Go into your device settings and find the power save setting. Most modern TVs have sleep timers that can range from 30 minutes to four hours. Make sure this setting is either turned off or set to a reasonable amount of watch time. This is a good option for people who want to be more energy-efficient, but it can disrupt a good time.
