Hisense TV Turning on by Itself

Let me clear one thing right away, if your Hisense TV is turning on by itself, your house is not Haunted!

It’s been well known that Hisense TVs have a habit of powering up unexpectedly. There are a number of known issues and complicated factors that may lead to this behavior of your Hisense TV.

Why is my Hisense TV turning on by itself?

There might be many issues causing your Hisense TV to power on by itself.

  • The most probable cause can be your TV’s HDMI-CEC function is turned ON!
  • Your TV Remote might have malfunctioned!
  • There might be a bug in your Hisense TV’s operating system, and you need to update it.
  • The power connection to the Hisense TV might be poor.

So, with that said, let’s discuss how to fix it in detail.

How to STOP Hisense TV from turning on by itself?

The auto-turning ON of your Hisense TV might have numerous causes; as I explained before, thus there are several ways to fix it.

1. Disable HDMI-CEC

Disable HDMI-CEC - Hisense TV

HDMI-CEC allows different devices, like a TV and a Soundbar, to talk to each other and share information.

For example, if you use HDMI CEC, you can use your TV remote to control your Soundbar. You can turn it on and off, change the volume, and even mute just by pressing buttons on your TV remote.

You may use a single remote to operate multiple HDMI devices with HDMI-CEC. Casting to a CEC-enabled TV will cause the TV’s source input to switch to the HDMI port where the casting dongle is attached, even whether you’re watching a local TV channel, using a cable, or plugging in a USB device.

So, when you turn on your PlayStation, your TV will automatically turn on and switch to the PlayStation HDMI port because of its HDMI CEC feature.

Most of the Smart TVs, including your Hisense TV, comes with this HDMI-CEC feature enabled because of the advancement of Smart Home technologies. Because your Hisense TV is turning ON by itself, this needs to be investigated.

Follow these steps:

  1. Turn ON your TV and go to Settings.
  2. Go to System
  3. Go to HDMI & CEC.
  4. Disable the CEC Control from there.
Switch off the CEC control and Device power on

And while we are here, let’s ensure that “TV Auto Power ON” is disabled.

  1. While in the HDMI & CEC settings, you can also find “Device Auto Power ON” to be enabled; just disable it as well!

Now the HDMI-CEC and auto powering ON functions are also disabled; you will have to manually turn on your TV and manually change your HDMI input source for external devices like PlayStation or Chromecast.

Besides that, you will not be able to use the remotes of other devices to control your TV.

Hopefully, your Hisense TV won’t turn on automatically again, but if it does, follow the other methods listed below.

2. Turn OFF any Active Timers

Hisense televisions are no different from other brands in that they include a selection of timer options, including Power-on timers, which turn your TV on at a particular time.

Ensure that such timers are turned OFF. To do that, follow these steps:

Set the "Sleep Timer" as "OFF"
  1. Turn ON your TV and press the Home button on your remote control to go to them the main menu.
  2. Turn ON your TV and go to Settings.
  3. Go to System.
  4. Go to Timer Settings.
  5. Finally, set the “On Time” as “OFF.”

While you are there, ensure that the Sleep Timer and any other timers you may have configured are turned OFF.

3. Power Cycle your Hisense TV

Power cycling is one of the mother solutions to most electronic device issues we face today. Though it may not sound significant, it is one of the best solutions.

  1. Turn OFF your TV.
  2. Unplug it from the Power Socket.
  3. Now, the trick is to wait 60 seconds before plugging it back in. (Do yourself a favor and wait at least a minute before reconnecting it.)
  4. Find the power button on your Hisense TV (NOT ON REMOTE) when it is unplugged and hold it down for 30 seconds.
  5. Finally, after doing it all, plug the power cable of the TV back into the socket.

The 60 seconds of no-power to the TV will assist in discharging the TV’s battery and enable a soft reset. That’s different than turning the TV ON and OFF via remote control.

4. Power Cycle Your TV Remote

If your TV still has issues after being unplugged and replugged in, consider power cycling the remote.

Follow these steps:

  1. Open the back cover of your remote control.
  2. Take out both of the batteries.
  3. While the batteries are out of the remote control, hold the power button on the remote, this time for 30 seconds.
  4. After 30 seconds, put the batteries back inside the remote control.

You have completely done a soft reset on the remote control; if it was malfunctioned, it should have been fixed.

5. Update the Operating System of your Hisense TV

If the operating system on your Hisense TV is out of date, it might experience a number of issues. The easy solution is to update the OS for your Hisense TV.

Although the OS updates itself, if the auto-update is turned OFF, you will have to update the operating system for your Hisense TV manually. Follow these guidelines to update the OS:

  • Tun on your Hisense TV and ensure it is connected to the Internet.
  • Go to the Main menu.
  • Go to Settings.
  • Go to Device Preferences.
  • Select About.
  • Select System Update.
Hisense TV system update

Your TV will automatically search for the latest update and download and install it itself!

6. Factory Reset Your Hisense TV

If none of the solutions work until now, you can try factory resetting your Hisense TV.

Caution: Factory resetting, also known as hard resetting, will delete your personalized settings and all the apps you have installed on your TV, bringing it back to the factory default settings.

Follow these steps to factory reset your Hisense TV:

  • Go to the Main menu.
  • Go to Settings.
  • Select Device Preferences.
  • Select Reset.
  • Finally, Select Reset.
  • Your TV will restart with all the factory settings, and you will be required to go to the Initial setup screen and set up the TV again.

You can also factory reset your TV by pressing the reset button on the back of the TV. It is hidden inside a small hole, and you must insert a pin to access the button.

Insert a pin inside the hole, and once the button is pressed, you will hear a clicking sound. Hold the button for 20 seconds, and your TV will factory reset.

7. Contact Hisense Customer Care

If the issue still needs to be fixed even after doing a hard reset, you will have to reach out to Hisense Customer Care.

You can reach out to them at their helpline: 1-888-935-8880 from 9 AM – 9 PM EST on weekdays and 9 AM – 6 PM EST on weekends.

They might charge you to fix your TV if you are out of warranty, and if your TV is still in warranty, you will get it fixed for free.

Final Thoughts

To conclude, there are a number of issues that can cause your Hisense TV to turn on by itself. First, ensure that the HDMI-CEC is disabled, check for firmware updates, and lastly, power cycle your TV and remote to fix the issue.

Filing a warranty claim may be necessary if none of these suggestions help.
