Time spent troubleshooting means less time enjoying your TV. Learn how to address this common Hisense TV power issue and keep your TV on.
Hisense TV Turns off Automatically
When you have a Hisense Roku, Google TV, or Vidaa, you can enjoy the fantastic quality of its video and audio features.
With the advent of HDMI 2.1 ports, you will get increased performance and definition. However, this enjoyment can be interrupted by issues that cause the TV to keep turning off.
Let’s review why your Hisense TV keeps turning off automatically.
The TV’s Settings Cause your Hisense TV to Turn off
Hisense TVs have a power-saving mode and an auto-off feature that reduce their energy consumption. If these settings are on, the TV screen will shut off unexpectedly.
How to Adjust Your Hisense TV’s Settings
To stop your Hisense Roku TV from turning off due to the Auto-Off feature on your TV remote:
- Go to Settings
- Select System
- Go to Power and select Auto Power Off
- Choose the auto-off settings that suit your needs. The TV can turn off after 15 minutes of no signal on input or after 4 hours of overall TV inactivity.
For Hisense Google TVs, use the following process:
- Press the Settings button on the remote
- Navigate to System and Power Settings
- Choose Energy Saver and select Never under the listed time options
For Hisense Vidaa TVs, they are by default set in “Energy Saver” mode. To turn it off, go to:
- Open the Settings
- Go to System
- Then select Timer Settings
- Choose Power Off Timer and turn it off.
Additionally, while in the Timer Settings menu, you’ll want to change the Auto Sleep and Auto Standby with No Signal settings.
Once you adjust the Energy Saving settings, the TV will stop turning off by itself.
Adjusting the Sleep Timer Settings on Hisense TVs
To turn off the sleep timer for Roku TVs:
- Open Settings in the Quick Menu

- Select Sleep Timer
- Choose the Off option
Alternatively, on Google TVs, use the following steps:

There are Problems with the Power Supply or Remote
Problems with the TV power cables or power outlet will cause it to turn off by itself.
- Power surges from a storm
- Power and HDMI cables may be faulty
- The outlet is broken or not releasing enough power
- The remote button is jammed, or the battery is low
How to Fix Power Supply and Remote Issues
The faulty TV parts must be replaced or patched to fix these issues.
An outlet needs to be replaced if you plug different devices into it and none power on. You can also test your outlets using a voltmeter to ensure enough power is getting to the outlet.
If the outlet needs to be replaced, you can do it yourself or hire an electrician. If you need more confidence in doing repairs, contact a professional.
You will know the power cords and HDMI cable will need to be replaced when the protective outer covering or cord has obvious nicks and tears. If these abrasions become severe, the cord will break and stop working.
If the power button is jammed on the TV remote, you will have to replace the remote. You could also try unjamming the power button using a small tool like a toothpick to get it unstuck.
Your Hisense TV is Overheating
Power supply problems cause TVs to overheat. Your Hisense TV will shut off automatically when overheating to prevent further issues.
If a TV overheats, the parts inside can explode and cause it to catch fire.
How to Cool Down a Hisense TV
To fix and prevent your Hisense TV from overheating, you can:
- Keep the TV away from furniture, curtains, and direct heat sources
- Use a fan to keep the TV cool at all times
- Reduce the number of devices connected to the TV
- Replace the power supply
- Replace the capacitors for the TV
You can change the capacitors yourself, but help from a technician is recommended if you are not used to doing electrical repairs.
The Hisense TV warranty does not cover physical damage, so you must choose between these options.
An Issue with the System Memory or a Glitch
Your Hisense TV could turn off if there is a glitch in the system or a memory problem—a smart TV functions similarly to a small computer. If there is a problem with the internal files that prevents proper functioning, it will shut off.
There could also be a driver issue. TVs have drivers that control things like audio and graphics. When one or more is having issues, the TV can turn off.
How to Fix a Glitch on a Hisense TV
To fix glitches, the best things you can do are:
- Power cycle your Hisense TV
- Update your Hisense TV’s OS
