Begin by inspecting the power source and the wiring system. A fluctuating power supply or improperly connected or faulty cables might lead to the TV turning off and on unexpectedly. Confirm that the electrical outlet operates properly and that the power cord is securely connected. Also, ensure that all additional cables, like HDMI and audio cables, are firmly fixed.

How To Prevent Your Hisense TV From Shutting Off?

If you’re frustrated with your Hisense TV turning off on its own, don’t worry, there are a few things you can try to fix the issue. Here are some potential solutions to get your TV working properly again:

Check your sleep timer settings: Your Hisense TV may have a sleep timer set, which can automatically turn off the TV after a certain period of time. Check your TV’s settings and disable the sleep timer if it’s on.
Disable CEC settings: Consumer Electronics Control (CEC) is a feature that allows you to control multiple devices with one remote. However, it can sometimes cause issues with devices turning off unexpectedly. Try disabling CEC settings in your TV’s settings menu.
Power cycle the TV: Power cycling involves unplugging the TV from the power outlet, waiting for a few minutes, and plugging it back in. This can sometimes reset the TV and fix any issues it may be experiencing.
Update your TV’s software: Check if there is a software update available for your Hisense TV. Updating the software can often fix bugs and glitches that may be causing the TV to turn off.
Check for overheating: If your Hisense TV is overheating, it may be turning off to prevent damage. Make sure the TV has proper ventilation and isn’t placed in a hot or enclosed space.

Restart The Hisense TV

Restarting a broken TV, regardless of the manufacturer, is one of the simplest ways to fix it.

Any problems with the television may be resolved with a simple restart, which will not take long.

Follow this procedure to restart your Hisense TV:

Point the remote at the TV and press the Power button.
Allow at least 30 seconds before pressing the Power button again.
After restarting the TV, wait a few moments to check whether it switches off again.

Perform A Power Cycle On Your Hisense Smart TV

Because energy never stops flowing through the components when you resume with the remote, it has no influence on the hardware.

Most hardware failures may demand a power cycle, which involves turning off and then turning back on all power to the TV.

Follow these procedures to restart your television:

Switch off the television.
Remove the television from the wall socket.
Wait at least 30-45 seconds before reconnecting the TV.
Start the television again.
Check to see if the TV turns on after being turned off.

Check Your Cables

Faulty or damaged HDMI or power cords may cause the TV to lose signal or shut down at random.

Hisense TVs also contain HDMI-CEC, thus if there is a problem with the HDMI cable, it may believe it is being instructed to turn off and do so.

Examine all of your wires for physical damage and clean any debris or dust from the end connectors.

Test the HDMI cable with another monitor to check that it is not the source of the problem.

Because the problem isn’t restricted to the TV, replace any damaged or frayed power or HDMI cables as soon as you notice them. It is also possible that it will start a fire.

I would recommend a Belkin HDMI 2.1 cable and a PWR+ power cord as appropriate replacements for your older cables.

Try Another Power Outlet

Power supply problems might arise not just from the TV, but also from a power socket that cannot give adequate power to the TV.

This causes the television to turn off at random intervals with no warning and has the potential to irreversibly damage your television.

By just plugging the TV into another socket, the likelihood that it is the power outlet is eliminated.

Unless your house isn’t getting enough electricity, if you try another outlet, your TV should stop acting up.

If the situation remains the same and the television continues to turn off, the socket may not be the culprit.

Turn off the energy-saving option on your Hisense TV

The energy-saving mode on the Hisense TV can be harsh at times, and it can turn the TV off at random when it deems it is not being used.

Turn this option off and check whether the TV turns off again.

To disable the capability, perform the following steps:

Start the TV’s menu.
Select the Settings option.
Select Energy Saving.
Adjust the setting to get the highest energy savings without allowing the TV to save too much power.
When you turn off the Energy-saving option, see if the TV turns off.
