Problems that cause the TV to repeatedly turn off can impede this enjoyment.

Why does my Hisense TV constantly turn off?
The following are a variety of reasons your TV may continually go off:
1. Active Energy Conservation Mode
The Hisense TV has an energy-saving design. This is a problem because the TV switches off while it’s playing content and then comes back on when it senses no signal is there.
When you connect items to the HDMI connector, your TV essentially loses power, frequently shutting off by itself.

In some circumstances, the Energy Saving Mode may have been chosen in a menu setting without your knowledge if your Hisense TV keeps shutting off.
The mode can be concealed from view if the TV is left on for a prolonged period, but it’s often available during normal operation.
2. Remove the HDMI cable

Any gadget that is plugged into your TV could potentially cause the device to shut off. In this situation, reconnect the HDMI cable and retest the problem.
The majority of issues ought to be resolved by now. If the problem persists, consider turning off your TV and all connected devices before turning them back on.
3. A damaged HDMI cable or socket
If you discover that you are experiencing several problems, your TV’s HDMI port is probably broken.
With your fingertips, check to see if the HDMI socket is loose. If so, your cable might not be correctly plugged in.
To see if the problem still exists, try disconnecting the cable and then turning on the TV once more. If it does, contact your TV’s support line for additional troubleshooting instructions.
An inherent security flaw is that remote controls of most smart TVs are designed to work in a benign environment rather than an adversarial one, and thus wireless communications between a smart TV and its remote controls are not strongly protected.
4. The Sleep Time Setting is active.
Your TV may abruptly turn off on its own if the sleep time setting is enabled.
Try switching the settings to a different choice if this is the case.
Changing your sleep time setting will also likely result in a reduction in your electricity usage.
5. A defective power supply

Your TV’s power supply could be broken and you could have a problem with the voltage output. See whether replacing it with a fresh one will fix the issue.
Another possibility for this issue is that your TV needs to be rebooted after operating in suspended animation for an excessive amount of time.
6. The TV Has Too Many Powers Fail/Extended Settings
If your TV has too many power fail settings, it will attempt them all at once and shut off in the process.
Your TV may automatically switch off if you have too many power extension settings open on it because of the increased demand for electricity.
7. Operating System that is out of date
Your TV’s operating system can be out-of-date and incompatible with the device’s hardware.
You can manually upgrade your operating system by downloading it from the internet if this is the case.
However, you must exercise caution while making updates to your TV because they may impact its performance.
