How to Fix Hisense TV Keeps Turning Off
If your Hisense TV turns off automatically every 5 seconds without any command, follow these troubleshooting steps to resolve the issue.
Restart your Hisense TV
Restarting your Smart TV can often fix any errors or temporary glitches causing the TV to turn off or malfunction. Follow these steps to restart your Hisense TV:

You can now test if this method has resolved the issue. If not, proceed to the next troubleshooting step.
Turn Off Energy Saving Mode
The Energy Saving feature on Hisense Smart TV helps conserve power by automatically turning off the TV when it’s idle for a certain period. This might be the reason your TV turns off automatically.
To fix this, disable the Energy Saving feature on Hisense TV through the settings menu. After turning off this feature, power on your TV and check if the issue is resolved.
Disable Sleep Timer on Hisense Smart TV
The Sleep Timer, similar to the power-saving mode, automatically turns off the TV after a set period. However, glitches might trigger this feature unexpectedly. To prevent this, it’s advisable to disable the Sleep Timer.

Update Your Hisense Smart TV
Outdated software on your Hisense TV can lead to technical difficulties. To prevent these issues, update your Hisense Smart TV to the latest firmware. The update process may vary depending on the model, so follow the on-screen prompts to manually update the firmware.
Note: The Hisense XClass TV updates its firmware automatically in the background when connected to WiFi.
Check Remote Control Buttons
Another aspect to consider is your Hisense TV remote. Problems with the remote can cause unintended commands, leading to the TV turning off unexpectedly. To address this, try resetting your Hisense remote control.
1. Remove the batteries for a minute, then reinsert them.
2. If the issue persists, replace the batteries.
Additionally, if the Power button on the remote is stuck, it might cause the TV to turn off. Inspect the remote buttons and fix any issues. Once this process is complete, turn on your TV and see if the problem is resolved. If the TV continues to turn off, proceed to the next troubleshooting method.
Inspect Power Supply
Your Smart TV may not function properly if there’s a power fluctuation or insufficient power supply. Before attempting any major fixes, check the power socket. Plug the TV’s power cable into a different socket to see if the issue persists. If the TV works fine with a different socket, consider replacing the faulty socket with the help of a technician.
Check Power Cables
A damaged power cable might be causing your Hisense TV to turn off unexpectedly. Inspect the TV’s power cable and HDMI cable for any signs of damage, such as bends or exposed wires. Ensure that all cables are in good condition and securely connected to the TV slots without any interference.
Reset your TV
If your Hisense TV’s storage is running out, it may have accumulated corrupted cache and bugs, leading to apps malfunctioning and the TV turning off automatically. To resolve this, you can perform a Factory Reset.
Resetting your Hisense Smart TV will remove any bugs and clear the entire storage, including app data. If you are comfortable with this, proceed with the factory reset.
If the previous troubleshooting steps didn’t resolve the issue, the problem might be with your TV’s internal hardware. In this case, contact Hisense’s technical support to inspect the physical components for any damage. If damage is found, consider replacing the affected parts. If your Hisense Smart TV is still under warranty, you may be eligible for free service.
