Smart TVs have become a central part of home entertainment, and Hisense is one of the top choices for many households because of its balance of price and features. Still, a common issue that frustrates some users is the TV shutting off by itself. Few things are more annoying than settling in for a movie or game night only to have the screen suddenly go dark.
If your Hisense TV keeps turning off, there’s no need to panic. In most cases, the problem comes down to basic settings, power supply issues, or a minor software glitch. This guide will explain the main reasons why this happens, show you practical ways to fix it step by step, and share useful tips to stop the issue from coming back.
Why Does My Hisense TV Keep Turning Off?
Before trying to fix the problem, it helps to know what usually causes it. In most cases, the reasons fall into these groups:
- Power Supply Problems – Loose cables, faulty outlets, or a bad power strip can cut off power to your TV.
- Sleep Timer or Eco Mode – Many Hisense TVs include power-saving settings that switch the TV off after a set period.
- Overheating – If the TV’s internal parts get too hot, it may shut down automatically to prevent damage.
- Software Bugs – Outdated firmware can lead to crashes or sudden shutdowns.
- HDMI-CEC Conflicts – Devices connected through HDMI, such as consoles or soundbars, can sometimes send signals that turn off the TV.
- Hardware Faults – Though less common, issues like a damaged main board or capacitor can also cause the TV to power off.
The good news is that most of these problems can be fixed at home without needing a technician.

Method 1: Check the Power Source
One of the most common reasons a Hisense TV turns off on its own is an unstable power supply.
- Start by plugging the TV directly into a wall outlet instead of using a power strip. This helps ensure it’s getting steady electricity.
- Next, test the same outlet with another device to make sure the outlet itself isn’t faulty. If the other device also struggles, the problem may be with the power source.
- If you have a spare cable that works with your Hisense TV, try swapping it in. A damaged or loose cable can also cause the TV to shut down unexpectedly.
If the TV works fine after changing the outlet or cable, you’ve likely found the cause of the issue.
Method 2: Disable Sleep Timer
Many Hisense TVs come with a built-in sleep timer. This feature is useful if you like the TV to shut down automatically after a set time, but it can be frustrating if it switches off when you don’t want it to.
To check or disable the sleep timer, follow these steps:
Pick up your remote and press the Menu button.
- Navigate to Settings and select System.
Open the Timers option.
Look for Sleep Timer and see if it’s turned on.
If it is, change the setting to Off.
Once you’ve done this, your TV should stay on until you decide to turn it off manually.
Method 3: Turn Off Eco Mode / Energy Saving Mode
Some TVs come with energy-saving settings that help reduce power use. The downside is that they can sometimes make the TV turn off earlier than you want.
- To fix this, open the menu on your TV and go to Settings > Picture > Energy Saving Mode.
- Change the option to Off.
This way, the TV will stay on while you’re watching and won’t shut down automatically.
Method 4: Inspect HDMI-CEC Settings
If you’re using several devices with your TV such as a Roku, Firestick, PlayStation, or a soundbar HDMI-CEC could be the reason your TV keeps turning off.
- To fix this, open your TV’s menu and go to Settings > System > HDMI & CEC.
- Turn off HDMI-CEC to prevent external devices from controlling your TV’s power.
Method 5: Update the Firmware
Hisense often releases firmware updates to fix system issues. If your TV’s software is outdated, it may shut down on its own.
- First, make sure your TV is connected to Wi-Fi.
- Then, open Settings > Support > Software Update.
- Choose Check for Updates and install any available version.
After the update finishes, restart your TV and check if the shutdown issue is resolved.
Method 6: Prevent Overheating
Like most electronic devices, Hisense TVs may turn off if they get too hot. Overheating often happens when the TV doesn’t have enough ventilation or when dust blocks the air vents.
- To prevent this, make sure your TV is in a spot where air can move around it freely.
- Avoid placing it near heaters or in direct sunlight, as that can quickly raise the temperature.
- It’s also a good idea to clean the vents regularly.
- Use a soft brush or a vacuum with a small nozzle to remove any dust that may have built up.
If overheating was the reason your TV kept shutting down, these steps should help it run longer without turning off unexpectedly.
Method 7: Factory Reset the TV
If nothing else works, you can try a factory reset to clear hidden errors or damaged settings.
- Go to Settings > Device Preferences > Reset.
- Choose Factory Data Reset.
- Confirm your choice and wait for the TV to restart.
Keep in mind, this step will erase all apps, accounts, and personal settings. Use it only when other fixes have not solved the problem.
Method 8: Check External Devices
Sometimes the problem isn’t with the TV itself but with the devices connected to it. A faulty console, streaming stick, or soundbar can cause the TV to shut down.
- Start by disconnecting all HDMI devices.
- Turn on the TV with nothing else attached.
- Then reconnect each device one at a time to find out which one is causing the shutdown.
Method 9: Inspect the Remote Control
Sometimes the issue is as simple as the power button on the remote. If the button is stuck or not working properly, it can make the TV turn off on its own.
- To check, remove the batteries from the remote and see if the problem goes away.
- If it does, replace the old batteries with new ones.
- If the problem continues, try using the power button on the TV itself instead of the remote.

Method 10: Seek Professional Repair
If none of these methods fix the problem, your TV may have a more serious hardware issue, such as a faulty capacitor or motherboard. In that situation, you should:
Get in touch with Hisense customer support for further help.
Check whether your TV is still covered by warranty.
Visit an authorized repair center to have the device inspected and repaired.
Pro Tips to Avoid Future Shutdowns
Taking care of your TV isn’t complicated, but a few simple habits can make it last longer and work better.
- First, always keep your TV updated with the latest firmware. Updates often fix bugs and improve performance, so don’t ignore those notifications.
- It’s also a good idea to use a surge protector. This keeps the power supply steady and protects your TV from sudden spikes in electricity that could damage it.
- Try not to leave your TV on for more than 12 hours straight. Giving it short breaks helps prevent overheating and reduces wear on the internal parts.
- Where you place your TV matters too. Keep it in a cool spot with enough ventilation so air can circulate. Heat buildup is one of the main reasons electronics fail early.
- Finally, check your remote and timer settings from time to time. Sometimes, scheduled timers or stuck buttons can make the TV turn on or off unexpectedly.
By following these small steps, you’ll keep your TV running smoothly and avoid unnecessary problems.

Q: Why does my Hisense TV keep turning off after a few minutes?
A: If your Hisense TV shuts down on its own after a few minutes, there are a few common causes. The most likely reason is that the sleep timer is turned on, which tells the TV to power off automatically after a set time. You can fix this by going into the settings menu and turning the timer off.
