Hisense TV Turning On and Off [Here’s How to Fix It]

If your Hisense TV has been acting up lately, randomly turning itself on and off, you’re not alone. Many Hisense TV owners have experienced this frustrating issue. But don’t worry, there are several potential solutions to get your Hisense television working properly again. 

In this comprehensive guide, we’ll explore the reasons behind a Hisense unit powering on and off unexpectedly, and provide step-by-step troubleshooting methods to fix the TV issues.

Why Is My Hisense TV Turning Off After Powering On?

There could be several reasons why your Hisense television is cycling through on and off states. Let’s dive into some of the most common culprits behind these TV problems:

Power Supply Problems

A faulty power supply is often the root cause of a Hisense TV turning itself on and off. This could be due to issues with the following components:

Power Cable

The first thing to check is the power cable itself. Over time, cables can become damaged, frayed, or loose, leading to disruptions in the power supply. Take a close look at the cable and inspect it for any visible signs of wear and tear. If you notice any damage, try replacing the cable with a new one to see if that resolves the issue.

If the cable appears to be in good condition, try using a different cable to rule it out as the source of the problem. Sometimes, even if the cable looks fine, there may be internal damage that’s not visible to the naked eye.


Another potential issue could be the electrical outlet itself. To test this, try plugging in a different device, such as a lamp or charger, into the same outlet. If the other device works without any problems, it’s likely that the issue lies with the TV or its power cable.

However, if the other device also fails to work properly, it could be an indication that the outlet itself is faulty. In this case, you may need to have an electrician inspect the outlet or try plugging the TV into a different outlet.

Additionally, it’s always a good idea to use a surge protector or power strip with your TV. Voltage fluctuations or power surges can potentially damage the TV’s internal components, leading to issues like the one you’re experiencing. Using a surge protector can help regulate the power flow and protect your TV from potential damage.

Power Strips

Speaking of power strips, it’s important to note that these devices can also malfunction or degrade over time. If you’re using a power strip with your Hisense TV, try bypassing it and plugging the TV directly into the wall outlet. If the issue persists, it may be time to replace the power strip.

Compromised Mainboard

If you’ve tried all of the above steps and the problem still persists, it’s possible that the issue lies with the TV’s mainboard or motherboard. This is the central component that controls the TV’s various functions, including power management.

Unfortunately, if the mainboard is compromised, it may require professional repair or even a complete replacement. This can be a costly endeavor, so it’s important to weigh the cost of repair against the cost of purchasing a new TV.

Disable Your Sleep Timer

Before diving into more complex troubleshooting steps, it’s worth checking if the TV’s sleep timer is accidentally enabled. Many modern TVs come equipped with a sleep timer feature that automatically powers off the TV after a set amount of time.

If this feature is enabled, it could be causing the TV to turn off unexpectedly. To check this, navigate to your TV’s settings menu and locate the sleep timer option. Disable this feature and see if the issue is resolved.

Could Factory Resetting My Hisense TV Fix This?

Could Factory Resetting My Hisense TV Fix This

If the power issues persist after checking cables, connections, and the power supply, performing a factory reset can sometimes resolve the problem. A factory reset essentially restores the TV to its original settings, clearing any potential software glitches or configuration issues that may be causing the problem.

To factory reset your Hisense TV, follow these steps:

  1. Press the “Menu” button on your remote control.
  2. Navigate to the “System” or “Settings” menu.
  3. Look for an option labeled “Factory Reset” or “Reset to Default Settings.”
  4. Follow the on-screen prompts to complete the reset process.

It’s important to note that performing a factory reset will erase all of your personal settings and preferences, including any saved channels, picture adjustments, or other customizations. If possible, it’s a good idea to create a backup of your settings before performing the reset, so you can easily restore them afterwards.

After the reset is complete, you may need to go through the initial setup process again, but hopefully, your TV will be functioning properly without the power cycling issue.

Other potential fixes for a Hisense TV that keeps turning on and off:

  • Check for overheating issues and ensure proper ventilation around the TV.
  • Update to the latest TV firmware from the Hisense manufacturer. Software updates can sometimes address power-related bugs.
  • Try safe mode to disable any third-party apps or features that may be causing conflicts and leading to power issues.

When to Seek Professional Assistance

In some cases, you may need to seek professional assistance or repair service for your malfunctioning Hisense TV, particularly if:

  • There are clear signs of physical damage to the TV’s internal components.
  • None of the DIY troubleshooting solutions mentioned above have worked.
  • You’re not comfortable attempting more advanced repairs or replacements yourself.

Seeking professional repair service can be costly, but it may be necessary if the issue is related to a faulty mainboard or other internal components that require specialized knowledge and tools to repair or replace.

It’s important to weigh the cost of repair against the cost of purchasing a new TV, especially if your current TV is older or if the repair costs are significant.
