Why Is Hisense Roku TV Turning On & Off?
Hisense Roku TV turns on and off due to a loose power cable, a software glitch, hardware issues, connection problems, or remote control damage. You can identify which reason is causing the error by troubleshooting your device.
Roku or the TV manufacturers themselves have not provided any official explanation regarding the reason for this occurrence. However, according to unofficial sources, it seems linked to a driver update.
How to Fix a Hisense Roku TV That’s Flashing On & Off
These are the methods to fix Hisense Roku TV when it’s flashing on and off:
Method 1. Check the Power Outlet
If there’s a problem with the power outlet, it can lead to power fluctuations in your TV. The fluctuating power supply can cause your Hisense Roku TV to turn on and off unexpectedly.
Check the power outlet where you’re plugging your Hisense Roku TV. Examine any loose or damaged cables and see if your outlet is still working.
It’s also possible that the power outlet you’re plugging your TV into is defective and unable to supply sufficient power to the device. Disconnect the TV from its current power source, then plug it into a different outlet to determine if this resolves the issue.
Method 2. Check Your Remote
If you’re experiencing issues with your Hisense TV turning off unexpectedly, it could be due to the remote’s buttons getting stuck. Don’t worry, it’s a common problem.
To fix it, take a look at your remote. Make sure the buttons aren’t stuck or sticky. If they are, simply open your remote, clean its board and buttons with a damp cloth, and check if the problem is resolved.
Interference caused by the remote control’s signals can turn the Hisense TV on and off. To avoid this, you should ensure no obstructions between the remote and the TV. If required, replace the batteries of the remote.
Method 3. Check Connected Devices
If your HDMI or power cords are damaged or faulty, your Hisense TV may keep turning off. You should replace any damaged HDMI cords to avoid any potential issues. You can also plug and unplug any connected device to your TV to troubleshoot the issue.
Moreover, manually examine the inputs on your Hisense Roku TV by checking each HDMI or AV connection. Go to the “Input” menu and press the button beneath the Hisense logo on your TV. You can also navigate through the inputs by using the same button.
Method 4. Check if Your TV Is Overheating
Your television may shut off automatically as a protective measure if it overheats. Do not place your TV in an enclosed space to prevent this from happening. It’s also important to clean any dust or debris that may have accumulated in the vents to maintain proper airflow.
Your Hisense TV can overheat due to several factors, such as dust accumulation in the ventilation system or improper installation. Even a faulty component can cause overheating and ghost spots on your TV.
Method 5. Check if the “Sleep Timer” Is On
Check if your Hisense Roku TV’s sleep timer is on. This function automatically powers off the TV after a certain period of inactivity. If required, deactivate the sleep timer.
To check if the sleep timer is on, go to “Settings > System > Time > Sleep Timer”. If it says 30 minutes, 1 hour, or 1.5 hours, it means it’s on. Select “Off” to disable it.
According to Roku Support, you can use the sleep timer on your Roku TV to power off the screen after a designated time. The feature works whether you’re streaming content, watching live TV, or viewing an external device.

Can Hisense TV Be Repaired?
A Hisense TV can be repaired under warranty or for an average cost of 65 to 335 US dollars, depending on the problem. Sometimes, repairing a TV may not be feasible, and you may have to consider replacing it.
Your Hisense Roku TV might keep turning on and off if it has a problem with its display panel capacitor. To solve this issue, replacing the capacitors is necessary.
Replacing a defective capacitor in your display panel may seem complex for those without technical know-how. However, it is relatively straightforward. But you shouldn’t attempt to open your TV if a warranty still covers it.
A TV is irreparable if the screen is damaged, it fails to turn on even after multiple attempts, or if there is no sound output, it would be appropriate to begin searching for a new TV set.
Hisense allows you to extend the warranty if you need it. Check Hisense for more information.
