Is your Hisense Roku smart TV turning on and off by itself? This article will explain how to fix the problem and prevent it from restarting or shutting off.
Why Is My Hisense Roku TV Turning On and Off By Itself?
Some of the more common issues, which are fixable, include power problems, a short sleep timer, or interference from other devices. Here are those issues described in more detail:
- If you have multiple Hisense Roku TVs in your home, the other remotes may interfere. For example, someone pressing the power button in a nearby room may be turning the TV on or off.
- Hisense Roku TVs can be turned on and off by other devices in your home, such as cable boxes, media players, and game consoles. To stop this, you can disable CEC mode on the device or on the TV itself.
- All modern TVs, including Hisense Rokus, have a sleep timer to power off the TV after a set period. You can check the time limit, disable the timer, or disable it entirely in the TV settings.
- A loose power plug, failing power strip, or surge protector may be causing power issues. Check the power plug at the outlet or adapter to ensure it’s properly connected.
- Most Hisense Roku TVs support either Chromecast or Miracast, which allows devices on the network to cast content to the TV. It may or may not be interfering with the signal.
Important: You cannot fix it yourself if something is wrong with Hisense Roku’s power supply on the actual TV set. You will need to have it serviced by a professional.
How to Fix a Hisense Roku TV That Keeps Restarting
If the TV does not stay on, you’ll need to do some troubleshooting to identify the problem. Here’s how to figure out what’s wrong with your Hisense Roku smart TV:
Tip: You can open Hisense Roku TV settings by pressing the Home button on the remote.
1. Check the power plug and outlet. If it’s plugged into a power strip or surge protector, check there instead. Make sure the plug is securely connected, not loose or askew. If it’s plugged in correctly, you might also consider checking your power breaker. Try plugging it into the wall outlet directly, if it’s not already.
2. Check the TV remote. The power button may be stuck. Also, remove extra remotes from the equation, especially other Hisense or Roku brand remotes.
3. Ensure no other devices nearby are powered on or interfering with the TV, including additional Roku remotes. If you believe another device may be affecting your TV, you can disable CEC.
Press the Home button on the remote control. Select Settings > System > Control other devices (CEC) and press OK to enter. Uncheck the One-touch play/System standby option.
Note: CEC only applies to device connected to an HDMI input on the TV.
4. Ensure no devices on your network are casting to the Hisense Roku TV, including mobile devices, computers, and tablets. If you believe this may be a problem, you can disable casting to a TV that’s powered off by navigating to Settings > System > Power and turning on Auto Power.
Note: Power saving mode ensures the TV is powered on before casting is available. Most newer models will have this option, but some older ones do not.
5. Enabling Fast TV mode may help when Energy Saver mode does not. To turn it on, navigate to Settings > System > Power > Fast TV start mode.
6. Review the Sleep Timer setting in Settings > System > Time > Sleep Timer. Either turn it off or change it to a later time. Sleep Timer will turn off the TV after a period of inactivity, but if the time limit is low, that may explain why the TV is powering down unexpectedly.
7. Reset the TV to factory settings. To do this, press the Home button on your Roku remote. Select Settings > System > Advanced system settings > Factory reset > Factory reset everything and follow the on-screen instructions.
8. Check for firmware updates via Settings > System > System Update > Check Now > Update now. If a firmware update is found, download and install it. Allow the TV to finish the operation and reboot. Then check to see if the problem resolves.
