It can be frustrating when your TCL Roku TV keeps restarting while you’re trying to watch your favorite shows. A restarting Roku TV indicates an underlying issue that needs to be addressed. In this post, we’ll explore the top 7 reasons a Roku TV keeps restarting and how to fix them.
1. Overheating
One of the most common reasons for frequent Roku TV restarts is overheating. Modern flatscreen Roku TVs house a lot of electrical components in a slim body. If the ventilation is obstructed or the internal fans fail, the system can overheat.
An overheating Roku will automatically restart to try and cool itself down. Check to see if your Roku TV feels hot to the touch right before a restart occurs. Also ensure your TV has at least 2-4 inches of clearance on all sides and the ventilation holes are dust-free.
If overheating seems to be the culprit, improving ventilation should stop the random restarts. As a temporary fix, aim an external fan to blow cool air on the back of the overheating Roku TV.
2. Outdated Software
Roku periodically rolls out system software updates with bug fixes, security patches, and feature additions. If your TV’s software is severely outdated, it may trigger stability issues like random reboots and freezes.
Go to “Settings” and then “System” to check your Roku TV’s current software version. Then visit Roku’s website to see if there’s a newer update available to download. Keep your system updated to avoid software-related glitches.
3. Faulty Power Board
The internal power supply board provides stable power to run your Roku TV’s electronics. If this power delivery is interrupted, it can force the TV to suddenly restart.
A failing power supply board can struggle to deliver steady power as components wear out over years of heat/electrical stress. Inspect the board for burnt smell/discoloration and replace it if faulty. Check that all connections to the board are intact too.
4. Bad Power Source
Problems with your power outlet, surge protector, or cables can also make a Roku TV restart. Bad power sources deliver inconsistent electricity to the TV, triggering random reboots.
Ensure that the wall socket and any intermediate extensions/power strips are undamaged and fully functional first. Next, try using a different power cable in case the current one is faulty. Also rule out loose connections by wiggling the plugs and ports.
If the restarts decrease significantly after changing cables/outlets, it confirms the issue stemmed from a bad power source.
5. Wi-Fi Connectivity Problems
A Roku TV relies on internet connectivity for vital functionality. Loss of Wi-Fi signals can de-synchronize its processes and force a spontaneous restart.
Verify if other devices connected to the same network also face connection drops. Switching router channels and locations may help establish a reliable signal if range is the issue.
Also check if the restart only happens when streaming high-bandwidth video content. In that case, talk to your internet provider about bandwidth throttling or upgrades to resolve connectivity problems.
6. Faulty Remote
Roku remotes transmit signals via wireless connectivity too. A malfunctioning Roku remote can send erratic signals to disrupt the software, eventually causing system restarts.
Inspect your Roku remote thoroughly – replace batteries, check for physical damage, ensure proper pairing, etc. Try controlling the TV via the Roku mobile app instead. If restarts decrease significantly, your traditional IR remote was the likely culprit.
7. Bad Mainboard
Roku TV mainboards are responsible for overall system coordination. A failing mainboard can glitch out the delicate software-hardware balancing act, resulting in crashes and restarts.
Unfortunately, mainboard issues require professional diagnosis and repair. Contact Roku customer support so they can walk you through troubleshooting and potential mainboard replacement if needed.
Preventing Future Roku TV Restarts
Frequent, random Roku TV restarts are irritating and cut into your entertainment time. Thankfully, the thorough step-by-step troubleshooting guide above should help identify and resolve the restart triggers for good.
Once you’ve fixed the underlying issue, take proactive measures to prevent future Roku crashes. Keep the software updated, avoid overheating, use surge protectors, inspect components annually, etc. With proper use and maintenance, your Roku TV will deliver stable performance for years. I hope this TCL Roku TV keeps restarting post helped you.
