There’s no worse moment when watching your favorite TV show than having your device randomly turn off during a particularly exciting scene. If you don’t know what is causing your TV to turn off, the device can quickly go from being a source of entertainment to a major cause of frustration.
If you can’t seem to keep your TCL TV on, this article will help you find and fix the problem. Continue reading to learn what can cause your TCL TV to turn off and how to prevent this from happening.
Defective/loose power cable
Sometimes the simplest solution is the one that works. In the event that a TCL TV turns off, the problem could be due to the power cord not being plugged into the outlet properly. In fact, several causes can come into play here:
- Lost Connection
- A faulty power cord
- Malfunctioning power strip or UPS
- Power surges
- Defective wall socket
The best way to check if any of the factors listed are causing the problem would be to connect a different device (one that is working properly) to the power strip or outlet where your TV is connected. If the other device works, you can immediately eliminate any power connection problems. At that point, the next necessary step would be to check if your TV’s actual power cord is damaged.
On the other hand, if the different device also does not work properly in the power strip or outlet where the TV was plugged in, you can be pretty sure that one of them is defective.
Remote control problems
Another common and relatively simple solution is that the remote control does not work correctly. The problem, in this case, could be as simple as a stuck power button, which could be caused by dirt, small debris, or spills.
Before cleaning your remote control, you can confirm if this is the root of the problem by removing the batteries. If your TCL TV keeps turning off, then surely the remote control is the culprit. Also, while the batteries are dead, press and hold the power button, then press all other buttons on the remote control to reset the device. Replace the batteries to check if the problem is fixed.
Problems with HDMI CEC
TCL TVs have a special feature called HDMI CEC. This feature allows you to use a single remote control for all your connected devices. However, a known bug with HDMI CEC can cause the TV to turn off without your intervention.
The best way to confirm if HDMI CEC is causing the problem is to disable it and see how your TV reacts:
- Enter your TV’s “Settings” menu and go to “System.”
- Find the “Control other devices” option and enter it.
- Look for checked boxes and, if there are any, uncheck them.
- Restart your TCL TV.
Firmware failure
Like most software, your TCL TV’s firmware is not perfect. Sometimes, usually after prolonged use, the software can crash and cause the TV to turn off by itself. In that case, restarting the device could be the solution you are looking for.
To reset your TCL TV, you can go the basic route and simply unplug the power cord from the outlet. But the following method will provide a more detailed solution:
- Using your remote, navigate to “Settings” and then “System.”
- Using the right arrow, go to “Power.”
- Go right once more to get to “System Reset.”
- Press the right arrow once more to find the “Restart” option.
- Confirm and let the TV restart.
Sleep time
Going back to relatively simple solutions, it may be worth checking if the sleep timer is activated. Shutdown timers can be quite useful, but they’re also easy to forget about, resulting in some unexpected shutdowns.
Fortunately, turning off the sleep timer on your TCL TV is an easy task that is done in just a few steps:
- Go to “Settings” and then “System” on your TV.
- Look for the “Timers” p that contains sleep timer options.
- Enter the “Sleep Timer” menu and turn off the timer.
If the sleep timer was the cause of the problem in the first place, you will need to keep the TV on for a while to see if the problem resolves. On the other hand, if your TV turns off for a different reason, you probably won’t have to wait too long to find out.
Outdated software
Software updates aren’t just for minor tweaks to device systems. Instead, getting the latest version of your TV’s firmware can eliminate known bugs and improve security and functionality. If the TV turning off is not just a problem with your inpidual device but a relatively common problem, it will likely be fixed in the latest update.
In other words, updating your TV software is crucial. While updates can be done automatically, you may need to start the process manually in this case. How you install the update will depend on whether your TCL device is Android or Google TV.
Let’s start with the method for Android TVs:
- In the “Settings” menu, scroll down to “More Settings” and then to “Device Preferences.”
- Go to “System Update” and choose “Network Update.” The TV will check for new software versions online.
- If an update is available, confirm the action by tapping “OK.”
The process will be somewhat shorter on Google TV:
- Go to “Settings” and then “System.”
- Navigate to “About” and continue to “System Update”.
- Perform further steps according to the instructions on the screen.
Factory reset required
As long as no other method works, you will be left with another option before having to take your TCL TV to a repair shop. The option in question is the factory reset, which will revert all of your TV’s settings to their default values.
Accessing this option is easy: all you need to do is go to “Settings”, “System”, “Advanced system” and finally “Factory reset”. Please note that this method will delete all your data and apps, so make proper backups beforehand.
