When you invest in something as regularly used and as costly as a TV, you expect it to perform without error. However, technology fails at times and TCL TVs are no exception.

One of the most fundamental and essential elements of any TCL TV is its ability to turn off and on. If you go to turn on your TV and find that nothing is registering besides a blank, black screen, there obviously is a problem. Even more, if you get your TV to turn on but it will not turn back off, you are left with a perpetual working picture during all those times when watching TV simply is not necessary.

If your TCL TV won’t turn on or off, first check to make sure that the TV itself is not the issue. To do this, go to the back or bottom of your TCL television and find the manual power button and try powering on your TV through this workaround. If your TV powers on, then the problem likely lies within your remote control, however, if it does not power on, then more investigation will be needed.

If you try to turn your TV on by its power button, check to see if the power cord is properly plugged into the TV and to the outlet. If this is not the issue, then a power cycle of the TV might be needed to get your TCL TV to turn off and on properly. To complete a power cycle, unplug the TV from its power source for 60 seconds then plug the TV back into that same power source to help things reset and restore back to normal.

TCL TV Keeps Turning On/Off By Itself

Next to your TCL TV not turning on or off at all, comes the problem of your TV turning on and off by itself. This may seem great for those of you who want a touch-free experience, but when you are in the middle of an overtime game, at the very end of your favorite movie, or are streaming the season finale of a new show, this can be a major problem. If you find that your TV randomly is turning off and on by itself, continue reading to find your solution.

If your TCL TV keeps turning off and on by itself, go to either the side or bottom of your TV and look for the reset button. When you find the recess of the reset button, take a long pointed object and press it into this recess while holding it for at least 15 seconds. Once you have held it in for those 15 seconds, remove the object. This should cause a factory reset for your TV causing the problem to stop.

There could be several other reasons behind a TCL TV turning on and off by itself, ranging from technical glitches to hardware problems. Here are some steps you can take to troubleshoot and potentially fix the problem:

  1. Check the Remote Control: Sometimes, an issue with the remote control can cause the TV to turn on and off unexpectedly. Make sure there are no stuck buttons or issues with the remote’s batteries. Try removing the batteries from the remote and see if the issue persists.
  2. Power Source and Cables: Ensure that the power cord and other cables connecting your TV are properly plugged in and not damaged. A loose connection or a faulty cable could cause intermittent power issues.
  3. Software/Firmware Update: Sometimes, software glitches can cause such problems. Check if there is a software or firmware update available for your TCL TV. Updating the software might resolve any bugs causing the issue.
  4. Factory Reset: Performing a factory reset on your TV can sometimes fix erratic behavior. Be aware that this will erase all your settings and preferences, so you’ll need to set up the TV again from scratch.
  5. Check for Timers: Some TVs have built-in timers that can turn the TV on and off at specific times. Make sure there are no unintentional timers set in the TV’s settings.
  6. Remove External Devices: If you have external devices connected (such as gaming consoles, Blu-ray players, etc.), disconnect them and see if the issue persists. Faulty devices or HDMI cables can sometimes cause issues.
  7. Environmental Factors: Extreme temperatures or fluctuations in the environment where the TV is located could impact its performance. Ensure the TV is in a cool, dry place.
  8. Electrical Issues: If none of the above steps work, it’s possible that there could be electrical issues with your TV or the power source. In such cases, it’s best to contact TCL’s customer support or a professional technician for assistance.
  9. Hardware Problems: If none of the above solutions work, there could be a hardware problem with the TV’s internal components. This might require professional repair or replacement of faulty parts.
  10. Warranty: If your TCL TV is still under warranty, it’s advisable to reach out to TCL’s customer support for assistance. Attempting to fix the issue yourself could void the warranty.

Remember, if you’re not comfortable performing these troubleshooting steps yourself, it’s always best to seek professional help to avoid causing further damage to the TV.

Beyond simply just turning off and on by itself, some TCL owners have experienced problems with their TVs restarting or rebooting continuously.

If you find that your TCL TV is restarting and rebooting more than it should, there are a few different solutions you can try below.

If your TCL TV keeps restarting or rebooting, check to see what might be causing the problem. If your TV is restarting each time you try to use a specific application, the application could be the problem rather than the TV itself. Uninstall the application and then run another application to see if the problem is solved, then you can reinstall that same application or update it as needed.

If a specific application is not the problem, it could be that your TV has not been updated with the most recent firmware. To update the firmware on your TCL TV hit ‘Home’ on your remote control > select ‘Settings’ > ‘System’ > ‘System Update’ > ‘Check Now” to check for any updates that are available > proceed with the download if available.

TCL TV Won’t Turn On But Light is On

Typically, when people experience issues with their TV turning on there is no sign of power whatsoever indicated from the TV. However, some owners of TCL TVs have reported and experienced issues with their TV not turning on, but a light is still operating on the TV, indicating that there is some sort of power. If you have a TCL TV that is not powering on, but has a light that is on, take a look below to troubleshoot your problem.

If your TCL TV won’t turn on but a light is on, make sure that your TV isn’t stuck on an input that is simply a black screen. This can be caused by other connected devices such as Blu-Ray players or even game consoles. To ensure that your TV is not simply stuck on a black screen, either press the home button which is located on your remote control or switch the inputs of your TV to change what is displayed.

If the black screen is still appearing and there is no sign of power, try completing a power cycle on your TCL, which will help to resolve any temporary system issues. The steps for this process can be found within the previous article “TCL TV Won’t Turn On/Off.” You can also attempt to reset the TV manually, which has previously been discussed in the same section, simply follow the instructions to complete a manual reset.

TCL TV Won’t Turn On No Light

If you go to turn your TCL TV on and a light appears on your TV, this is good because it is made clear that your TV is receiving power. However, if you try to turn the TV on, but no light is indicated, this can be cause for concern due to the lack of power that is being transferred to your TV. Although this can be rather alarming, no light on your TCL TV is not an indication that a major problem has occurred right off the bat.

If your TCL TV won’t turn on and there is no light, you first want to ensure that your TV is not only securely plugged directly into a power source, but that the same cord is also securely inserted into your TV. If you are using a power strip for your TV, this could also be the issue as some are not equipped to handle the amount of power that a TV expends. It is always wise to have your TV plugged into a direct power source.

When you verify that the power sources are either the problem or are not the problem, you will either stop here or continue on with more troubleshooting. If this does not resolve your issue, find the reset button on the back of your TCL TV and complete a manual reset which can be referenced in the previous section “TCL TV Won’t Turn On/Off.” You can also try plugging your TCL TV into a completely different power source to see if power is regained.

TCL TV Won’t Stay On

When you start your TCL TV and there are no issues with powering on, you may be inclined to think that all issues are far behind you. However, some owners have voiced problems with their TV turning off once it has turned on, therefore bringing about the issue of the TV not staying on. This is certainly a huge inconvenience for those trying to binge-watch a series or simply get through the news without interruption, so what can you do?

If your TCL TV won’t stay on, this problem could be caused by an internal timer that has been set within your TV. To check to see if any timers have been set, press the ‘Home’ button located on your remote control > scroll to ‘Settings’ > select ‘System’ > ‘Time’ > ‘Sleep Timer’ > and then check to see if any timers have been set to cause your TV to turn off automatically. If so, disable those timers.

If there are no timers set for your TV, check to see if any other devices may be conflicting with the TV itself, which may cause it to turn off on its own. For some, when using things like a Fire Stick that requires another remote to function, the signals can conflict which can cause the TV to power down. Remove the batteries from the spare remote and see if this stops the problem of your TV turning off on its own.
