If the light on your TCL is blinking, it means there is power, which is always a good sign. However, if the light on your TV is blinking but it is not turning on, owners may be perplexed as to where the problem is originating.

There are a few different things that could be causing this problem, so try a few different troubleshooting methods before calling it quits and calling in the repairman.

If your TCL light is blinking and your TV is not turning on, try performing a power cycle, which will reset your TV and resolve any temporary issues it is experiencing. To finish a power cycle, unplug your TV from the power source and leave it for 60 seconds. After 60 seconds, plug the TV back in and try to turn it back on.

If this does not solve your problem and your TCL TV continues to blink with no power displayed, it is possible that the TV is actually turned on but is displaying a black screen.

Another connected device, such as a Blu-Ray player or game console, could be to blame. To change the screen, either press the home button on your remote control or change the input on your TV with the remote.


If you are not experiencing general issues, but rather have more specific issues with your TCL TV light that need to be addressed, there are solutions available. If your TCL TV continues to flash white, the light is attempting to communicate something very specific. For most TVs, this is a connectivity issue that can be resolved quickly.

If your TCL TV continues to flash white, this is usually a message indicating a problem connecting your TV to either your WiFi or wired internet source. To check your WiFi connection, use your remote to navigate to ‘Home’ > ‘Settings’ > ‘Network’ > ‘About’ > ‘Network Status’ > then check the ‘Internet Strength’ to ensure that it is either Excellent or Good.

If your signal strength is low, this could be the source of your issue, and your internet should be reconfigured. To test your connection with wired internet, follow the same steps, but at the end, ‘Internet Download Speed’ will appear, giving you either an Excellent, Good, or Poor connection.

You now know that a white flashing light on your TCL TV most likely indicates a connection problem. What does it mean when your screen continues to flash black?

This issue involves the actual picture going black while the TV is turned on, but instead of remaining on, the picture reappears. Although this is not as serious as the TV not turning on at all, it can be extremely inconvenient when you simply want to watch TV without interruption.

If your TCL TV continues to flash black, a power cycle may help to correct any minor glitches that have crept into your TV. To complete a power cycle, return to the previous section “TLC Light Blinking Won’t Turn On” and follow the steps to reset your TCL TV; if this does not resolve your problem, your TV may need to be updated with the most recent firmware.

To update your TCL TV’s firmware, use your remote control to navigate to ‘Home’ > ‘Settings’ > ‘System’ > ‘System Update’ > ‘Check Now,’ which will cause your TV to manually check for updates.

If an update is found, it will be downloaded and installed automatically. You will then have to wait for your TV to reboot on its own, which could take a few moments, so give it some time before attempting to turn it on on your own.


There are a few different ways to get the blinking light to stop if you want to simply turn it off rather than investigate why it is happening. Look below for help troubleshooting your blinking light problems.

If the light on your TCL TV is blinking and won’t turn off, use your remote to turn it off. To do so, press ‘Home’ on your remote control, then ‘Settings’ > ‘OK’ > ‘System’ > ‘OK’ > ‘Power’ > ‘OK’ > ‘Standby LED’ > ‘OK’ > ‘OFF’ > then press ‘OK’ on the remote to confirm that you want the light off. This should stop the light from blinking by turning it off completely.

If you go into your TV’s settings menu and discover that there is no option to turn off the light, this could be due to a manufacturing detail that was not yet implemented on older TVs.

To turn off your TCL TV without this setting, press the ‘Home’ button five times > press the ‘Fast Forward’ button > press ‘Rewind’ > press ‘Play’ > press ‘Fast Forward.’ From the menu that appears, set the LED brightness to 0% to disable the light.

If your TCL TV has a blinking light and is not working, it is most likely in need of a hardware reset. To do so, locate the small reset button on the back of your television. Press and hold the reset button for 10 seconds with a paperclip or pen. This may need to be repeated several times.

The reset button can be difficult to locate, but it is usually located near the RCA, HDMI, and USB ports on your television. If a hardware reset does not work, you should power cycle your television.

Unplug your TCL TV from the wall for at least 30 seconds to accomplish this. After the full 30 seconds have passed, press and hold the TV’s Power button for 10 seconds. If the reset and power-cycle steps do not resolve your issue, it is most likely due to a faulty backlight on your television.

You can try to fix it yourself if you’re handy and have the patience. Otherwise, you should consider sending your TV in for repair. Before purchasing a new television, contact TCL television support and check your warranty to see if any repair/replacement costs are covered!
