If you can turn on your TCL TV without issue, the power light on your TV should illuminate with no blinking or flickering as your TV remains turned on. However, users have reported issues with the power light blinking and flashing while they watch TV without incident.

If you’re having the same issue, you might be wondering what’s causing it, and a few solutions can be found below. If your TCL TV light continues to blink or flash, it could be because you haven’t yet connected to your wireless or wired internet and it is looking for a signal.

To check if you are connected, use your remote control to navigate to ‘Home’ > ‘Settings’ > ‘Network’ > ‘Wireless’ > and you will either see if you are connected to the internet or your TV will begin to scan for your wireless network, which you can then configure.

If you are using an ethernet cable, find the ethernet port on the back of your TCL TV and connect the ethernet cable which comes from either your router or modem to the TV. Then, press ‘Home’ on your remote > ‘Settings’ > ‘Network’ > ‘Wired (Ethernet)’ > and then the connection will be verified if you are just setting up or if things are working properly.


It is always a good sign if your TCL TV will turn on without any issues, but what do you do if the TV simply refuses to turn off and the light on your TV is also blinking? You’re left with a signal that appears almost unintelligible, but there are a few things you can try to turn off your TV and stop the light from blinking.

If your TCL TV light is blinking and the TV won’t turn off, it could be because your remote isn’t working properly. One of the most basic and often overlooked issues is simply replacing the batteries in the remote.

Simply remove the old batteries and replace them with good-quality batteries that will allow your remote to work at full strength so that the signal reaches your TV. If this isn’t an issue for you, try turning off the TV manually from the back or along the bottom.

You can also try to manually reset the TV by finding the reset button on the back or bottom, inserting a paperclip into the recess on the reset button, holding for 15 seconds, and then releasing. This should assist you in manually resetting your TV, which should resolve the blinking light and allow you to turn it off.


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 keeps flashing black, a power cycle may help to correct any small glitches that have found their way into your TV.

To complete a power cycle, reference back 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 issue, your TV may need to be updated with the latest 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.

1. Check your input cables

The most common cause of your light blinking on a blank screen is that your TV is not receiving the proper input from the cables. This can put your TV into search mode, causing the light to blink indefinitely. To avoid this problem, make sure your PC’s input cables are properly connected and that the set is receiving the correct signals.

Keep in mind that the blinking light could also be an indication of a network outage from your service provider. In any case, unplugging the cable and reattaching it tightly should resolve the problem. The reset button is usually located right next to your RCA, HDMI, and USB ports.

These connections can be found on the right side of some TCL televisions. Others can be found on the left side or beneath the front paneling.

Once you’ve found these ports, start looking for a tiny reset button. I’ve included a few examples of TCL TV reset button locations below to help you find what you’re looking for.

2. Remote not connected

If the light is blinking but your screen is functioning normally, this could indicate that some of the components are not properly connected. This could be due to your remote being disconnected. You must ensure that your remote is in good working order, that it is paired, and that it is connected.

If this is not the case, press and hold the pairing button on your remote to connect it to the TV. Your light will stop blinking once it is connected. The blinking light could also indicate a low battery, a weak signal from the remote, or another problem.

3. Restart your TV

If you are not able to find any apparent reason for your light to blink continuously and everything seems to be working fine, try restarting your set. This will reboot all components and should solve any hardware issues.

4. Check notifications

The light blinking can sometimes be an indication that you have an important notification to check. It is critical that you monitor your notifications for important messages.

If you find that they are interfering with your viewing experience, you can disable them by going to your settings, but you will need to manually check notifications to avoid missing important messages that could interfere with your viewing.

5. Reset the TV

Sometimes resetting your TCL TV will be the only way to fix the issue. This is a simple process and does not require any technical expertise. To reset your TCL TV:

  1. Go to the Settings app
  2. Navigate to the reset options
  3. and click on ‘Reset to Factory Settings.’

It may take a while, but after your TV restarts, you should be able to see the menu as before, but the blinking light should be gone.

6. Update Firmware

If your TCL TV is still not working, you may need to update your firmware as the light could be notifying you about a pending update. You will need to check the update section and update your firmware in order to fix the issue.


You can also try calling the TCL television support line at 1-877-300-8837. Their operating hours are as follows:

  • Monday through Friday, 9 a.m. to 12 a.m. ET

TCL support staff is trained to deal with television issues like this and has most likely dealt with many similar complaints in the past. They should be able to walk you through some troubleshooting steps to determine whether this is something you can fix yourself or if it needs to be sent in.


As a last resort, it might be worth checking to see if your TCL TV is covered under warranty. If you decide to investigate this further, here is all the warranty information you’ll need. For the first year of ownership, most TCL TVs are covered by a limited warranty.

“Defects in materials or workmanship to the original owner of this TCL product when purchased as new from an Authorized Dealer,” according to the warranty.

Basically, if they decide that the problem is covered, they will either pay to repair your TV or buy you a new one. Most likely, you’ve had your TCL TV for more than a year, but if not, it’s worth a shot!


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! I hope you found this useful.
