TCL TV Light Blinking
If the TCL TV light is flashing, make sure your TV is connected to a network. If it isn’t, connect it right away. Then, ensure your remote uses fresh batteries. You can also power cycle your TV to soft reset it, as it can resolve 80% of blinking issues.
Make sure to soft reset your TV a couple of times to get it back up and running. If that doesn’t work, try resetting your TV to factory defaults as your last resort before contacting TCL support.
Why Is My TCL TV Light Blinking
If the TCL TV light blinking or flashing, it could be due to the following reasons:
- Your TV is stuck in standby mode
- TV software is outdated
- Using a damaged wire
- Hardware component issues
- The remote is either not connected or working
Either way, you need to troubleshoot the error to fix it. Below, we’ve shared a list of proven hacks and troubleshooting methods that you can use to fix TCL TV light-blinking issues.
How to Fix TCL TV Light Blinking
1. Soft Reset Your TCL TV
If you’re experiencing the “TCL TV light blinking” issue, try soft resetting your TV. Here’s how to power cycle your TV.
First, disconnect your TCL TV from the power socket and leave it for one minute. Once the time is up, hold down the power button for 20-30 seconds.
Press the power button on your TV instead of its remote. This will consume any residual power stored in your TV and let it soft reset itself.
After a whole minute, try plugging your TV back in and see if it fixes the blinking issue. If it doesn’t, move on to the next hack.
2. Reseat All Cables
The TCL TV light blinking error can also occur due to loose cable connections. It can cause your TV to search for signals and, as a result, it will show a blinking light.
So, unplug all TV cables and reseat them to ensure all connections are tight. If you have a faulty wire, replace it with a new one.
I also tried swapping some cables with my extras just to make sure the ones I was using were functioning.
3. Pair Your Remote
Sometimes the blinking light error may occur due to an unpaired remote. So, pair the remote with your TCL TV by pressing the pairing button. Your remote will automatically search for and pair with your TV. Hopefully, this will resolve the blinking light issue on your TV if it doesn’t, move on to the next hack.
4. Clear TV Notifications
The TV will pop up notifications regarding new updates, features, etc., just like your smartphone. So, if you don’t clear or read those notifications, it may appear as a blinking light.
If you don’t want to get annoyed by the constant blinking light, it’s best to clear the notification and see if the issue is resolved.
5. Update TV Software
If your TCL Roku TV light is blinking, it could be due to outdated TV software. The blinking light may be a constant reminder to update your TV software. So, you should open the update section and update your TV to resolve this issue.
6. Backlight Is Not Working
Even after power-cycling or resetting your TV, your TCL TV may have a backlight issue if you’re still getting the blinking light and it won’t turn on.
Backlight problems are common in TCL TV models and are often due to faulty backlight strips.
Remember that fixing the backlight issue on your TCL TV is a little bit trickier but not impossible. You have to disassemble your TCL TV take out the faulty backlight strip, replace it with a new one, and reassemble your TV.
If you have access to the necessary tools, here’s a video tutorial on how to fix TCL TV light blinking issues instead of buying a whole new TV.
Unlike other troubleshooting methods, repairing a backlight requires patience and experience with the necessary tools. So, it would be better for you to get it repaired by an expert technician.
7. Use the Reset Button on Your TCL TV
On some TCL models, it’s a little trickier to locate the reset button. Fortunately, some models use labels to highlight the button and make it easier for users to find it.
Often, the reset button is integrated right next to USB, HDMI, and RCA ports. Remember that some TCL TV models have these buttons on their left side, while others have them at the center or on the right side.
After finding these ports, look for a pinhole reset button next to them. Or read the label that says reset.
Once you locate the button, use a pin or toothpick to hold down the button for at least 10 seconds and see if it resolves the issue. Make sure to repeat the process 4-6 times to fix the blinking issue.
If that doesn’t work, try hitting the reset button simultaneously 25–30 times. In most cases, this would resolve the issue. If not, contact TCL support for further assistance.
8. TCL TV Support and Warranty
If none of the above methods have worked for you, try contacting the TCL TV support line at 1-877-300-8837. They can process your query in the following working hours.
