TCL Roku TV Light Blinking Won’t Turn on (Fixed)

If your TCL Roku TV light is blinking red, it means the TV is stuck in standby mode and needs your help to get out of this situation.

But if the light is blinking red and the TV isn’t turning on, the LED backlight, inverter board, or the power supply unit is most likely faulty.

Anything could be…

In this article, I will break down everything about why your TCL Roku TV light is blinking and exactly what you have to do to troubleshoot this issue.

Let’s dive in…

How To Fix This Issue?

  • Press the power button.
  • If it flashes red and the TV won’t turn on, the problem is with the power board.
  • If the power button remains solid red, the TV’s main board is faulty.
  • Replace the faulty board.


Here are the detailed guidelines:

Step 1: Turn Off the Standby LED

This is especially for those, whose TV’s light is blinking but the TV is working properly.

Again, the TV is working correctly!

This feature is included in TCL TV so that you can identify the technical issues. But if it continuously flashing or you are getting irritated, simply turn this off.

Here’s how:

  • Press the ‘Home‘ button and access the ‘Settings‘ menu.
  • Scroll down to the ‘System‘ option.
  • Under the ‘System‘ menu, select the ‘Power‘ tab.
  • Look for the ‘Standby LED‘ option and navigate to it.
  • Press the right navigation button to turn off the standby light.
  • Press the ‘OK‘ button to confirm your changes.

That’s it.

Note: The LED light will also blink every time you press the remote button to operate the TV, even if you have followed these steps. This is to indicate that the command has been received.

Step 2: Power Cycle the TV (Don’t Skip)

This is something no one even wants to hear.

But it works.

The reason is that if your TCL TV is blinking a red light due to a system glitch, this simple restart will reset all the internal components like capacitors and transistors, fixing the glitch.

Here’s how:

  • Completely disconnect the TV from the power outlet.
  • Similarly, disconnect all HDMI and USB devices connected to the TV.
  • Wait for 5 minutes. (Be patient)
  • During this time, press and hold the TV’s power button for about 30 seconds.

Once done, power the TV back on. Now check whether the light is still flashing.

Step 3: Factory reset your TV

If power cycling doesn’t work, a factory reset might help!

If you cannot enter the settings menu of your TV or your TV doesn’t turn on at all, reset the TV to its default settings.

Remember to save important settings and back up data before resetting the TV because it will erase all of your TV’s settings and return it to its original state.

However, if you are unsure how to factory reset your TV, consult our previous post for a step-by-step tutorial from this link.

In my observation, when the TCL Roku TV light blinks red and the TV won’t turn on, the main control board or the power board is most likely the main culprit. Therefore, the only solution is to have it replaced by a technician.

Did Nothing Fix Your Issue?

If none of those mentioned troubleshooting steps help you to fix the issue, then you have two options left.

♦ Check the TV’s backlight

TV backlights can be damaged for various reasons, such as sudden electrical surges or other unexpected events.

This type of damage is quite common and can have serious consequences for the functioning of your TV.

If the backlight is damaged or if one of its LED strips stops working, your TV may start to blink, indicating that its backlight needs to be repaired.

However, refer to our guide to fix backlight-related issues with your TV.

♦ Contact TCL customer care

If the problem is not related to the backlight or software, it means that one of the internal components of your TV has been damaged.

If you do not have the necessary skills or knowledge to perform DIY repairs, it is best to contact a professional repairer to diagnose and fix the issue.

You can also contact TCL customer care if your TV has a valid warranty, or you can visit the TCL Q&A page and directly type your query and search for fixes.


Q: Can a faulty HDMI cable cause a blinking light on my TCL TV?

It’s unlikely.

While a faulty HDMI cable can cause issues with the sound or picture quality, a blinking light on your TCL TV is more likely to be caused by a power supply or circuit board issue.

Q: Can a problem with the remote control cause a blinking light on my TV?

No, a blinking light on your TCL TV is typically related to a power supply or circuit board issue and is not caused by the remote control.

Q. Is it normal for my TCL Roku TV to have a blinking light when it’s not in use?

It is normal for some TCL Roku TVs to have a blinking light when not in use. This is usually a power indicator light, which indicates that the TV is still receiving power.

If the light is flashing rapidly or if you are experiencing other issues with your TV, it may be a sign of a problem, and you should first try the troubleshooting steps mentioned above.

If it does not work, contact a TV repair technician for assistance.
