When a TCL TV’s light blinks red, it typically indicates that the TV is stuck in standby mode.
In fact, this is a quite common issue not only among TCL users but also among other top brands like LG or Samsung.
However, troubleshooting this issue takes less than 5 minutes.
This guide will break down what the flashing light means on a TCL Roku TV and what you need to do to get your TV working again.
Let’s dive into it…
Understanding the blinking light issue
Typically, the blinking light on a TCL TV indicate one of two things:
- TV is in standby mode.
- There is an issue with the backlight or inverter board.
Look at this:
Reason for this issue | Description |
---|---|
Standby mode | The blinking light on a TCL TV simply indicates that the TV is stuck in standby mode and is awaiting for some force to turn on. |
Inverter board issue | In some cases, the blinking light on a TCL TV may indicate a problem with the inverter board, which is responsible for providing power to the TV’s backlight. |
Backlight issue | Similar to the inverter board issue, a blinking could also indicate a problem with the TV’s backlight, such as a burnt-out LED or other issues. |
Troubleshooting TCL Roku TV’s blinking light issue
To troubleshoot a TCL Roku TV whose light is blinking red, first disconnect the TV from the power outlet and wait for at least 60 seconds. During this time, press and hold the power button for about 15 seconds. Once you have done this, power the TV back on.
Below are the other available ways you can solve this issue:
Way 1: Turn off the Standby LED light
This step is especially for those, whose TV’s light is blinking but the TV is working properly.
However, while the standby light is included as a helpful tool for identifying technical issues with the TV, many individuals find it to be a nuisance.
If you are one of these people, there is a simple solution – you can easily turn off the standby light feature.
This will prevent the light from blinking and disturbing you while allowing you to access all of your television’s other functions and features.
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.
Warning: The LED light will 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.
Way 2: Factory reset your TV.
If power resetting doesn’t work, a factory reset might help!
If you are unable to 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.
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 actually 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.
