But what’s causing this sudden power loss? Could it be internal memory issues, overheating, or a TV driver problem?

Fear not, as I’ve created an extensive guide to help you troubleshoot and fix your TCL TV in no time.

Let’s get started!

TCL TV Turns Off By Itself

If your TCL TV turns off by itself, there are a few possible causes for this issue. To troubleshoot the problem, you can try resetting the TV, checking for overheating and updating the TV driver. If these steps don’t fix the issue, there may be a more serious problem that requires professional repair. Contact TCL customer support for assistance if needed.

TCL TV Turns Off By Itself

Here are the detailed causes with ways to fix that to solve the issue of TCL TV Turning on and then Off:

#1. Overheating of TCL TV

Extended Usage: Leaving your TCL TV on for extended periods of time can cause it to overheat. When the TV overheats, it will turn on and off immediately to prevent damage.

Blockages in Ventilation System: Blockages in the ventilation system can restrict airflow, causing heat to build up inside the TV. This can lead to overheating.

Hot Environments: Using your TV in a room that gets very hot, such as a sunroom or near a fireplace, can cause the TV to overheat.

How to Fix Overheating of TCL TV?

Here are the ways to fix TCL TV Overheating issue:

Identify the Cause: The first step to fixing the overheating issue is to identify the cause. If the TV is in a hot, humid environment, try to move it to a cooler location. If it’s in a cabinet or enclosed space, try to increase the airflow around the TV.

Clean the Vents: Dust buildup on the internal components can cause the TV to overheat. To fix this, clean the vents on the TV and ensure good airflow around the TV. Use a can of compressed air to blow out the dust.

#2. Faulty Power Supply

Another possible cause of your TV turning off immediately is a faulty power supply. If your TV is plugged into a power strip, make sure the power strip is turned on. 

How to Fix the Problem with Faulty Power Supply?

Firstly, check if your TV is plugged into a power strip and ensure that the power strip is turned on. If your TV is directly plugged into a wall outlet, you can verify if the outlet is working by plugging in another device.

In addition, it’s crucial to examine any loose connections as they can cause your TCL TV to turn off after it’s turned on. You can try plugging your TV power cable into different power sockets in your power outlet. If the issue persists, you may need to replace the power supply.

#3. Problem with TCL TV internal Memory

One possible reason for a TCL TV turning on and then off immediately is an issue with the internal memory.

This can happen if the internal memory is corrupted or full, which can occur due to cache build-up and software updates.

Smart TVs, including TCL TVs, often have low internal memory, making it easier for the memory to fill up quickly.

Additionally, there may be unused software installed on the TV that can take up valuable memory space.

How to Fix Problems with TCL TV Internal Memory?

If the problem is with the internal memory, you may need to reset the TCL TV. To fix this issue, you can try resetting the TCL TV to factory settings.

This will erase all of the data on the TCL TV, so be sure to back up any important data before resetting the TV.

As your TCL TV is not remaining on you can use the Reset Button on the back of the TCL TV to reset it. You need to locate the Reset Button on the TCL TV panel and press and hold using a clip, pen, or toothpick for 40-60 seconds. Your TCL TV would eventually restart after it is factory reset.

#4. TCL TV Driver Issue causing it to turn on then off immediately

If you’re using an older model of TCL TV, it’s possible that the drivers are outdated and need to be updated.

Also, the TV driver may have got corrupted which is causing it to turn off immediately after you turn your TCL TV on.

How to Fix the Problem with TCL TV Driver Issue?

If the problem is with the TV driver, you may need to update the driver or reinstall it. To do this, go to the manufacturer’s website and download the latest driver for your TCL TV model. 

Once the driver is downloaded, install it on your computer and then connect the TV to the computer using a USB cable. After the driver is installed, try turning on the TV again.

#5. TCL TV Infected With Virus

This often does not happen as we plug rarely an external device into our TCL Smart TV now.

Viruses or any type of malware can come from external devices like a Pen drive or external hard disk if that is already virus affected.

You may also bring viruses if you already have installed any other apps that are not from the Play Store on your TV.

How to Fix TCL TV Infected With Virus?

To fix it, the best way is to remove any external devices attached to the TV and format those devices and scan those using an Anti Virus in your Laptop or your PC.

Now, about your TCL Smart TV, do a factory reset. It will clean up all additional files that may be malware and bring the TCL TV back to as it was before.

#6. Issue With the TCL TV Hardware

If your TCL TV turns on and off immediately and you’ve already checked for overheating, driver problems, and power supply issues, it’s possible that the TV itself is the problem. This may occur occasionally.

How to Fix the Problem with Issue With the TCL TV Hardware?

First, check the warranty of your TCL TV. If your TV is under warranty, then you must contact TCL’s official customer support.

You can log a ticket to the TCL Support help desk too. You can also contact the customer support team via Twitter @TCLNA_Support.

If your TV is out of warranty, take your TCL TV to the repair shop nearby for them to get a diagnosis of the issue and get an estimate from them.

Cross-verify the estimate with official customer support and give it to repair.

Generally, this can get fixed at a low cost. Otherwise, you need to look for a new TV.
