TCL TV Won’t Turn On But Light Is On [Solved]

Let’s say you have prepared well for a movie night, kettle corn is all run out, and the lights are dimmed, but your TCL TV won’t turn on as usual, even though the white light at the front panel shines bright. 

Sounds terrible right? Don’t fret, there are many who own a TCL TV that has this problem.

Now this article will give you the possible reasons for this particular issue and the specific measures to keep the TV active again. 

The problem will be dealt with by the steps and lessons that have been done before so you get the chance to enjoy the shows you love.

Recognizing the Problem

The second scenario is when all TCL TV indicator lights are on, but the TV is not responding to the remote control or the buttons of the TV itself. 

It is frustrating. A pilot light might give the illusion that a television is working, but if it does not react to either the remote control or the buttons, something is amiss. 

Below, are common scenarios that make this situation happen in the Basic TCL TV troubleshooting guide:

Power Supply Problems

One common cause is a power supply problem. Whether the TV picture will start up is determined by the TV’s internal power supply. The TV power-on light may be lit up. 

 

But the TV is not executing its commencement routine or whatever causes picture output to happen. 

A faulty power cable, a broken socket plug, or wiring that is internal to the TV itself could all be the reasons for this.

Problems with the remote control backlash

In some instances, it might not even be the TV that has a problem. Your remote control may well need attention. 

This could be caused by: depleted batteries, a button stuck down, or, worst luck of all, total failure of the remote control unit.

Software issues

TCL TVs being smart devices may develop some bugs that might make them unable to turn on. 

This might happen after a failed firmware update or just as a result of the device experiencing software issues.

Hardware problems

 

Other hardware-related problems may include a defective mainboard, or a defunct display panel and these too will render the TCL TV inoperable. 

These sorts of failures are generally not apparent right away and will need probing further.

Overheating or overload protection

In case your TCL TV gets too hot, it will shut down automatically so that it does not get damaged. 

In this case, the power indicator light may still be functional but the TV will not respond at all.

Cables and connections

A faulty HDMI cable or other connection can sometimes confuse TV systems into arbitrary actions. 

More often than not, wires that are loose or have been damaged would interfere with the signal transmission. 

This would in turn cause the TV not to be able to recognize the input and hence start off correctly.

Personal Anecdote

A few months back, I was in a situation where my TCL TV was not switching on. It was Friday night and I was looking forward to catching up on a new series. 

When I turned the TV on and pressed the power button, the light flashed but the screen was blank. 

I panicked for a moment, but then I recalled some of the solutions I had learned about previously.

It was a real mess, but after some time I decided to make things right instead of contacting an expert immediately.

Step-by-Step Troubleshooting

Having gone through a few potential common ones, let us now turn our focus to actionable steps. 

You can ensure the troubleshooting and fixing of a TCL TV that has a light indicator but will not switch on.

Step 1: Check the Power Supply

 

Inspect the Power Cable

Confirm that the power cable is fully connected to the TV and the wall socket.

The edge of the cable should also be checked for visible damage. If there are specific frays or cuts, find a new one for the power cord.

Try a Different Outlet

Switch off the television and plug it into another outlet to eliminate outlet-related risks.

Also if you are using a surge protector or a power strip, skip that and try out plugging the TV into the wall socket directly.

Verify the Power Switch

There are some TCL televisions that have a physical switch on the unit itself, for instance, the power button. Check that the switch is in the ‘On’ position.

Step 2: Assess Normal Remote Control Functioning

Replace Batteries

When looking at the remote control panel, it is important to first check whether there are dead batteries in remotes and replace them.

Test the Remote

Then stand male in front of the tele and when she holds the power button of the remote control, if the tele does not turn on the physical power button on the tele shall be utilized.

Check for Stuck Buttons

It is also necessary to check if there is a pressed button in case the automatic changing of channels takes place.

Step 3: Complete the Procedure of Soft Reset

Unplug the TV

In this case, it is essential to unplug the appliance from the wall outlet as a means of disconnecting it from power.

Wait for a Few Minutes

In this case, it is also necessary to leave the TV unplugged for at least ten minutes as a means of deleting residual memory.

Plug It Back In

After waiting, it is possible to insert the connector once again into the power source and attempt turning the tele on using the remote as well as the physical button.

 

Step 4: Assessing Functionality Overheating

Inspect Vents

In this case, it is possible to examine the vents of a TCL television set to determine whether they have dust deposits. 

This makes their functionality ineffective because this can lead to the overheating of the television set and the need to switch it off completely.

Warming Up and Cool Down

If the TV proves to be too hot, let it cool off for a while before turning the device on again.

Step 5: Check the Connections and Cables

Examine the Cables Such as HDMI

I denote that it is essential to ensure that all HDMI and other connection cables are not loose. In this case, try different cables if you have spares.

Remove External Devices that are Plugged in

To confirm suspicions of the cause, power all external devices such as game consoles and streaming devices, if any, and remove them from the system.

Step 6: Updating the Firmware

Menu of settings Click on

If the settings menu can somehow be reached (maybe through the physical buttons on the TV), look for the option to update the firmware.

Updating Procedure or Guide

If there’s an available update, follow the prompts on the screen to download and install the update. This may fix the software-related bugs behind starting up the device.

Step 7: Factory Reset.

Prerequisites

Keep in mind that a factory reset will delete all of your personal preferences and data. Please confirm that you are ready to reinstall everything.

The Reset Option Can Be Located

When your television set allows for that, usually you can see the option of factory reset in the options menu under settings.

Resetting the Control

Read the on-screen instructions given on the device to finish up with the changing of the factory settings.

Step 8: Call the Assistance or Service

If your TCL TV still refuses to turn on, perhaps all options have been exhausted and one should consider reaching out to the TCL help desk, or even a professional. 

Try to be specific about what you have done so far to save time.
