After doing some research on TCL’s website and TV forums, I found several possible reasons for this issue.

Some TV owners reported that it could be due to a bad cable connection, a faulty power supply, a faulty circuit board, a loose or broken HDMI cable, a flawed display panel, or a malfunctioning backlight.

Sometimes, you may experience that your TV’s sound is running, but the display is black. This can be caused by various factors, including damage to the TV’s display, problems with the cables or connectors, a software issue with the TV, or incorrect or damaged input connections.

Troubleshooting TCL Roku TV no Picture issue

To troubleshoot the “no picture” issue on your TCL Roku TV, try power cycling it. To do this, unplug your TV from the power source and wait two minutes before plugging it back in.

Now, let’s delve further into some possible solutions in detail. Before we begin, take a look at the table below for a clearer understanding.

Reasons Solutions
Functional glitch Power cycle your TV
Bad HDMI connection Check and replace it
Faulty backlight Replace it

Step 1: Power cycle your TV mark

Power cycling is a technique that involves turning a device off and then on again. This simple step can often resolve issues with devices, including TVs. Many TCL Roku TV owners have reported that power cycling has successfully fixed various problems in almost 95% of cases.

One reason why power cycling works is that TVs can be prone to damage from power outages or sudden impacts, which can cause stored data in the TV’s memory to become corrupt or malfunction. By power cycling the TV, you are essentially rebooting the firmware and functional file, which can fix the issue.

I also succeeded with this method when I encountered this issue with my TCL TV. Fear not; performing a power cycle will not erase your downloaded content or settings.”

Here’s how to power cycle your TCL Roku TV

  • Turn off the TV and unplug it from the power outlet.
  • Wait for at least three minutes before plugging it back in.
  • Once the required time has passed, turn on the TV.

Now check if your issue has been fixed or not. If power cycling the TV didn’t resolve your issue, don’t worry – there are still more steps you can try in troubleshooting. Proceed to the next step.

Try factory resetting your TV as well. It’s possible that this could fix your issue. Follow this link for a step-by-step guide on how to reset your TV.

Step 2: Check the HDMI cable connection

If you’ve followed the previous steps and the problem is still occurring, check the HDMI connections. HDMI stands for High-Definition Multimedia Interface, and it’s a type of connection used to transmit audio and video between devices.

First, ensure that all devices connected to your TV via HDMI have a solid connection. This means that the HDMI cables are securely plugged into both the TV and the device and that there are no loose connections.

If the connections are secure, you should check a few other things. One possibility is that the HDMI ports themselves may be faulty. This can be caused by wear and tear over time or by using the ports to connect and disconnect devices frequently. If you suspect that the HDMI ports are the problem, you may need to have them repaired or replaced.

Another potential issue is that the HDMI cable itself may be bad. HDMI cables can go bad due to age, wear and tear, or exposure to elements such as water or heat. If you suspect that the HDMI cable is the problem, try replacing it with a new one and see if that resolves the issue.

TCL TVs often have multiple ports, sometimes up to four, so try using a different port and see if this resolves the issue before replacing the HDMI cable or repairing HDMI ports.

Step 3: Check the TV’s backlight

Backlight is a crucial component that helps illuminate the screen and make the images visible to the viewer. Without a functioning backlight, the TV cannot display an image.

TV’s backlight can become damaged due to various issues, such as a power outage or problems with the electric flow to the TV. If the backlight is damaged, you must replace it in order to get the TV working again.

However, there is a way to determine whether the backlight is actually damaged or not. Here’s how to check it:

  • First, make sure that the TV is powered on.
  • Then, take a flashlight and hold it close to the screen.
  • As you shine the flashlight on the screen, carefully observe whether any image is visible.

If you can see a faint picture on the screen when the flashlight is shone on it, this indicates that the backlight needs to be replaced.

Did nothing work?

If you have attempted all the troubleshooting steps listed above and are still experiencing issues with your TV’s display, the T-con board or other components related to the display may be damaged.

In this situation, it is advisable to contact TCL customer service for additional support. Alternatively, you can visit a local TV repair shop and speak with a technician about the problem. It is always recommended to seek professional help when dealing with potential damage to electronic devices, as attempting to fix the issue on your own can lead to further damage or injury.

Yes, it is possible that the lack of a picture on your TCL Roku TV could be due to a problem with the HDMI connection. However, it could also be a problem with the TV itself, such as an issue with the display or a malfunctioning component.
