If your TCL Roku TV screen is black and there is no picture, even though the TV is running perfectly and you can hear the audio, then the problem is with the TV’s backlight, HDMI connection, or system software.
In most cases, if you can hear audio, the backlight is faulty.
But, if there is no sound coming out, there is an issue with the system.

What to Do If Your TCL Roku TV Doesn’t Display Any Picture on the Screen
Here are the detailed guidelines;
Step 1: Power cycle your TV
Let’s start with power cycling the TV.
I know this is something no one even wants to hear, but it really works.
The point is that most of the time, simply unplugging and then replugging the TV doesn’t actually work. So, you have to take this one step further by implementing a technique—”HDMI Refresh”
“Who knew the solution to my no-picture problem on my TCL Roku TV was as simple as power resetting? I feel like a tech genius now, but really it was just dumb luck.”
Anyway, here’s how to do this:
- Disconnect the TV from the power outlet completely.
- Similarly, disconnect all the HDMI-connected devices from the TV as well.
- Wait for at least 5 minutes. (Don’t compromise here)
- During this time, press and hold the TV’s power button for about 30 seconds.
- Once done, power the TV back on.
Now check if your issue has been fixed.
If power cycling doesn’t resolve the issue, proceed to the next step.
Step 2: Check the HDMI cable connection
If you’ve followed the previous steps and the problem is still occurring, check the HDMI cable connections.
HDMI connection is used to transmit audio and video between devices. If there is an issue with this cable, the TV will not get the proper signal to display content correctly.
First, ensure that all devices connected to your TV via HDMI have a solid connection. If the connections are secure, check a few other things like the HDMI ports.
If you suspect that the HDMI ports are the problem, you may need to have them repaired or replaced.
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.
So without a functioning backlight, the TV cannot display images.
It can become damaged due to various reasons, such as a power outage or problems with the unusual electric flow to the TV.
However, there is an easy way to determine whether the backlight is actually damaged or not.
- 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, 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.
Because attempting to fix the issue on your own can lead to further damage or injury.
Q: Why is my TCL Roku TV displaying no picture, but I can hear the sound?
There could be several reasons for this issue.
First, check if the TV is receiving a proper video signal. Ensure that the HDMI or other video input cables are securely connected.
Additionally, verify if the TV is on the correct input source.
Q: What should I do if my TCL Roku TV has no picture or sound at all?
If both the picture and sound are completely absent, the issue might be with the power supply or the TV’s internal components.
Make sure the TV is plugged in and the power source is working properly.
Try using a different power outlet or power cable.
Q: Can a software update fix the problem of no picture on my TCL Roku TV?
It’s possible that a software update could fix the issue, as some updates can address bugs and glitches.
However, if the problem is hardware-related, a software update is unlikely to resolve the issue.
Q: Is it worth repairing my TCL Roku TV if it’s not displaying a picture?
It depends on the cause of the issue and the cost of the repair. If the issue is minor and the cost of the repair is reasonable, it may be worth fixing.
However, if the repair is expensive or the TV is old, it may be more cost-effective to replace the TV.
