This issue is common and has been discussed in multiple user threads across various brands, including TCL Roku TVs.
Troubleshooting Steps:

- Power Cycle the TV: Unplug the TV from the power outlet for at least 30 seconds before plugging it back in.

Troubleshooting Steps:
- Check Resolution Settings: Ensure the TV’s resolution settings match those of the connected device. Navigate to Settings > Display type and select the appropriate resolution.
- Inspect and Replace HDMI Cables: Faulty or low-quality HDMI cables can cause image distortion. Replace the HDMI cable with a new one to see if the issue resolves.

Audio Device Connectivity

Backlight and Hardware Issues
When dealing with a Hisense Roku TV with sound but no picture, one of the primary areas to investigate is the backlight and hardware components. Backlight issues are common culprits in such scenarios.
Backlight Failures
A backlight failure is often indicated when the TV plays sound, but the screen remains black. This issue may stem from several causes, including water damage, power surges, or physical damage to the TV. A simple way to diagnose a backlight failure is by shining a flashlight on the screen. If you can see faint images when doing this, it likely means that the backlight is not functioning (Roku Community).
Common causes of backlight failures in Hisense TVs include:
- Water Damage: Exposure to moisture can short circuit the backlight components.
- Power Surges: Sudden power spikes can damage the backlight circuitry.
- Physical Damage: Any form of physical impact could damage internal components, including the backlight (9meters.com).
Backlight Testing Methods
Testing the backlight is essential to confirm if it is indeed the issue. Here are some methods for testing the backlight:
Flashlight Test
- Turn off the room lights to create a dark environment.
- Turn on the TV to ensure it is producing sound.
- Shine a strong flashlight directly onto the screen from a close distance.
- Look for faint images or shadows on the screen.
If you see any faint images, this confirms that the backlight has likely failed (9meters.com).
Power Cycling
- Unplug the TV from the power source.
- Wait for at least 60 seconds.
- Plug the TV back in and turn it on.
Sometimes power cycling can reset the backlight driver, bringing it back to functionality (9meters.com).
HDMI Connection Check
- Check all HDMI cables to ensure they are securely plugged in.
- Reconnect the HDMI cables firmly or try using a different HDMI port.
Faulty or loose HDMI connections can sometimes mimic backlight failure by causing no picture to display on the screen (9meters.com).
