If your Roku TV screen is black but you can still hear sound, there are a few potential reasons and troubleshooting steps you can take to resolve the issue:
1. Check the Connections
- Loose or Damaged Cables:
- Ensure all HDMI and power cables are securely connected.
- Check for any visible damage on the cables and ports.
- HDMI Port Issues:
- Try using a different HDMI port on your TV.
- Swap out the HDMI cable to see if it resolves the issue.
2. Power Cycle the TV
- Restart the TV:
- Unplug the TV from the power outlet.
- Wait for about 60 seconds.
- Plug the TV back in and turn it on.
3. Check for Software Updates
- Update Firmware:
- Press the Home button on your Roku remote.

- Choose the display type that matches your TV (e.g., 1080p, 4K).
- Confirm and see if the display returns.
5. Test with Another Device
- Different Input Source:
- Connect a different device (like a DVD player, game console, or another streaming device) to your TV using the same HDMI port and cable to determine if the issue is with the TV or the Roku device itself.
6. Adjust Picture Settings

8. Hardware Issues
- Backlight Problems:
- If the backlight of the TV is malfunctioning, it might cause a black screen while the audio works. This typically requires professional repair.
- Internal Hardware Fault:
- There could be an issue with the internal components of the TV. If none of the above steps work, contacting Roku support or a professional technician for a diagnostic may be necessary.
9. Contact Support
