Check the Power Supply

- Next, try connecting your Hisense Smart TV to a different power outlet. Once done, boot up your TV and see if the issue is resolved.
Diagnose the HDMI Cables / Port
- Horizontal lines on a Hisense TV may appear due to loose or dusty HDMI cables. Start by disconnecting all HDMI cables from the TV and inspecting the ports and cable connections for dust. After cleaning, reinsert the HDMI cables into their respective ports.
- If the problem persists, try using a different HDMI port on the Hisense TV.
- If the HDMI cable is damaged, replace it with a new one and check if the problem is resolved.
Power Cycle Hisense Smart TV
Sometimes, horizontal lines on your Hisense TV screen are caused by software bugs. If this is the case, you can often fix the issue by restarting your Hisense Smart TV. After the reboot, check if the horizontal lines are still present. If the problem persists, proceed to the next solution.

If horizontal lines appear only on specific parts of the screen, it may indicate damage to the ribbon cables. Follow these steps to address the issue:
- Unplug your TV and remove the back panel.
- Identify the ribbon cable corresponding to the area of the screen with horizontal lines.
- Use a small piece of tape to cover the contact points on the ribbon cable.
- Close the back panel and check if the issue persists. If the problem continues, it may be due to an issue with the TV board. In this case, visit a nearby service center for further assistance.
