Understanding the Issue: What Causes Horizontal Lines on a TV?
Horizontal lines on a TV screen can manifest in various forms, from faint streaks to prominent banding across the display. Understanding the root causes of these lines is essential for effective troubleshooting and repair.
1. Physical Damage
One of the most common causes of horizontal lines is physical damage to the screen. This can occur due to drops, impacts, or pressure on the TV surface. Physical damage can disrupt the connection between the screen’s pixels, leading to display issues.

The source of the input can also play a role. If the device connected to your TV (like a gaming console or cable box) is malfunctioning, it might output a distorted signal, resulting in horizontal lines being displayed on the screen.
Troubleshooting Steps to Consider
Before you seek professional help, several troubleshooting steps can help identify and possibly fix the issue with horizontal lines on your TV.
1. Check the Connections
Start by inspecting all the connections to your TV:
- Unplug and replug all cables securely, including power, HDMI, and any other input connections.
