Understanding the Causes of Lines on Your TV Screen
Before we dive into the fixes, it’s essential to understand what might be causing those pesky lines in the first place. Here are some of the most common culprits:
HDMI Connection Issues
One of the most common causes of lines on your TV screen is a faulty or loose HDMI connection. This is especially true if you’re using a long HDMI cable or if the connection is damaged. Check your HDMI cable and ports for any signs of wear or damage, and try switching to a different port or replacing the cable altogether.

If the resolution or aspect ratio of your TV is not set correctly, it can cause lines to appear on the screen. Make sure that your TV is set to the correct resolution for the content you’re watching, and adjust the aspect ratio to fit your screen size.
TV Settings and Picture Quality
Sometimes, lines on your TV screen can be caused by incorrect TV settings or poor picture quality. Check your TV’s picture settings and adjust them to optimize the display. You may need to adjust the brightness, contrast, or sharpness to get rid of the lines.
Signal Interference
Signal interference from other electronic devices can also cause lines on your TV screen. Try moving other devices away from your TV and see if that resolves the issue.
