In this article, we’ll delve into the possible reasons behind these lines and explore ways to troubleshoot and fix the problem.
Understanding the Types of Lines on Your TV Screen
Before we dive into the causes, it’s essential to identify the type of lines you’re seeing on your screen. There are several types, including:
Horizontal Lines
Horizontal lines are the most common type and appear as straight lines running across the screen. They can be thin or thick, and their color may vary depending on the underlying issue.

Vertical lines, on the other hand, run up and down the screen and can be just as distracting as their horizontal counterparts.
Diagonal Lines
Diagonal lines are less common but can be just as annoying. They appear as lines running at an angle across the screen.
Pixelated Lines
Pixelated lines are characterized by a series of small, square pixels that appear as lines on the screen.
