Identifying the Issue
Symptoms of Horizontal Lines
Horizontal lines on a Vizio Smart TV can manifest in several ways. One common symptom is the appearance of faint lines that run horizontally across the screen. These lines can be intermittent or persistent, and may vary in thickness and color. A more severe symptom is a dark horizontal “bar” covering a portion of the screen, often a third. This issue points to problems with the LCD panel processing (JustAnswer).
In other cases, users may notice flickering horizontal lines, which may be more pronounced when the TV is displaying bright images. These lines can disrupt the viewing experience and may even indicate underlying hardware or connectivity issues.
Common TV Models Affected
Certain Vizio models are more prone to experiencing horizontal lines on their screens. Below is a list of commonly affected models and the symptoms reported:
| Model | Symptom |
|---|---|
| Vizio E470i-A0 | Dark horizontal bar covering one-third of the screen |
| Vizio 55″ Smart TV | Persistent horizontal lines |
| Vizio sv470m | Flickering horizontal lines |
Users of these models often report issues related to faulty display panels, loose connections, and overheating of internal components. For example, the E470i-A0 is known for its dark horizontal bar, indicative of a failed LCD panel often requiring replacement of the entire screen.

To adjust resolution settings:
- Access the display settings on your connected device.
- Identify the resolution setting and adjust it to match the TV’s native resolution.

Consider TV Upgrade
Persistent horizontal lines on the screen could signal deeper issues, such as a malfunctioning LCD panel or timing control (t-con) board. In some cases, this problem manifests as a dark horizontal “bar” covering a portion of the screen, notably in Vizio TV models like the E470i-A0 (JustAnswer).
| Model | Common Issues | Solution |
