Understanding TV Horizontal Lines
Causes of Horizontal Lines
Horizontal lines on iFFALCON TVs, as well as other models like TCL, RCA, and LG, are a common issue that can be frustrating for owners. These lines can be caused by several factors, most often related to hardware malfunctions. One prevalent cause is a failed or failing tab gate driver on the LCD panel. The tab gate driver is crucial for the display’s operation, and when it malfunctions, it can result in horizontal lines and flickering images. This issue isn’t limited to iFFALCON TVs; similar problems have been reported in brands such as samsung and sony (Jostewcrew).
Impact of Failed Tab Gate Driver
When the tab gate driver fails, it can significantly affect the display quality. The tab gate driver manages the electrical signals that control the pixels on the screen, ensuring images are displayed correctly and efficiently. If this component is compromised, you might see persistent horizontal lines across your screen, degrading the viewing experience. Fixing a failed tab gate driver can be problematic since the displays represent a substantial portion of the TV’s overall cost. In many cases, replacing the entire display might be deemed uneconomical compared to purchasing a new TV.
| Issue | Description | Potential Solution |
|---|---|---|
| Failed Tab Gate Driver | Causes horizontal lines and image flickering | Often uneconomical to repair, may require full display replacement |
| T-Con Board Failure | Causes horizontal and vertical lines | Replace T-Con board (cost-effective) |

Users have also reported successful resolutions by replacing the T-Con board.
