Line Issue Repair

Vertical or horizontal lines on a TV screen are among the most common display issues faced by LED, LCD, QLED, and OLED televisions. These lines may appear due to problems in the panel’s internal connections, loose or damaged COF (Chip-On-Flex) bonding, faulty T-CON board, or pixel driver failures. Sometimes the issue may start with a single thin line and gradually spread across the screen, disrupting the viewing experience. Environmental factors such as moisture, accidental pressure on the screen, and long hours of usage can also contribute to the development of these line defects.

At our service center, we perform a complete diagnostic check using advanced test equipment to identify the exact cause of the line issue. Instead of immediately suggesting costly panel replacements, we use specialized tools such as COF bonding machines, panel heating devices, and micro-soldering instruments to fix the problem at the component level. Our technicians carefully inspect each ribbon cable, driver IC, and T-CON signal to restore proper synchronization between the TV’s processing board and the display.

In many cases, line issues can be repaired without replacing the entire panel, making the process highly cost-effective. We focus on delivering long-lasting repair solutions, ensuring your TV regains clear picture quality and performs smoothly. Whether your TV shows intermittent lines, full-line bars, or half display problems, our expert team provides reliable and professional service with genuine parts and guaranteed results.
