A partially blacked-out screen can be one of the most frustrating issues for TV owners.

For Sansui TV users, professional repair is the most reliable solution.

In this article, we explore the common causes of partial blackouts, the repair solutions offered by the Sansui TV Service Center, and specific services available in Thane, Mumbai, and Bengaluru.

Understanding Partial Screen Blackout in Sansui TVs

Partial screen blackout is when a portion of the TV screen stops displaying images correctly, appearing black or dim while the rest of the screen works. This issue can occur in LED, OLED, or QLED TVs.

Common Causes of Partial Screen Blackout

1. Faulty LED/LCD Panels: Burned-out or damaged panels often lead to sections of the screen going dark.

2. T-Con Board Failure: The Timing Control board transmits signals to the display. A malfunctioning T-Con board can cause blackout in specific areas.

3. Backlight Issues: Uneven or failing backlight LEDs may result in portions of the screen not illuminating.

4. Loose or Damaged Cables: Internal ribbon cables connecting the display may be loose or damaged.

5. Power Supply Problems: Irregular voltage can affect certain sections of the screen, leading to partial blackouts.

Identifying the cause is crucial for effective repair, which is why professional inspection is recommended.
