TV sound but no picture

If your TV has sound but no picture, it usually indicates backlight failure, LED strip damage, display panel issues, or T-Con board faults. This guide explains all major causes and solutions.

When a TV plays sound but shows no picture, it means the internal display components are failing while the audio section is still active. Common causes include burnt LED backlights, loose T-Con board connections, damaged LED strips, or a faulty display panel.

A dark screen with faint light or barely visible shadows confirms a backlight problem. In older LED TVs, the probability of LED strip failure is very high. Technicians in ,Visakhapatnam often receive such cases, especially from Sony, Samsung, LG, and Mi LED TVs.

Expert repair engineers use tools to check voltage output from the power board, detect LED failures, inspect the T-Con ribbon cables, and test panel response. Based on the diagnosis, repairs may include backlight replacement, T-Con repair, or panel rejuvenation.

If ignored, the issue can spread to the power board or damage the panel permanently. Immediate repair ensures longer life and prevents higher repair costs.
