Hyundai Tucson Screen Flicker Due to Coaxial Cable Fault

This is the primary cause of intermittent infotainment screen blackouts. Confirm this by checking for physical flickering or screen instability that worsens over uneven road surfaces or vibration. A technician can verify this by inspecting the coaxial cable connection behind the infotainment display; if the cable shield is loose or improperly seated, the signal between the head unit and the display module is interrupted, causing the screen to turn black or flicker.
