One Connect 'Invisible' Cable
The hybrid cable carries both high-speed optical data and DC power. Mechanical stress, such as tight bends or pinching, causes internal fractures in the glass fibers or fatigue in the copper power conductors, leading to a complete loss of handshake between the processing box and the display panel.

One Connect Box Assembly
The One Connect Box houses the TV's main logic board and power supply. Thermal cycling can lead to solder joint failure on the BGA (Ball Grid Array) chips responsible for video processing, particularly if the box is placed in an unventilated cabinet, resulting in the system failing to output a signal through the proprietary port.

Main Interface Port (TV Side)
Frequent plugging/unplugging or the weight of the cable can strain the physical mounting points of the One Connect port on the rear of the TV panel. This causes cold solder joints where the connector meets the internal PCB, interrupting the LVDS data stream.
