Main Logic Interface Board
The Main Logic Board contains the Power Delivery (PD) controller and the Configuration Channel (CC) logic required for the USB-C handshake. Failure in these components prevents the monitor from negotiating the 15V or 20V power profiles needed to charge a laptop, even if the data pins and basic monitor power remain operational.

USB-C to USB-C 3.2 Gen 2 Cable
USB-C charging requires an E-Marked cable to handle high wattage; mechanical fatigue in the internal shielding or a failure in the cable's integrated circuit can prevent the 'SOP' (Start of Packet) communication required for Power Delivery, resulting in video-only or no-power scenarios.
