Digital Main Board (HDMI Board)
The Digital Main Board houses the HDMI switching matrix and the CEC/ARC control processor. In this model, glitches are frequently caused by the failure of the HDMI IC to maintain the 5V logic high required for the DDC (Display Data Channel) handshake, or physical degradation of the TMDS differential pairs which prevents stable HDCP authentication. Replacing the entire digital assembly ensures the logic processor and HDMI ports are operating on a synchronized clock.
