Main Logic Board
The Main Board houses the HDMI 2.1 controller and the video processing engine. A failure in the Integrated Circuit (IC) responsible for timing synchronization or Fixed Rate Link (FRL) handshaking will result in intermittent signal drops and frame-rate instability, manifesting as flickering across various inputs.

Ultra High Speed HDMI 2.1 Cable (48Gbps)
OLED panels operating at 4K/120Hz require massive data throughput that exceeds the limits of standard HDMI cables. Signal attenuation or electromagnetic interference (EMI) in a low-quality cable leads to bit-error rate spikes, causing the display to lose and regain sync, which is the most common cause of perceived flickering in this model.

Power Supply Board (PSU)
The Power Supply Board provides the high-voltage rail required for OLED panel luminance. If the filter capacitors or voltage regulators on the PSU begin to drift, it can introduce ripple current into the panel's backplane, causing the organic LEDs to oscillate in brightness (flicker) rather than maintaining a steady state.
