Main Board (PCB Assembly)
The Main Board acts as the logic controller for the power-on sequence. A blinking red light typically indicates that the board's protection circuit has detected a fault during the power-up handshake, often due to a failure in the board's processor or a miscommunication with the panel. Replacing the Main Board is the primary fix for logic-related power-cycling issues.

Power Supply Board (SMPS)
If the power supply fails to provide the consistent 'Power-On' voltage (A5V or B13V rails) to the Main Board, the system will error out. This board converts AC to DC, and failing capacitors or MOSFETs on this board are a common secondary cause for the red light blinking symptom.

Internal Ribbon Cables (LVDS/FLEX)
The Q60A series often experiences shorts in the connection between the Main Board and the Panel. If these cables are seated poorly or have developed micro-shorts, the Main Board will detect the impedance mismatch and enter a protection loop (blinking light) to prevent further hardware damage.
