T-Con Board (Timing Controller)
The T-Con board regulates the specific voltages required for the organic light-emitting diodes to function. The 4-blink code is a safety shutdown triggered when the board's monitoring circuit detects a deviation in the panel's power consumption or a failure in the communication between the Main Board and the panel. Replacing this board resolves the error by restoring stable voltage regulation and proper feedback signals to the TV's central processor.

Main System Board
If the T-Con board is functional, the 4-blink sequence can be caused by a corrupted boot sequence or a failure in the Main Board's ability to process the 'Power-On' handshake from the display's logic. This results in the system misinterpreting the panel's status and defaulting to a protection state to prevent hypothetical hardware damage.

OLED Display Panel Assembly
In cases where thin lines were visible prior to the failure, the root cause is an internal electrical short within the OLED matrix itself. This short causes a current spike that the T-Con board detects, triggering the 4-blink protection mode; in this scenario, the entire panel assembly must be replaced as the internal circuitry is non-serviceable.
