Power Supply Board
The blinking red light signifies the TV has entered a protection mode due to an over-current or under-voltage condition. This is most frequently caused by failing filter capacitors or a defective MOSFET on the power supply board that cannot sustain the transition from standby power to operational voltage levels.

Main Board
If the PSU is delivering correct voltages, the blinking light indicates the Main Board's system-on-chip (SoC) is failing to complete the boot cycle. This often occurs due to corrupted EEPROM data or thermal fatigue of the BGA solder joints on the primary processor.
