Main Board
The Main Board acts as the logic center of the television. If the system-on-a-chip (SoC) or the EEPROM hosting the firmware fails, the TV cannot transition from standby to the active state, resulting in a blinking error code as the system fails its initial self-test. Replacing this board restores the logic handshake required for the power-on sequence.

Power Supply Board
The Power Supply Board is responsible for converting AC wall power into DC voltage rails (typically 5V, 12V, and 24V). If the filter capacitors or the secondary-side diodes degrade, the board may provide standby power but fail to sustain the higher current required for full operation, causing the system to retreat into a protection loop.

LED Backlight Strip Kit
Vizio protection circuits monitor the current draw of the LED backlight array. If an LED in the series fails open or shorts, the constant-current driver detects an impedance mismatch and immediately shuts down the power rails to prevent a fire hazard, often signaled by a rhythmic blinking of the status LED.
