Sony Sony XR-65A80K 65-Inch 4K OLED BRAVIA XR Smart TV 8 BLINKS Error Fix: Standby LED Blinks 8 Times — Power Supply Board Failure

Error code 8 BLINKS on the Sony Sony XR-65A80K 65-Inch 4K OLED BRAVIA XR Smart TV means: Standby LED Blinks 8 Times — Power Supply Board Failure. The standby LED blinks 8 times, pauses, then repeats. Eight blinks indicates a critical failure on the power supply (APS) board. The power supply converts AC mains power (120V or 240V) to the various DC voltages needed by the TV main board, T-Con board, and backlight driver. Common points of failure include electrolytic capacitors that have dried out or developed swollen tops (visually identifiable by a bulging or leaking capacitor top), failed switching MOSFETs, failed diodes, and cracked solder joints caused by repeated thermal cycling over years of use. On some Sony models, swollen capacitors are the most common cause and can sometimes be individually replaced by a skilled technician or electronics repair shop at a fraction of the cost of a full power supply board replacement.
