Sony Sony XR-55X90K 55-Inch 4K Full Array LED BRAVIA XR Smart TV 7 BLINKS Error Fix: Standby LED Blinks 7 Times — Thermal Protection Shutdown

Error code 7 BLINKS on the Sony Sony XR-55X90K 55-Inch 4K Full Array LED BRAVIA XR Smart TV means: Standby LED Blinks 7 Times — Thermal Protection Shutdown. The standby LED blinks 7 times, pauses, then repeats. Seven blinks indicates the TV has shut down because internal temperature sensors detected a temperature exceeding safe operating limits. This is a protective shutdown to prevent heat damage to internal components. Common causes include operating the TV in an enclosed cabinet or entertainment center with insufficient ventilation, mounting the TV flush against a wall with no gap for airflow, a failed internal cooling fan (on models equipped with active cooling), or ambient room temperature exceeding the TV rated operating range (typically up to 40 degrees Celsius or 104 degrees Fahrenheit). The TV will usually power on normally after it has cooled down sufficiently. Ensure at least 4 inches of clearance around all ventilation openings.
