Sony Sony VPL-XW5000ES Native 4K SXRD Laser Home Theater Projector WARNING FLASH Error Fix: Temperature Warning — WARNING LED Flashing

The WARNING indicator LED on the projector is flashing orange. The projector has detected that the internal temperature is approaching the upper safe operating limit. The cooling fans will increase speed to compensate. If the temperature continues to rise despite increased fan speed, the projector will shut down automatically to prevent heat damage to the laser light source and optical components. Clear any obstructions from the air intake and exhaust ventilation ports on the projector body. Ensure at least 12 inches (30 cm) of clearance around the projector on all sides. Clean accumulated dust from the air filter and ventilation openings — dust buildup is the most common cause of temperature warnings. Reduce ambient room temperature if it is excessively hot. If the projector is ceiling-mounted, ensure the mounting enclosure (if any) allows adequate airflow.
