What to do if the Hitachi PJ-TX100 displays 'CHECK THE AIR FLOW'?
- CCharles CrossJul 30, 2025
If you're seeing a 'CHECK THE AIR FLOW' message on your Hitachi Projector, immediately turn the power OFF and let the unit cool down for at least 20 minutes. Then, check for any blockage of the air passage, ensure the air filter is clean, and verify that the surrounding temperature is not above 35°C. After confirming these points, you can turn the power back ON.
