Why is my projector making a static noise?

Why is my projector making a static noise? The fan is the most likely culprit: it’s the only mechanical item in the projector, and prone to wearing out. To diagnose the issue, you need to open the projector. Then you can e.g. place a finger on the fan case to feel it vibrate. Excessive vibration or noise means the fan is worn out and has to be replaced.
