Question about Hitachi CP-S240 Multimedia Projector
This means you may have an obstruction preventing airflow from circulating properly. If this is the case, it can lead to overheating of the projector, which could result in very expensive repairs.
You need to regularly clean the air filter and rest the filter timer to ensure that your projector can cool itself properly. I recommend doing this every 100 hours of use. In fact, Hitachi projectors can be set to warn you when a certain amount of time has elapsed. I believe 100 hours is the default.
If cleaning the air filter and resetting the filter timer does not remedy this, you can use canned air to blow out the inside of the projector and try to clear the obstruction.
You also want to make sure all fans on your projector are working. If not, stop using the projector and replace those as soon as possible.
Overheating is the leading cause of projector malfunction, and basic routine maintenace can increase the life of your projector and the lamp by a great deal. For example, the lamps for that machine are typically estimated to have a life of no greater than 2000 hours, and typically you'll see them go out anywhere from 1300 hours to 1600 hours. Because I regularly check my machines, the ones that are not used intensively for hours on end every day will often have a lamp life of over 2000 hours, and I found one recently that made it to 3100 hours.
