Question about Hitachi CP-S240 Multimedia Projector
After 15 minutes from switching the projector on a massege is displyed saying check the air flow, 2 minutes latter the projector turn itself off. I checked and cleaned the air filter then through the menu i resat the filter to 0 The projector is about 11 months old and is used once aweek inChurch for about 2 to 3 hours. I stoped useing it for now till the problem solved to avoide irrversable damage
With most projectors there is a foam air filter behind a grill that is the opening to the cooling channels. A fan ensures air flow to cool the lamp, etc. This filter prevents dust from gumming up the works (and depending on design) may prevent dust getting into the optics. As the filter gets dirty it gradually cuts off the air and at some point a protective circuit kicks in and turns off the lamp.
If the projector is on you will feel a stream of hot air coming out of the exit vent. Projectors vary in terms of amount of air flow, so its difficult to define what is normal for a specific model. However, you can simply hold a hand in front of the vent and see if there is air flow (It will be hot air so, careful). If there is a "good" stream of air things are fine, but if only a very light flow is felt the filter may be dirty.
If the filter has not been cleaned or replaced recently make sure the projector is turned off and cooled down then take off the inlet cover and remove the filter. Clean or replace per the instructions for the projector (and periodically as defined .. but taking into account the operating conditions). Once cleaned turn on the projector and feel the "normal" air current for future reference.
Heat is one of the major causes of projector failure, so make sure cooling vents (inlet and outlet) are not obstructed and filters are kept clean
