Hey I just replaced a bulb in my cp x345 and it worked fine for about a month and now it keeps powering off after like 5 minutes. It is mounted upside down on the roof... But when i take it down and set it on a table it works fine. There is adequate ventilation when it is upside down.

Most likely you have a defective lamp or it is near the end of its life. It's also possible that the high voltage power supply is going out. You might check the lamp hours - you can find this in the advanced menu. Also check the air filter, if you haven't cleaned it, the airflow might be restricted, shutting down the projector.
SOURCE: Machine powers down and no lamp.
one of the fans may not be working properly or the ballast is shot.
