Reset Lamp Hours

This is an important final step when changing your lamp, if you do not reset the DLP lamp timer your projector may stop working when the time expires. This article provides details on how to perform the reset and why it is important.

The reason why is that many modern projectors and TVs provide internal monitoring of the bulb, often called a dlp lamp timer. Some equipment will shut down when the programed lamp limit is reached. This normally results in the TV or projector not starting up at all, even if the bulb is replaced. However the fix is easy, a simple reset is necessary. Keep in mind that the projector has no idea when you changed the bulb, or even if you placed a new bulb in the unit, therefore the hours are counted against the expected bulb life from the last time you reset it.
