Optoma projectors utilize a self-monitoring lamp timer, meaning that resetting the timer is part of the bulb replacement function. Optoma designed replacing the bulb to be a consumer-level process, not requiring a specialized technician to tackle the task. Given this, it is critical that you not ignore bulb replacement warnings. All that is required for replacing an Optoma lamp is a simple screwdriver and care in handling the bulb.
Turn off the power to the unit, either from the remote or front panel's "Power/Standby" button. Allow 30 minutes for the bulb and projector lamp housing to cool.
