Projectorswarning light for promethean projector model PRM 20

If the projector’s lamp is not lighting when the projector starts up, then one thing we would recommend trying would be to borrow a working lamp from another PRM-20 projector (or a spare lamp for that projector you may have on-hand) and install that in this unit.

If the projector will not light the lamp at that point and presents the same LED behavior when trying to start up, please contact us for further instructions.
