Bulb life on projectors
Click on this icon for movies Please read all directions carefully Mistakes? We can't fix them if you don't let us know
           

Description:
On some of the district's projectors there are indicators that the bulb is about to have to be replaced

 

 
     
All of the Sharp projectors that we have in the district have a special feature. 

When the projector bulb has reached 5% life, they will

  • automatically display “Change the Lamp” on the screen,
  • the lamp indicator light on the projector panel will go yellow,
When the light goes yellow, submit a work order with
  • the room number
    (or cart number if it is on a cart), and
  • indicate that the bulb life warning light is on. 

The Tech Dept will work with your building to ensure a bulb is ordered and/or in stock. 

Although 5% life is approximately 200 more hours, do not wait to submit the work order so that the bulbs can be ordered if necessary and the replacement can be scheduled to avoid interruption of classroom instruction.
 

If this goes ignored and the bulb life reaches 0%,

  • the projector will go into Standby Mode and
     

  • the lamp indicator light on the projector panel will go red and look like the diagram to the right

Important Note!

 

If you attempt to turn on the projector, the bulb will not turn on and the projector will stay in Standby mode.

If you try to turn on the projector a fourth time without replacing the lamp, the projector will not turn on, and it will appear that the projector is broken.

If you experience this or see the panel as displayed, submit a work order and we will work to replace the bulb as quickly as possible.
