Cleaning the Filter in your LCD player

When I use my Promethean Board, I kept getting a message about needing to clean my filter.  So, of course, I want to know how to clean my filter.  I kept asking the technology people who know that I always have at least one question.  Well, I finally wore Dave down so he decided to see how to clean the filter.  It's actually quite easy and doable.

1.  Find a chair to stand on.

2.  Locate the side of the LCD with a rectangle (it's the side opposite of the one with the round opening).  Here's Dave demonstrating:

3.  Push the tab to the left and remove the rectangular door.

4.  Pop out the filter located right inside the door.  Brush off and/or blow out the dust (a good amount of dust found its way into my filter).

5.  Put filter back in the LCD; put the rectangular door in place; and you're done.

Dave suggests cleaning the filter about twice a year. 

I bet my LCD feels cleaner and lighter now.
