Why is your projector not working?

Many schools installed Interactive whiteboards and projectors over the last  few  years but at this stage, warranties are starting to run out and, inevitably, that’s when things start to go wrong.  In order to minimise major breakdowns, it is recommended to treat a projector like a car – it needs a bit of a service now and then!  The following suggestions have been recommended by Stephen Linnane from Liosdoire Computers who has been providing ICT equipment to schools for several years:
  • Remove & clean projector filters
  • Extract internal contamination from projector
  • Clean projector lens
  • Clean interactive whiteboard surface if present
  • Provide lamp life and projector condition information

Most of the above can be done by the classroom teacher by following instructions from the projector’s manual.  If the manual has been “filed away” never to be seen again, a Google search should provide tutorials on cleaning filters.

With regards to Interactive Whiteboard surfaces, it’s a good idea to make sure to use a spray or cleaner that won’t damage the surface.  There are plenty of these available on the market but do stay away from cleaners with bleach and corrosives.

By following simple health checks every few months you could find yourself with a projector lasting much longer, saving you a lot of money and hassle.
