Apart from the usual used LCD projectors, those which have been used from some considerable amount of time by someone and are now for sale, there are some other categories of used LCD Projectors.

One of these categories is called demo projectors - projectors that have been used sparingly in-house for customer demonstrations. The majority of demo projectors generally have 90% or more of the original lamp life remaining at the time of resale. Demo models that are still in production ship with a full manufacturer’s warranty. The length of warranty varies on demo models that are no longer in production.

Some may still see these relics of the projection world in old sport bars, quite possibly displaying a very bad picture and very pink looking whites. The reason for this is quite simple, that projector has likely been their for 15+ years chugging away day in day out without once having its tubes changed. If someone was to change the tubes in these old beasts they spring back to life with a good tune up and are as good as brand new.
