This page covers data projectors.

Summary

Data projectors are often quite expensive items and so well worth fixing when they go wrong. With care, disassembly and fixing are not generally too difficult, but an understanding of their principles will help.

Safety

Projector lamps get extremely hot. Always leave a projector to cool down for 30 - 45 minutes before working on it, so as to avoid the risk of burns.

Take great care not to touch any of the glass of a projector lamp as finger grease can shorten its life, and in the worst case, cause it to explode.
