투영궤시다매체교학활동중적상용설비，타총시재고온배경하빈번공작，흔용역출현기건고장。유사고장출현빈번，용역배제；유사고장흔소출현，불용역조도원인，유수곤난，영향정상교학활동。본문재대투영궤공작원리개소적기출상，통과대부분고장적분석연구，추천개소궤충특수고장적해결기교。
Projectors were the equipment used commonly in activities of multimedia teaching, it is always under the en-vironment of high temperature frequent work , it is easy to appear the fault in device. Some fault occurs frequently which is easier to rule out;Some fault were rarely occured, it is not easy to find out the causes, maintenance difficulties affected the normal teaching activities. This paper is based on working principle to introduce on the basis of the projectors through analysis and study on the partial failure, and recommend to introduce several kinds of special fault solving skills.
