The electronic technology workshop practice in technical colleges in Nigeria has overtime been dominated with the teaching of practical skills in radio and television that are gradually phasing away in the electronic world, hence the need to upgrade it by integrating the practical contents of modern digital electronics, of which DVD home theatre sound system is one of the electronic gadgets. This study therefore determined the corrective maintenance skills requirements in DVD home theatre sound system necessary for improving the workshop practice of electronic technology via curriculum innovation in technical colleges. Three research questions were raised and answered using mean statistic, while one hypothesis was formulated and tested using t-test statistic. The descriptive survey research design was employed in the study. A five point scaled questionnaire was the instrument used for data collection. The sample size was 164, comprising electronic technology teachers in universities and technical colleges and DVD home theatre sound system technicians in Edo State. The instrument was validated by experts and its reliability coefficient obtained using Cronbach’s alpha formula was 0.876. It was found that the corrective maintenance skills requirements in DVD home theatre sound system necessary for integration into technical college curriculum for electronic technology workshop practice are skills in the use of tools and equipment to perform such maintenance, fault diagnosis skills in order to carry out the maintenance and the actual repairs (corrective maintenance) skills. It was therefore recommended that electronic technology teachers should be trained in the teaching of practical skills in maintenance of DVD home theatre sound system for capacity building. Key words: DVD home theatre sound system, corrective maintenance, curriculum, electronic technology, technical college.
