Abstract

The study was carried out to determine precautionary measures necessary in liquid crystal display (LCD) television maintenance by electronic technician. The population for the study was 3209 consisting of 11 electronic teachers and 3198 electronic technicians. 11 electronic teachers and 155 electronic technicians selected by simple random sampling were used for the study. Questionnaire consisting of 57 items was used to elicit responses from electronic teachers and electronic technicians regarding the two research questions. Data collected were analyzed using mean while t-test for independent sample was used to test the two null hypotheses at 0.05 level of significance. Analysis revealed the important components of LCD television that may occasionally developed faults and important precautionary measures that should be taken in LCD television maintenance. It was concluded that electronic technicians should carry out maintenance of LCD televisions by observing the precautionary measures to be taken in maintenance of LCD televisions.
