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.
