Three Examples in the Overhaul of Failures of TCL colour TV set

This essay introduces three examples in the overhaul of failures applied in the large-screen color television whose type is TCL9529. Then this paper analyses the reasons for failures in the light of relevant circuit principle and summarizes the maintenance of failures. "Overhaul of Failures" clarifies the process of analysis, judgment, examination and repair in seeking out faults; "Analysis of Failures" analyses all the faults one after another and assays such problems comparatively on the basis of brief illustration of circuit principle, so that the root cause of faults can be understood; "Summary of Overhaul" gives a summary in a broad outline from mehods and experiences of maintenance, thereby provides valuable experiences which can be drawn on by technicians who analyze, examine and repair similar failures.
