PROBLEM TO BE SOLVED: To inhibit a protective function from operating only in a manufacturing line. SOLUTION: A microcomputer 4 inhibits a protective function by detecting the voltage level of an adjusting jig 20 connected to a terminal t4 for adjustment, before an abnormality-detecting control for detecting abnormalities in horizontal and vertical deflection circuit systems begins to operate. This design causes no erroneous interrupt of a main power supply voltage in the adjusting processes of a manufacturing line, and as a result enables to perform various adjustment easily. |
