PROBLEM TO BE SOLVED: To make the high density of parts by mounting a chassis on a circuit board to arrange a magnetic head near one side of a case, providing the vertical deflection driver, horizontal deflection driver for a television set, a high voltage output circuit and a power supply circuit within the same area on the same printed wiring circuit board and arranging the area near the other side of the case. SOLUTION: Mechanism parts for video such as a video head cylinder and a magnetic head are mounted on a chassis 15 for a video mechanism part mounting and a power supply circuit part is mounted on a power supply area 14A that is less than about 1/4 of a main circuit board. Electronic parts except a CRT electronic beam control circuit and a power supply circuit for a television set and electronic parts except a power supply circuit for a video device are mounted in one prescribed area 14B of about 3/4 of the residual area. The number of parts are reduced by sharing a low voltage power source for a television electronic device and a video electronic device and also a printed circuit is wired from the low voltage power source of the television and video electronic devices at the shortest distance. |
