一、概述:该机为14英寸小台式彩电,全塑机壳,采用370BHB 22自会聚彩显管,为日本75年产NTSC-M制,原在日本本国使用。机内通道、伴音、色解码均采用集成电路,行帧扫描部份也比较简单,如行扫描一共只用了3只晶体管,三墓色视放输出调阴式,易于与TA7193解码块接口,显象管可与我国咸阳产彩虹牌14英寸管互换,这种机型在日本,尤其是三菱产品中有一定的代表性。80年以后日本产品除将扫描部份集成化及电源改成开关电源外,其他部份都与该机电路程式相近。今后数年,我国从国外流入的NTSC制彩电也都将 First, an overview: This machine is a small desktop 14-inch color TV, all-plastic chassis, using self-convergence 370BHB 22 color tube, Japan’s NTSC-M system with 75 years of production, the original use in Japan. Machine channel, audio, color decoding are integrated circuits, the line frame scanning part is relatively simple, such as line scan a total of only three transistors, three tomb color as the output output tone style, easy to interface with the TA7193 decoding block, CRT with Xianyang in China produced 14-inch rainbow tube interchangeable, this model in Japan, especially Mitsubishi products have a certain representation. 80 years later Japanese products in addition to the scanning part of the integration and power into a switching power supply, the other parts are similar to the mechanical and electrical programs. In the next few years, NTSC color TV sets that China has inflows from abroad will also be handed over
