TC—29GF70R是日本松下公司生产的74cm(29英寸)大屏幕多制式彩色电视机。该彩电虽然附有电路原理图,但图纸上所标的电压参数不全,又和实际电压有较大的出入,因此,笔者将一台正常工作的该型号彩电所有集成电路的静态工作电压和断电后在路正、反向电阻测量下来并列成表1~26所示,以供广大的维修人员作参考。注:(1)表格中的测试数据均用南京电表厂生产的
The TC-29GF70R is a 74cm (29 ") large screen multi-format color television manufactured by Panasonic Corporation of Japan. Although the color TV with circuit schematics, but the drawings on the voltage parameter is incomplete, and the actual voltage has a greater discrepancy, so I will be a normal job of the model color TV all the static working voltage and power supply After the road is, the measured reverse resistance and tied into a table shown in Table 1 ~ 26, for the majority of maintenance personnel for reference. Note: (1) The test data in the table are all produced by Nanjing Meter Factory
