一台松下NV—G33录像机多功能显示屏有数字闪烁,但无法装入带盒。分析:该机装带动作由主导轴电机完成,插入带盒时,带盒状态检测开关输出一高电平至IC_(6001)(23)脚,且从(43)脚输出高电平至IC_(2102)(23)脚,IC_(2102)⑩脚便输出低电平至IC_(2501)(11)脚,从而IC_(2501)便驱动主导轴电机正转,吸入带盒。检修:打开机壳,仔细观察机械部分未发现有卡死现象。测IC_(2102)(MN15312VPL)⑩脚电压,3V左右,插
A Panasonic NV-G33 VCR multi-function display with digital flashing, but can not be loaded with a cassette. Analysis: This machine is installed by the capstan motor to complete the action, insert the cassette, the cassette status switch detects a high output to IC_ (6001) (23) feet, and from (43) feet high output to IC_ (2102) (23) feet, IC_ (2102) ⑩ feet will output low to IC_ (2501) (11) feet, so IC_ (2501) will drive the capstan motor forward, suction cartridge. Maintenance: Open the case, carefully observe the mechanical part did not find a stuck phenomenon. IC_ (2102) (MN15312VPL) ⑩ foot voltage, 3V or so, plug
