现象:一台NV-G33EN录像机,在带盒装入机内后,发生主导轴电机时转时不转的故障。当将带盒插入带仓时,有时主导轴电机也能动作,将带盒自动吸入带仓,并将磁带加载至半加载状态。若进行放像,一开始能得到清晰的图像和闻有伴音节目,过不多久,伴音声变调,变尖细或高吭了,再一会即自动保护停机。如果此时重按VTR开关,能听到螺线管吸合一下就马上断开,继而又吸上,但电机不转。此时,主电源能送出5V与12V电压,VTR指示灯也亮,但过十秒
Phenomenon: A NV-G33EN video recorder, with the cassette into the machine, the spindle motor occurs when the turn does not turn the fault. When the cassette is inserted into the cassette holder, the capstan motor may sometimes be actuated to automatically draw the cassette into the cassette holder and load the cassette to a semi-loaded state. If you play a video, the beginning can get a clear picture and smell audio programs, after a while, accompanied by sound changes, tapering or high hang, and then automatically protect the shutdown. If you press the VTR switch at this time, you can hear the solenoid pull it off immediately, and then suction, but the motor does not turn. At this point, the main power can send 5V and 12V voltage, VTR indicator light, but over ten seconds
