贵刊1996年第9期介绍的在三洋83P机心彩电上加装AV插口的方法,虽然较以往一些报刊上介绍的方法简单,但我认为仍有可改进之处。这里介绍一种只用四只元件和一副莲花插座即可使彩电增加AV插口的方法。 改装部分见附图:其中S为小型拨动开关或小钮子开关。RP为一般小型电位器。C是普通电解电容。R是1/4W电阻。具体改装方法如下:(1)在电视机适当位置将插座、电位器和开关固定好。由于该机心属“冷”底盘,因此使得安装变得极为简便。电容电阻直接焊在开关和电位器上。(2)在电视机底板上找到跳接线J15,该跳接线为机内音频信号通路线,将其焊开,用屏蔽线按图接好。(3)继续找到跳接线J31,该跳接线是机内视频信号通路线,将其焊开,用75Ω细
The ninth edition of 1996, introduced in the Sanyo 83P telematics on the installation of AV jack method, although some of the methods introduced in the past than simple, but I think there are still improvements. Here to introduce a way to use only four components and a lotus socket can make color TV AV jack. Refit some see photos: Where S is a small toggle switch or a small button switch. RP for the general small potentiometer. C is a common electrolytic capacitor. R is a 1 / 4W resistor. Specific modification methods are as follows: (1) the appropriate position in the TV socket, potentiometer and switch fixed. Because the machine is a “cold” chassis, it makes installation extremely easy. Capacitor resistance directly on the switch and potentiometer. (2) Find the jumper J15 on the TV backplane. The jumper is the audio signal path inside the machine. (3) continue to find the jumper J31, the jumper is the video signal line within the machine, the welding open, with 75Ω fine
