在对I~2C总线控制的彩电进行数据调整时,有的机型需要专用的工厂遥控器才能进行调整,而大部分检修人员均没有专用遥控器,经过一些实践笔者发现有些机型用户遥控器稍作改动就能成为专用工厂遥控器,现分述如下: 1.长虹红双喜R2113T彩电遥控器的改动用型号为KIIB的用户遥控器去掉内部的二极管V3,用三只二极管(1N4148)正端接V3正端,负端分别接在集成电路(YC9028F—022)⑥、⑦、(12)脚,改动完
In the I ~ 2C bus control color TV data adjustment, and some models require a dedicated factory remote control can be adjusted, while most of the maintenance staff are not dedicated remote control, after some practice I found that some models of users remote control A little change can be a dedicated factory remote control, are as follows: 1. Changhong Double Happiness R2113T color TV remote control changes with the model for KIIB user remote control to remove the internal diode V3, with three diodes (1N4148) is the termination V3 positive terminal, negative terminal respectively connected to the integrated circuit (YC9028F-022) ⑥, ⑦, (12) feet, change finished
