康佳T5428D型彩电是一种比较新型的彩电,其微处理器采用ST6367,中放与解码电路采用三洋公司的LA7688N,场输出电路采用LA7837,整机设计紧凑而合理,故在市场上拥有量颇大,那么此类彩电能否加装股票图文板呢?答案是肯定的,我采用百思特电子科技有限公司出品的BST9804型图文板进行加装,具体如下: 1.康佳T5428D型彩电的微处理器N601采用ST6367,其遥控指令系统属非飞利浦格式,故图文板Z4的遥控信号线采取并接方式,即Z4的RI并在R649的一端。 2.康佳T5428D型彩电的中放及解码电路均合二为一采用LA7688N,该芯片的⑧脚输出负极性的视频信号,故图文板Z2的VI可在Z102的后级取,并就近接数字屏蔽地线。 3.康佳T5428D型彩电的场输出电路采用
Konka T5428D-type TV is a relatively new type of color TV, the microprocessor uses ST6367, put in and decode circuit Sanyo’s LA7688N, field output circuit using LA7837, the whole compact and reasonable design, it has the volume on the market quite Big, so this kind of color TV can install stock graphic board? The answer is yes, I use Best Electronic Technology Co., Ltd. produced BST9804 type graphic board for retrofitting, as follows: 1. Konka T5428D type TV Microprocessor N601 using ST6367, the remote command system is non-Philips format, so the graphic board Z4 remote control signal line to take the parallel mode, that is, Z4 RI and one end of the R649. 2. Konka T5428D-type TV in the release and decoding circuits are combined with one for the use of LA7688N, ⑧ pin of the chip output negative polarity video signal, so the graphic board Z2 VI can be taken in the Z102 after the level, and the nearest Digital shield ground. 3. Konka T5428D color TV field output circuit used
