一、遥控信号接收组件中BX1323的代换索尼KV—2092CH型遥控彩色电视机,使用的红外遥控信号接收组件H1是由BX1323及其相关的电路组成。该组件是一块厚膜组件,无法测量其中的 BX1323各脚电压,外围元件也不太容易拆下来检查其好坏。 H1组件内电路结构如图1所示,当该组件损坏以后可采用以下两种方法之一对其进行代换。
First, the remote control signal receiving component BX1323 substitution Sony KV-2092CH remote color TV, the use of infrared remote control signal receiving component H1 is composed of BX1323 and its related circuits. The component is a thick film component, can not measure the voltage of each foot of BX1323 among them, the peripheral component is also not easy to dismantle and check its good or bad. H1 circuit components within the structure shown in Figure 1, when the component is damaged after the adoption of one of the following two methods to replace them.
