| 空调不开机，不开机主要有2种，第一就是上电没有任何反应，【变压器，保险管，整流桥】这些应该是小儿科的事情，重要的测量5V等电压都正常这种问题大部分换晶振【就在CPU旁边的】可以解决。还有一种是插电有蜂鸣声，遥控不开机【手动可以】基本就是接收头坏【换接收头不会再网上搜下就知道，找接收板的地脚很容易吧，电容的负极或者电路板很宽的那条线，找到地脚其他两脚就很容易哦】 There are two main types of air conditioners that do not start up. The first one is that there is no response when the air conditioner is powered on. [transformer, fuse, rectifier bridge] these should be a matter for pediatrics. The important measurement voltage such as 5V is normal. Most of these problems can be solved by the crystal oscillator [next to the CPU]. The other is that there is a beep when the power is plugged in and the remote control is not turned on [manual operation can be performed] basically, the receiver head is broken [you will not search the Internet after changing the receiver head. It is easy to find the foundation of the receiver board. It is easy to find the negative pole of the capacitor or the line with a wide circuit board. It is easy to find the other two feet of the foundation] 2、空调不定时自动开关机，有的半夜叫，清洗接收板，换接收头或者拿掉自动转换开关基本可以通杀 2. The air conditioner switches on and off automatically from time to time. Some people call in the middle of the night. Cleaning the receiver board, changing the receiver head or removing the automatic transfer switch can basically kill people |
