第四讲节能控制电路分析与维修一、节能控制电路分析节能控制电路主要功能是:当用户开机时间较长[一般20 min(分钟)以上]而不输入信号时,显示器会自动转入节电状态,屏幕上无任何显示(也可自行设定一个图案)从而达到节电目的。节能腔制电路是根据行同步、场同步信号的有无来确定机器是否进入节电状态的,根据美国环保署颁布的“能源 Analysis of energy-saving control circuit analysis and maintenance First, the energy-saving control circuit analysis The main functions of energy-saving control circuit is: When the user boot longer [generally 20 min (minutes)] without input signal, the monitor will automatically switch to saving State, no display on the screen (you can also set a pattern) to achieve the purpose of saving. Energy-saving cavity circuit is based on line synchronization, field synchronization signal to determine whether the machine enters the power-saving state, according to the United States Environmental Protection Agency promulgated the ”Energy
