采用168P-P46TTS-02电源板创维液晶彩电三无
  发生开机三无,待机指示灯亮故障,多为主电源故障引起。二次开机后,测量ON/OFF是否为高电平,如果为高电平,首先测量PFC电路提供的+390V供电和IC601的12脚VCC2供电,如果390V供电仅为300V,则是PFC电路未工作;无VCC2供电,查开关机控制电路QSO1、光耦合器P02,QP10组成的VCC控制电路和QP09,DP14组成的稳压电路。上述供电正常,再查主电源IC601及其外部电路元器件。
  
  如果PFC电路未工作,首先检修市电整流滤波后的+300V脉动电压,IC600的19脚VCC1供电,再查IC600及其外部电路
