Audio output to the Audio board. isplaying your vision! Easy maintenance of Plasma Display Basic operation of Plasma Display 1. After turning on power switch, power board sends Vsby +5V Volt to Micro Processor IC waiting for ON signals from Key Switch or Remote Receiver. 2. When the ON signal from Key Switch or Remote Receiver is detectedMicro Processor will send ON Control signals to Power. Then Power sends volts(VsVxg VwVfVddVcc and +9V)to PCBs working. This time VIF will send signals to display back light OSD on the panel and start to search available signal sources. If the audio signals inputthem will be amplified by Audio AMP and transmitted to Speakers. 3. If some abnormal signals are detectedfor example:over voltsover currentover temperature and under voltsthe system will be shut down by Power off. isplaying your vision!
