Basic operation of Plasma Display
1. After turning on power switch, power board sends 5Vst-by Volt to Micro Processor
2. The micro Processor memorize the last state of Power, When the last state of
power is on or receive power on signal from local Key or Remote control, Micro
Processor will send on control signal to power. Then Power sends (5Vsc, 9Vsc,
24V and RLYON, Vs ON) to PCBs working. This time VIF will send signals to
display Image, OSD on the panel and start to search available signal sources.
If the audio signals input, them will be amplified by Audio AMP and transmitted to
Speakers.
3. If some abnormal signals are detected (for example: over volts, over current, over
temperature and under volts), the system will be shut down by Power off.
