If the TV set was on normal run mode before switching off, the microcontroller delivers horizontal drive
voltage at pin 24 picture appears on screen.
If the TV set was on stand-by mode before switching off, the microcontroller switches TV set to stand-
by mode, decreasing power pin voltage (pin5)
5-10-2 TV normal run and stand-by mode operations
Depending on remote control commands, I501 microcontroller part pin 5 (power) is set to :
- low for normal run mode.
- high for stand-by mode.
a) TV on normal run mode
* I501 microcontroller part pin 5 (power) effect
