. If the TV set was on normal run mode before switching off, the microcontroller delivers horizontal drive voltage at pin
24 and 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 (pin 1).
5-10-2 TV normal run and stand-by mode operations
Depending on remote control commands, I501 microcontroller part pin 1 (power) is set to :
- high for normal run mode
- low for stand-by mode
a) TV on normal run mode
* I501 microcontroller part pin 1 (power) effect
I501 microcontroller part pin 1 (power) is connected to the following circuit :
