. 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).
