To set the Philips TV model 40PFS6009/12 so that it always starts with the last input source used, follow these steps:

1. call up the home screen: Press the "Home" button on the remote control to get to the home screen.
2. open settings: Navigate to the right with the thumb pad and highlight the user profile icon. Then select "Settings" from the menu.
3. system settings: In the settings menu, navigate down to "System" and press "OK".
4. Power & Energy: Select "Power & Energy" and press "OK".
5. power on behaviour: Select "Power on behavior" and press "OK". Here you will find the options "Google TV Home Screen" or "Last Input Used".
6. select last input source: Select "Last Input Used" and confirm with "OK".

This ensures that the TV always starts with the last input source used (e.g. HDMI 1) instead of landing on the home screen.
