Default input at power-on is "analogue TV" how to change it? [26PF5521D]

[zaphod]

Our TV is a 26PF5521D software ldtvZapper_HW260.256_SW2.0.38
It usually comes back on in the same mode that it was switched off in.
But we mostly use it in EXT1 (SCART from a Humax box). If the Humax is off when the TV is next switched back on, the TV can't find a signal on EXT1 so selects analogue TV instead. Since the switch-off that's a blue screen. Digital would be a much preferable default.
The manual clearly states on page 7:

When the television is powered on for the first time, it will always be in DIGITAL mode.

Perhaps a random button-press sequence at some time has changed this - is there a way to change the default selection back to DIGITAL TV?
Or even, perhaps a software update giving the option to disable the analogue tuner altogether?
Thanks, Ed.

Hi

Press and Hold the menu Button on the Front-Panel.
The TV should start with the Initial Setup, after that it should be like it was supposed to be.
