Unfortunately, we cannot obtain the required power supply unit. Unfortunately, the supplier no longer offers this spare part either.
However, we are still trying to find out whether a suitable alternative is available from the manufacturer.

We have now received feedback that a suitable replacement part can be ordered from Philips itself. Unfortunately, I cannot link this here.
The matching power supply could be found with CP0925 from the manufacturer itself.
I apologise for the long waiting time.

Embarrassing, Philips!
