PlanoSpot 7TC turns off after 17 seconds

Hello,
I am trying to repair two PlanoSpot 7TC (LED Flood lightS).

They work fine for 17 secs them they turn off the light.

When the light turns off then the small display and the LEDs stay on.

It is then possible to select another program and the light will turn on for another 17 secs and so on.

Both fuses seems to be fine.

Any tips on where to look?

Best regards,
Martin
