Metz (Micos) TV IR Codes?

Manufacturer: Metz
Model: Micos

Good evening,
I am desperately trying to find IR codes for a Metz Micos (2021) TV set - especially Power on/off.
I was/am able to have the remote 3 “learn” a few of the codes but unfortunately whatever I try, fails with the Power on/off key/code.
Did anybody resolve this issue?

Have you tried the TV code set thats availble in the Global Caché databse?
