Otherwise I may need to exchange the whole board (Silga T120 C 94V0) I assume. But do not have any idea where to get it from.
Many thanks for any advice!

hello
these is crystal diode (germanium) check the image probably all 4 with same measurement.. (i presume )
If you have multimeter , desolder all 4 select diode modality and make the measurement ..if 1 or more is with different value replace.
