When using the ILS procedure, the pink diamond showing the ILS on the ADI and HSI are missing + the "needle" of the ILS stays on the left ! .

I did it like that :
- I entered the ILS frequency into the radio panel
- switched the HSI on ILS : I can see the the confirmation of the ILS frequency on the HSI
- selected the LOC + APP
- I could catch the ILS : G/S and LOC in green on the ADI
- LAND3 illuminated in green
- and kiss landed like in the manuals !

BUT ! no pink diamond + frozen ILS needle on the HSI !

What did i wrong ?

Thank's for the help
