S20 FE Drops Celluar to "no radio"

Hi,

I have a S20 FE that i have changed display after drop. Everything works great except the the celluar dont work sometimes. I can have full 4G and then it drops to a stop sign and says “no radio” in settings.

Have changed the Charging/antenna board without any luck. Also looked for physical damage on motherboard to find something to resolder.

Any ideas what i can do? I have the knowledge of microsoldering.
