SONY ICF-6700 desoldered 3 wires near ANT POINT

My Grandpa  had given this Set to me, when I was 5 standard as i love electronics and electricals from childhood. In 2018 it starts malfunctioning, So, I try servicing myself, by cleaning the PCB's with Ethyl Alcohol. as in my area there is no good mechanic who can repair this Radio( around 200 Km surrounding). I try with great care, Every step I use to note down in a paper. I also make video record by my old phone, but by mistake the phone was fallen down inside a bucket where water was there, but all of sudden I saw 3 wires out from there soldering points, near Ant Connection points. So please help me.
