My S7 edge got water damaged and I took it apart to see the motherboard, the transistor or whatever it is towards the right of the big rectangular silver 5G WiFi module seems to be have become corroded and a bit black in colour ,I submerged the motherboard in 99% isopropyl alcohol and dryed it completely but it doesn't work. can I replace the couple of transistors that have corroded ? If so can anyone please guide me and let me know what's the exact transistor part that's damaged like it's name or series number? And where can I get it?
