It seems to be a water damaged Mac from the issues described. Hard to tell exactly what needs to be replaced but we talk about a component level issue that’s not a DIY repair. For a non technician it would require purchase of quite a bit of tools, skills and weeks of study of schematics to get a clue on what may be wrong. All in all, a logic board replacement or a microsoldering pro would be needed to get the Mac back in working order.
