It's certainly becoming more rare to find an opportunity to replace discrete components.
Back in the day (find an old tube type kitchen radio and look inside) you could see, feel and smell every component in a electronics box.
Not no mo'.
Board level replacement is the norm (sadly) but in the main it isn't generally worth it to try to fix them. Takes way too much time and it's very difficult to know if there isn't some other component that dead as well. And forget finding or creating a schematic to help with the diagnosis.
And, in your case, finding a replacement part.
Good luck.
