It is very common for the switches on receivers like this to have some corrosion. This could easily be why the FM isn't working. They do not need to be replaced! You can clean them using Deoxit (with the green highlights on the spray can) in a spray can.
If you don't have technical experience, have someone who does do this. You can make a mess of things otherwise- I've seen it!
It may be that the unit has more problems than just dirty controls and switches. But that's where you start and in most cases with a unit this old, that's all it needs.
