Hi, Mike,
I know opinions on recapping can differ, so there's two times "maybe". In all cases it can't be a mistake to check how they look.
I have included PSU problem, because wrong voltages are often a possible source of wrong function, and electrolytic caps are first to be suspected. Not just my experience :-)

- maybe change electrolytic caps in PSU, after so many years maybe they need to be replacedNO NO NO. Electrolytic capacitors from 1989 are going to be OK. Statistically, they're OK. The chances of a electro cap from 1989 being bad are very LOW. And the symptoms of the problem don't remotely sound like a electro cap problem.Everything else is good advice. :-)/Mike
