A hair dryer will usually free up the coils but don't get it too hot of course. How sharp is the picture? HOT cathode current? Is the flyback hot? If all that is ok I'd leave it but that's just my opinion and I am not an expert. 19 Kv is about normal for the 5. I see an F104 in my 1955-66 RCA Field Service Guide, it is a push and twist to remove.
