If your technician does not know the Viking, I would not take it there. If you are close to a Joann Store, they are usually a Viking dealer. The turnaround time could depend upon when their technician is in. Otherwise, if it is running ok, like Tartan said, give it a thorough cleaning, put a drop of oil on the hook, and maybe just a drop on the shaft. It should be ok. If you put a drop of oil on the shaft be sure to sew for a few minutes on a scrap of fabric. Good luck and don't fret
