@fredo24477 without actually seeing this "black dot" and only going by your description, this sounds like its time to clean the CCD sensor.

Look around page 60 for the CCD and how to get to it etc. Also, check [https://www.thephotoforum.com/threads/cant-find-the-sensor-cleaning-mode-on-my-d50.78332/|this site] about the self cleaning function on your D50
