I have the same problem. I bought it used and after a few days it developed the exact same issue. It does seem like it might be a software problem since it developed spontaneously. Maybe some internal component, but hopefully there is a software fix. Based on this forum this seems to be a not infrequent problem, so I'm sure someone will have looked into this. Has anyone found a fix for this. I don't think I can get a support ticket or service, since I am not the original owner (I got it through FB marketplace) but any help or ideas would be greatly appreciated. Thank you.
