Please help

I have the Jenome 6500 Memory Craft.
It started to have issues with the bobbin popping up and or making noise when sewing.
I have attached a video without thread in it and it still does this.
Things I have done.
1. Validated that bobbin is in correctly. 
2. Used a new bobbin.
3. Reused the current bobbin, but rethreaded. 
4. Adjusted the top tension
5. Taken apart and cleaned.
6. Repeated steps above.
Video attached 
Please advise, thank you so very much.
