How can I fix my Shark Intelli-Sew 9110 Sewing Machine?

Ouch difficult to pinpoint problem without knowing history on machine , when last was it serviced,any previous problems with stitches not working. sometimes it could be as simple as a good clean and oil but on fully electronic models all stepper motors need to be properly maintained to ensure good working. suggets take it to good techno just for better look at machine
