Why won't my Singer Touch Tronic pick up the bobbin thread? ?

Singer Touch Tronic 2010, had been serviced, and was sewing fine. Now it will not pick up the bobbin thread. New needle did not help. What is the problem?

Have you tried a new bobbin? If you have a plastic bobbin, they get nicks sometimes and don't perform as well. Otherwise I'd also try cleaning out the bobbin case. Make sure your new needle is seated correctly as well.
