I accidentally plugged my singer 7258 computerized sewing machine into a 240v plug and something inside blew up. The repair guy says he doesn't have spares to fix it. Any help on where I can order spare parts from for my machine?

Certified Viking parts are only available from an authorized Husqvarna Viking dealer. However, there are some third party parts companies online. You should be able to find these using Google Search. However, I strongly recommend you have the machine serviced through an authorized Husqvarna Viking dealer. You can find the nearest dealer by click on the "Dealer" link at http://www.husqvarnaviking.com
Good luck.

SOURCE: Singer 7258 will not sew automatic buttonholes. The needle goes up and down, but that's all. The buttonhole lever is down, so that's not it. Please help.

if the sewing machine is set on the buttonhole setting then it's
possible that the sewing machine motherboard has a problem.
or a part could be damaged, the machine may need some type
of adjustment.
