I am new to the forum, but 'reaching out' to you experts for some help - please!
I have a Husqvarna / Viking 6690 computerised sewing machine that has 3 different circuit boards - all of which are not operating well - and only allow a bit of straight sewing.
Does anybody have any experience with replacement / repair of these machine parts?
It is a beautiful machine - and the reason to consider repair.
Thanks a lot for the fast response - and for those two manuals! Much appreciated. Mechanically, the machine is okay, its just that the circuit boards dot all work - and I am wondering if there are any spares around. I did have a couple of blown capacitors replaced which allows for straight stitching, but the cassette board is not working. Thanks again!
