I bought my 930 fifteen years ago as a backup to my 1530. I paid more than $700. It had problems last year and the repair cost way more $275 from a Bernina dealer.
The 1530 broke down too and went to Bernina in Illinois for repair. As my dealer says, if it's broke, it can be fixed. And so can yours. It happens.
By the way, do you use a surge protector?
IMHO, absolutely, you should get it fixed.
