Question about Bernina Sewing Machines
This is a problem with the particular model. Bernina has a servi ce bulletin out on that issue and it should be under warranty. It needs a new power supply, or L-Print as Bernina calls it.

You correctly surmise it is a problem on the power supply board in the back cover - called an 'L'-print. You can change this for around £150 or, if you have some electronic knowledge, you can do the job much cheaper by identifying the 8-pin DIL chip nearest the multiway connector - it is labelled KA34063 - change this for a new one and it will cure the problem. Parts can be found on eBay for under £5.
