We've had a rash of Berninas with dead power circuit boards. And the one thing they all had in common was they hadn't been used for 9 months to 3 years. These have all been Bernina 220 or 230 models that are about 8 to 10 years old. That's interesting what Tom W said about taking 20 minutes to turn on. I'll have to try that on the next one that comes into the shop.
