My Baby Lock is seven or eight years old. Never had a tune up or problem with it. I love it. For some reason, I decide that I should take it in for a tune up. It's a minimum of $70.00. Took it in on Tuesday and begged for fast service. Got it back yesterday for $108.00. The bobbin case needed replacing. It sews and sounds wonderful. But, now the screen ony lights up half way. Didn't have that problem before I took it in. I called and he said it was probably a wire loose. I have to take it back again, 40 miles one way.
When you take your machine for service, ask that it be plugged in and take a few stitches before leaving the shop. If I would have done that, I would have immediately noticed the light not working properly.
