I don't have a bernina.. but on my Janome... I have to "tell" it what size I'm using by selecting it from the menu.

THEN CONTACT BERNINA WE HAVE NO FIXES FOR THAT PROBLEM

Needle position servo... see video for similar issue.

The problem is that of a stuck piston detent on the pattern selector support that snaps the top cover closed.

1. Open the light cover
2. Apply pressure with thumbs on the bottom edge of the top cover on both the right and left sides of the cover. The cover should pop up...Too much pressure on the left side, (if this thing is really stuck) and you might break the top cover at the thread tension slot. Be careful here....
   
3. Add a drop of acetone (fingernail polish remover) to the piston detent and work it free by pushing it back and forth. Avoid getting any acetone on the painted surfaces of the machine.
   
4. Continue to work free, repeating with a few drops of acetone, and wipe clean. Don't oil this part. It was a petroleum product combined with a galvanic process (aluminum and steel) that caused the problem in the first place, not to mention age.
5. Use DTE Heavy Medium oil rather than a white or clear oil when you lubricate your machine. White oils are unstable and will oxidize (decay) much more quickly. Also avoid 3 in 1 oil and stuff like WD40....very bad....
   
6. Oil 1/2 a drop on those prescribed areas. Too much oil is more harmful than not enough....
7. Contact your Bernina dealer for this oil.
   

you may have to replace the upper thread sensor

try manuals.lib.com. I have had great luck getting older model sewing machine manuals from them. I also bought a featherweight service and repair manual on ebay; well worth the money.

Calibrate the diplay The Display calibration can be opened as follows: - turn off the sewing-/embroidery computer - touch the two needle positioning buttons on the front panel and keep them pressed - turn on the sewing-/embroidery computer and release the buttons as soon as the Display appears - touch the calibration icon - touch the center of the cross using the touch pen -- the cross moves to the next position - repeat this until all three positions shown are calibrated -- the Display is closed -- the adjustment is saved

Basically it is a matter of a stuck part. Flip open the top by prying up on the front or ends of the lid. You already noticed the hinges on the back. When you get it open, exercise the right hand lever on top (marked ZZ at bottom and 1-20 at top. If you look just to the right of this lever against the back wall you will see that it moves a little part back and forth into triangle shaped grooves. The part is not going completely into the grooves so drop some oil in there and exercise it a few more times, using your fingers if necessary to make the part move into the triangle grooves at the front and back. After a while it will loosen up where it should operate by itself smoothly . Hope this helps, I know it will.

Try the following video. It's not the exact model but the bobbin/hook assembly should be close enough.

If the machine won't power up its most likely a problem with the power board inside of the machine. I have replaced a bunch of bad power boards on the 600 and 400 series Berninas over the years. The 600 and 400 series machines use the same board. I service and sell lightly used Berninas on eBay under the user name bushvideo.
