Title
Bernina 350 PE L-Board D5 Capacitor Replacement
Introduction
For Bernina sewing machines that no longer turn on or the sewing machine takes 10 to 60 minutes for it's display and light to illuminate after turning the switch on, the l-board have a defective capacitor - follow this guide to replace the l-board's D5 capacitor.
Note: for the soldering step, I accidentally had my soldering gun set to 400 and burned through the trace, but there's plenty of room on the board and I was able to add a new wire to link repair the burned trace. Setting your soldering gun to 340 C and using more flux may avoid what I did.
