dwp99 283 Posted March 9, 2017 Hello, I'm no expert but I believe the U37 which in missing is a capacitor. You'll need to find another photograph of one where the component is still intact to get the number off of it. Nope U indicates an Inseparable Assembly IC R's are resistors D's are Diodes L's are Coil, Inductor, Bead, Ferrite Bead and C's are capacitors https://en.wikipedia.org/wiki/Reference_designator schematic diagrams are probably nonexistent since most things today are throw away. I read on another forum that the main board should be about $209.00 "From Tee Shirt forum May 8th 2015" Yeah same thing happened to my cutter. Your motherboard is gone and you would have to order another one. I believe there are about $209. I just upgraded mines and got the expert pro. That's a common problem on the expert 24 I was told.... Found this place but no main board for the Ex-24 http://www.expomedios.net/repuestos-spare-parts.php?marca=GCC&l=&mode=list Hope this helps. Doug 1 Share this post Link to post Share on other sites
