Just attach the COLD AND DARK.cfg to your reply, and I can compare it to mine. Be aware that I copied the P3D\Captain_Sim\767-II\panel\basic\COLD AND DARK.cfg, created by CS, and installed with the 767 Captain II, and pasted it to P3D\Captain_Sim\767-II\panel\custom, then renamed it DEFAULT.cfg. That worked for me.
My usual  method is to load the 767 II into P3Dv4/v5, then after my default panel setting loads, I use the CDU and switch to the COLD AND DARK, and the 767 ends up in a cold and dark setting. I can't even access the CDU to do anything until after I've turned the Battery Switch ON.
