Are some of those lines due to switching events? You guys are the electronic experts, but this problem seems almost universal. All my DSLR cooling mods required separating the analog - digital grounds and connecting the cold finger and camera chassis to power supply ground - no more lines.
Looking at the schematic and PCB, an inductor between mosfet source and ground, as well, might help.
