Which DMD brands are hit by a blown lamp fuse

Among 128x32 displays only Babcock units need the 12 V and show the fault; Cherry and Dale do not. Cherry 128x16 displays can show it too. The 192x64 games add a separate 18 V fuse (F3), bridge and capacitor for the display, so a blown lamp fuse (F2) no longer affects it.
