Hi All,

I’m having some trouble with my Road Show DMD. The DMD turns on but the display is all jumbled. I checked all my voltages with a multimeter and all low-voltage checks out. High-voltage that comes from the secondary transformer is roughly half of what it is supposed to be. Everything else in the game works just fine as far as I can tell. Is it common for the secondary transformers to fail? I measured my voltage at the DMD board as well as at the DMD controller board. I measured the high voltage at the Molex plug that plugs into the DMD control board.
