FWIW, the DE 128x16 DMDs have their own integrated display processor and associated display ROM. When the DMD boots, the display processor shows the display ROM version and then waits for commands from the CPU board over the 26-pin ribbon cable.
If you're just getting the boot screen and nothing after that, there's a communication problem between the CPU and display processor through the 26-pin ribbon cable.
