I have been working on a DE Star Wars. No DMD. I replaced with a fully working and tested DMD, I replaced the DMD driver with a new one. I also replaced the power board with a new one. Finally, I replaced the ROM chips with a brand new matching set, one on the dmd driver, and the other on the CPU. NO ACTION! I tested continuity on all wires, checked solder points on all connectors. No action! The game plays, just no DMD. Throughout the troubleshooting process, I re-tested the DMD and driver on a DE Lethal weapon, and works fine. I gave up and the game has been sitting. Any advice!?
