Quoted from dlbuller:
Already posted a little about this. U23, u20, and r127 blew the day I got Champion Pub. Ended up finding a short. I just replaced all the components stated. Turned on the game and heard the bong that everything is good. It's not.
Led203 blinks constantly and 201 and 202 are solid on. The dmd will not work.
Any advice is appreciated.
At startup 201 and 202 should be on and 203 off. During normal operation led 203 will be flashing on the CPU board, 201 off and 202 on.
Have you checked to ensure you didn't blow any fuses like 601 or 602? What voltages/readings are you getting on the pins going into the dmd (j604)?
