That's good, its ok serial 1 not working as it will use serial 2 or 3, only one is needed. I just wanted to verify and all hardware to get it going is working. Also because controller never shows startup complete it means it's hasn't gotten to the point where it want's to talk to display. If it said startup complete but display still hung on one red dot then it would be related. I don't know what else to suggest, did you try the eeprom erase steps I mentioned?
