My dryer won't power up

Control board was bad so we replaced it. Plugged it in and turned on breaker. Still same as before replacing board. Lights on the right side of panel are flashing. We have power coming in. Power cord is fine, outlet is fine, door switch is fine, all checked with a meter. Tried to enter Diagnostic, won’t do anything. Checked Thermal fuse and it’s fine. Lights on the right side of panel just keep flashing but nothing else works!
