Problem after head board replacement...

[SignJose]

Hi guys
One of the sensor color wires on Falcon was loose. I didnt notice it until i replaced HEAD BOARD. Now all it prints are those lines (see below)
I followed all tests from the manual, i even replaced both fuses on Main Board, but no improvement.
Does anyone knows what else may happened ?

Thanks
Gene
