Varian/Bruner 450 GC no heat/no pressure/no flow

Hello! I just had to replace my 1177 inlet on my GC and now I am not reading any flows, pressure, or anything heats. The FIDs and inlets are all doing this. It seems like the EFC has locked up. Can anyone assist with resetting the GC so this will operate? There is gas supplied to the GC and the data system communicates but there are no errors listed in the log. I also cannot get a proper septum purge calibration to perform, either.

Greetings , have you check the main board which call it mother board.
I had this trouble before and found the main board fault.
