Hi, some help ( hitachi seiki ht30J / SEICOS 300J)

I was changing the control's membrane (big control keyboard), so I had to remove the 2 PCB boards from the front control cabinet.
After reinstalled the 2 PCBs and turn on the machine; Surprise, the machine interface has changed, to the original YASNAC interface, NO the Seicos interface.
The parameters are OK because the machine can move and go to origin, but the softkeys and alphanumeric keyboard don't work.
I didn't remove the battery.

please any advise
