Hello everyone. This is my first post so forgive me if I do something wrong.

I have a hitachi seiki ht20sii and had to have the motherboards repaired. The 12volt system had an issue. They were sent overseas and repaired as far as I can tell properly. Upon reinstalling them the machine fires up no problems at all and I’m able to use the machine in manual mode. It has an error not an alarm. In white text it says (edit Abnormal 30 71). My technician that I use diagnosed the original issue and sent the boards away. He has since suffered some medical issues and is unable to help me at the moment. It seems as though the memory has been turned off. I am hoping there may be a parameter or a reset/initialisation procedure I can do to rectify this. Any help what so ever would be greatly appreciated. Thanks for your time.
