I have researched info on this probem, and found a fix, but I don't understand how it is done. Here is what the tech wrote - "Record 12C Buss settings, then "memory initi" and put back in the recorded data". Is this done from a service menu? Anyone how to access it? I'll do more searching for the fix procedure, but was hoping this group would be able to help. I tried to download the service manual for free, but the Hitachi website is now prompting me for a user name and password. Anyone familiar with this problem? Thanks as always group.

Appears that you record the 12C settings on paper, do a memory initialize resetting everything then put back the 12C settings. I would assume this could be done via a serviceman's menu mode.

I have no idea how to enter that mode and it may take finding someone who does or purchasing a service manual.

Do you all mean I2C?

No I mean 12C which is what the OP posted. Maybe it is I2C but I wouldn't know the details unless I had hands on with the Hitachi sets that use this method.

I had hoped that the OP would have replied, since I quoted him first and said 'you all' and not the "y'all" of southern U.S. dialect which may imply the singular personal. Just wondering if there was yet another proprietary bus (buss) out there to confound testing.

I just got to work and had time to check for responses here. Thanks to all that replied. I did manage to find a little more info regarding this, and it is done through the service menu, as Meat plow said. I think I know how to get to the service menu also. I will post a follow up with the menu code, and the fix Monday I hope.
