To All,
Many thanks for your very helpful suggestions. After understanding the schematic diagram flow from IC2 to Display, (and general circuit labeling, thanks KM6WT) I conducted the continuity check. All checked out. Understanding the microcontroller was not getting commands, I decided to check out the other connections pertaining to the microcontroller. I started at XTAL1, and guess what............I completely skipped over that installation and went for the TCXO installation. WHAT A DOPE!!!! I installed the crystal and boom up comes the display. I was hoping there was a simple explanation, and it was.
Now I can resume with the alignment. I hope this was the only issue I'll have. Thanks again to all who supported me. I received a good education.
