Thanks Frank.. I doubt it's the EEPROM, since I remove the vertical yoke connector and get a horizontal line. Lately, it seems I decide to do what I think is going to be a quick repair, while I wait on parts for another set...and it's ends up not being the norm...gets frustrating. Someone sent me the schematic of the vertical section, so hopefully I'll get it on Monday.

I "see" possibly a broken trace to the vert at the solder pad of the IC, or possibly a bad crimp connection to the yokeconnector, assuming you used a quality replacement for the vert ic. "Fraid thats all I can think of. You should also be able to run that chassis with the eeprom totally removed, as PCE only stores customer preference data in the IC on that model.
