Hi kennyc,
Reinitialising the eeprom thus, does not necessarily restore all the options to suit the set's own blueprint.
You could try entering the service mode and executing a Factory Reset. Failing that, you need to select the Option Table in the service mode and make sure all options listed correspond to those listed in the service manual for your particular model. There are usually 3 HDMI options contained therein, but I've never taken note, only to make sure that each option matches the service manual. There are usually a few that are incorrect after the eeprom has been corrupted by the power supply caps.
