Someone reading from the Torah gets the singing note (trop) wrong for one of the names of Hashem, in a manner which changes the meaning of the verse. He then needs to go back and repeat the name of Hashem to gets the note right (O Ch 142 (1) MB ).
How should he do it? Can he repeat just the name with the right trop or must he complete the possuk and then repeat it with right trop (as I have heard on occasions)?
