You can't edit a binary PSD file as a text file. As you have seen, you damage the file.

You have to open the file in Photoshop, find the Happy New Year text layer, select it and modify the "Happy New Year" font using the Type Tool. Commit the change using the checkmark in the top Option bar, save and close the file.
