Follow this link for all you vi queries.

For this query use
Eec

First check this in a test file

If the lines are really empty (no spaces or tabs):
:g/^$/d

Otherwises:
:g/^[ X]*$/d
where X is a TAB character which is difficult to type in the forum.

You may want to use sed i.s.o. of vi.

And to add an alternative:

# perl -pi -e's/^\s*$/ and$_=""' file

will delete all lines in file "file" that have only blanks

Enjoy, Have FUN! H.Merijn
