Metz Accent 70 Service Mode

Hi
I already by a Metz Accent 70 28'' 16:9 CRT Television.
It have a "little" problem with the geometry, in the THX test the one with 2 squares and an circle the lines of the botton and the left doesn't see very good.

I think that the "fail" is too little to call the support service.

Anyone knows how to enter in the service mode to modify the geometry settings.

I already try to use the Argos procedure (Turn off and Turn on with buttons +/- hold) buts this don't work

Any Help?

Any web with codes?

Thank
and sorry for my English
