Service menu on Sony Trinitron

[littlecharlie]

I wanted to enter the service menu because the image when playing the consolized mvs is not center.
I entered the menu using the code Diplay - 5 - Volume- - power
And I get this menu, that searching the web haven't found something similar

So I though that was the menu, and started typing in the remote hoping that something recognizable would appear (like VPOS, HPOS, HSIZ, etc)
But instead the image tilted!
So now the image is tilted to the right, and don't know how to go back.

I eventually discovered that in this screen, if you press the "MENU" button, you get the actual serice menu

But I went to the "GEOM" menu, and there is no option to change the tilt. Plenty of option, but none for the tilt.
I've gone through the rest of the menu, and the option doesnn't appear.

So I guess I need to get to the first screen, and try to undo the tilt, but I have no idea how to use that menu.

Any ideas!? Thank you very much!!

pd: TV is a KV-21CL10E

Is the off-center problem only an issue with the MVS? If so, the MVS should be adjusted (cap on the sync line), not the TV
