I've reached this room:
and this is the pillar.
Going into first person mode to get a closer look and I've translated this to be: UP A RT LT A DOWN LT RT
...but nothing happens.
I tried translating a room with a grey pillar and white bit on the floor too, but nothing happened there either?
Are you supposed to press the actual buttons in sequence in first person mode, or not? Do you have to stand on something, near something? I don't get why it's not doing anything. I can see the pillar showing the things I press in this example, it looks right to me.
