Phg / cant find the entrance to the ice temple. Stuck here !!!

[SilverAmethyst]

I really hope someone is able to help me as I feel pretty stuck (and maybe a bit stupid :S because it looks easy...)
I am at the the Ice Temple and defended all the Yook's ; now I'm in this chamber 1F on the Walk trough.
I did all as descried in the walk trough but when I came to this triangle switch no door opened.
So I can't enter the temple.

I was actually fixated on the 5 red blocks in the East corner (I hoped would lower)...
But after trying for a wile I opened the walk trough look
what I missed. So that brings us back to above....
PLEASE HELP !! Am I REALLY STUCK ?!!
