Sharyn, this is exactly what happened to my phals as well. Check it out:
I didn't presoak the bark well and although the roots were ok, the top aerial roots dried off. Then I watered them more frequently and misted in the morning and ta da!
Just look at the leaves, the whole plant seems "taller". It even managed to start a new spike off a node AND grow a nice healthy aerial root. Well, switching to s/h did help, but the second photo was taken on the day of the transplant.
