I've never heard of shutting off a valve in order to bleed. I've always done
it with the valve open.

Are you sure you know how to bleed the system PROPERLY? An air pocket
could
account for one zone working fine and another one being cold.

Well, when I bled each zone, closing its shutoff valve and opening the purge
valve, the water coming out was solid and flowing. I let it run for a
while, and then bled them again. And yes, I had the supply running.
