Soak the pot and medium in water for about 10 minutes and then slip the pot off of the roots. If all is good, repot it like it was. I suspect you will find some rotted roots and will need to repot the orchid in a fresh mix though.
On the oncidium, the one with the wrinkled older pbulbs, I didn't do the root exam. It has four working flower stalks, so I didn't want to disturb it, plus the couple brown leaves just fell off, and there are numerous healthy leaves on that plant! When it's done blooming ill repot it too. But for now, just a nice bath... It seemed happy with that.
It's strange that all the orchids in bloom seemed to be dropping their flowers and leaves at the same time. Except for the Phalaenopsis. They are growing some nice huge leaves there, and the one that dropped its flowers was due. But a couple of those hybrids didn't keep their flowers very long. Especially the spidery looking Mtssa. Kauai's Choice 'Tropical Fragrance'. Those blooms didn't last more than a week or two.
Just coincidence, or something else perhaps? The current PBs aren't shriveling, so could it be water? And I have fertilized.
Many thanks for all of your advice!
