Trash...or not to trash?

[piaffe97]

I've got 2 phal plants that I'm not sure are going to make it. Both were repotted after blooming because they were in damp and moldy smelling moss when I bought them. I changed over to store bought orchid mix with bark and charcoal. I feel like the roots are unhealthy and the plants themselves are dying. You can see how dark the leaves are on the first plant. I trimmed all the dead/blackened roots before repotting. Any suggestions/advice? (I only have a little moss on top of the bark material)
