Probably experiencing more root loss.
When you removed the dead roots, did you repot it back into the same sized pot or did you use a smaller one that fits the size of the roots?
Over potting is a big problem with epiphytical orchids. It doesn't allow for a proper balance of air circulation and moisture.
The size of the pot should match the size of the roots as best as you can.
If that can't be achieved, then mount it.
Also when you repot, it shouldn't be put back into the same media. Fresh media should be used.
Some people cannot grow their Phals potted because of their growing environment. Be aware of this. Sometimes the only way to go is to mount it.
Other people use semi-hydroponics successfully.
What kind of potting media are you using? This can also be an issue, particularly if an epiphytical orchid (an orchid that grows on trees) is being grown as a terrestrial plant (as in grown in potting soil - bad for epiphytical Phals).
