Schoenorchis Fragrans-healthy for five years and suddenly pale coloring?

[DesignerofBeauty]

Hello All,

I am quite saddened, as this is my favorite orchid. My schoenorchis fragrans was extremely healthy and doing well for five years. Suddenly, this happened. I check my orchids twice daily; the orchid wasn't like this this morning if I recall correctly. I am suspecting sunburn as it was placed in brighter light temporarily. Any ideas? I know it has a keiki at the bottom. However, I hope the upper portion of the plant is not a goner.

This is a vandaceous orchid, and needs around 4000fc of light. Reddish coloring is acceptable. However, admittedly, there is a bit too much on the orchid to the right. Is this a disease/fungal infection or sunburn?

thanks!
