Dying orchid

[Latina]

Dear members,
I am new to this forum and would like to say hello to all of you.
I have orchids for 4 years and their number is growing slowly. All of them are phalaenopsis and i would say that i have some experience with them. They are growing and blooming and are really nice.
But last year i decided to try a new kind of orchid. I still don't know if it is miltonia or miltoniopsis. However, at first it was nice and green. But gradually it started to loose its leaves. Last weeks it became brown and i think that it is dying. (not think but sure )
If some of you have more experience and could help saving it, would be great
I will attach a photo so that you can see what has left from this orchid.
Thank you in advance!
