Terrible news. You're the third person I've seen here who has working audio but black/blank screens that only work in Recovery Mode and no where else.
Check the threads here:
Black Screens, Everything works in system update mode, Error when camera disconnected
N3DS XL Black Screen of Death
I haven't found anyone yet who has recovered from this very specific, permanent soft brick.
