Line on 645Z Viewfinder

Recently after my trip from Africa, when I returned back to Singapore, I noticed there was a black line across my viewfinder.

Thinking it was probably me scratching the focusing screen (which itself is vulnerable to scratches) , I swapped to another focusing screen but the line still appeared. I look at the mirror elements and there was no scratch or line across (it was dusty thats all). Cleaned it properly and still it was there.

In no way does this line affect the IQ of my images or anything. Heck I call it the permanent rule of thirds line now :P

I am not sure whether some moisture from my Victoria falls escapade could have gotten onto my pentaprism.

Sent an email to Ricoh JP for enquiry as well. Any guesses gentlemen?

Check for something between the focus screen and the pentaprism. The only other likely place would be between the eyepiece and the pentaprism.

Focus screen to pentaxprism nothing. For the latter, how does one do that with the 645?

You have to look at the viewfinder from a slight distance and from different angles. Shining a light through the eyepiece might help.
