Last year I bought a D800 that works very well, but had a cracked top LCD glass due to poor packing by previous owner. Too bad. I don't know if Nikon would replace the glass due to camera age, I am too cheap to find out. Bought a "replacement" from a US parts seller, it is plastic and does not fit well. Had no luck getting it to stay down. Just received what appears to be an OE glass lens that has a black perimeter at least on one side (I have not removed the protective film on both sides of the glass yet). Also the kit came with a gasket with adhesive on both sides. I am thinking it would be best to put the adhesive down on/in the body, then put the glass on? I have the channel in the body cleaned out fairly well. Anyone had success with this?
