Hi, i have here for sale a Optoma UHD35STx. This projector is a open box item that is in excellent to near mint condition. i just notice some really faint, small scratches and tiny scuffs on the bottom, a tiny gap along the bottom edge, but please see my images and judge for yourself. This still has the protective plastic on top and the lamp security sticker is still intact. The tiny cable that attaches the lens cover to the projector is broken. The lens cover doesn't stay on, i don't see any damage to it. I will place a couple strips of tape on it to hold it in place for shipping. The projector works perfectly as it should and produces a beautiful, very bright image. ISSUE, This has a couple small, really faint orbs that i could only notice with a very dark background. These orbs are very common even with new projectors. It also looks like a really faint smudge mark in one of those same areas that i could barely notice when viewing a white background. I uploaded several images and only noticed these issues in my last two pictures, please see my images and judge for yourself. These issues can be repaired by cleaning out the tiny dust particles that are behind the lens. This sale includes the projector, lens cover, remote, batteries, power cord, the original box and packaging. The box is distressed so i will double box this to better protect it. This item will carefully packed up and shipped fully insured.
