Purchased my second T5442T-ZE from Andy's Amazon store Friday (thanks Andy), got it yesterday and installed it last nite. All looked good until this morning when i reviewed footage and found artifacts in the middle of the screen and on the left margin. Outside of the lens is clean and undamaged. I'm guessing there is a fingerprint on one of the inside lenses? What do you guys think? I've attached a shot from this morning and tonight.
