Dust blob or something else with my Marantz VP-12S2
Watching a movie last night, I notice a small "blob" at edge of top image, LH side.
I pause the movie, clean the lens with an optical cloth. still there.
I pause again, switch inputs. still there.
I go to Avia test screen. still there.
I search the room for some unseen obstruction (cobweb?). no dice - still there.
Of course, now I'm watching this little spot all the time. Like a blob of dust or something is obscuring the pixels. Pixels fire and color as normal, but in this one spot pass an off color (ex: the "blob" show as blue on a white field).
I've done some searching here on lint blobs and most of the screen images I see are round-ish. What I see on a 110" screen is more of a claw or hook shaped form, wider at the top, curving and narrowing to a point. About 1 1/2" in length, sort of "rainbow-ish" when you look up close. More visible on brighter scenes, gone in dark scenes.
I'm going to get a can of air today and see if that'll clear the lens better. I understand the VP-12S2 to have "sealed" optics, so I don't want to mess inside the unit at this point.
I've checked the room for possible relfecions, but no dice. This is a very dark dedicated room.
stumped.
What is this and can I fix it? Optics? Bulb? Lens? What?
Thanks in advance for any insights!
