Hi All,



I have a Optoma HD29Darbee Projector and would really appreciate a bit of help trying to pinpoint this weird artefact (hard to describe, almost like some fuzz or a wire hanging down or something?) that appears in the top center of the projected image noticeable when using the Test Pattern function and scrolling through until it says "Full White".

This only started appearing after I did a deep clean of the projector. I was very careful, followed lots of YouTube videos and wore Nitrile gloves the whole time when handling the projection assembly. I did not touch the light tunnel, I only cleaned the DMD chip, mirrors and lenses with a microfiber cloth. I have taken it apart and put it back together several times and have been unable to figure out what could be causing this display anomaly.



Any ideas?



Thanks,

Martin
