Question Weird artifact on screen which looks like a rainbow hair (DLP projector)


Novice Member
Hi, well yes the title says it all. I have this weird artifact since yesterday with an Optoma HD131Xe. I have replaced the lamp 6 months ago and everything was fine. Now I bought a projector screen and wanted to set it up but before I even began, I saw this...


Any idea what this could be?
So far I have removed the lamp and checked the color wheel. There were some specs of dust on it (on the inside) and I managed to remove them:


Yes I know, this was incredibly dangerous/stupid but it worked. However the artifact only changed slightly which indicates that it might be related to the color wheel:


Thank you for your ideas,
