I have got my first dust blob on my ae 500 after around 100 hours use. Its green the size of tennis ball. Its only visible on black scenes, I cant see it at all in games which is where the projector gets most use. Firstly I cant find calibos thread which details how to open up the pannies and how to clean them. Secondly can anyone who has done this and is a novice reassure me. As I am worried I am going to ruin the optics blowing liquid air all over them. As its only one am I better off leaving it ???? There are 50+ ae500 owners on here so I am sure a few of you have done a cleaning job already.
