Hello I am new to the forum however you seem to be a very knowledgeable crowd. I recently noticed my Optoma DX605 projector getting some dust inside degrading the picture quality. I then proceeded to take the top panel off and get out the vacuum and compressed air going at it like I often do. However when I put the unit back together I noticed the following picture problem and I have no idea what is causing it. If anyone has experienced this problem please help as I am stuck.
