My LT150 has been used for 42hrs. I found three 3 inch spots on the right upper corner of the screen. I was sure those were from LT150 but not the screen. It was easy to see the spots when there was no input signal and just showing the NEC logo.
At the beginning, I believed those were the finger prints on the surface of the lense. However, after cleaning the surface of the lense, there were still three spots but shifting to the left upper corner.(The projector has been moved and turned up-side-down.) When I rotated the focus ring, the spots were still at the same position. So I believed the spots were not on the surface of the lense but somewhere internal. Can I remove the lamp to clean the internal surface of the glass facing the lamp?
Some times ago, I found the semi-circular plastic arc below the lense was loose and raised up that caused the lense cover not to be pluged in. I pressed the arc down and then pluged the lense cover in. After that, every thing seemed to be normal. I don't know if the dust got in from gap when the arc was loose. Anyone found the similar situation?
