[* black] Follow the light path and inspect carefully for dust or contamination. These pictures show the optical assembly upside down. | |
[* black] Light enters from the lamp on the right, facing the screen (on the left in this picture since it's upside down). | |
[* black] The light then passes through the colour wheel ... | |
[* black] ... and into the collimator. | |
[* icon_note] If dust or contamination has been sucked into the projector by the fan, it can deposit on and around the collimator, resulting in shadowy patches on the projected image. |
