After a recent move, I've noticed that a section of the screen is SLIGHTLY darker than the rest. The section starts about three inches in from the top-left corner, and goes diagonally down and ends up about an inch in from the bottom left corner. The pixels are all in the right place, so I don't think the mirrors would have been bumped. They're just darker. Since it's along a diagonal, it almost looks like there may be some kind of internal film that is slowly pulling away from the screen. Does anybody know what could cause this? |

So it is most likely that one of the lenses may have collapsed when you moved the TV and a portion of the light beam isn't reaching the screen causing this darker image. And this link shows you a schematic and a description of the light tunnel: http://www.oerlikon.com/ecomaXL/index.php?site=OPTICS_EN_lighttunnel This link will give you a much better idea of the filters that are inside the light engine. http://electronics.howstuffworks.com/dlp2.htm I hope this helps, Good Luck Andrew. |
