Author Topic: Christie CP-2220 Green Hue on Screen Nate Anderson Film Handler Posts: 20 From: Stillwater, Maine, USA Registered: Sep 2004 posted 08-16-2016 05:54 PM                        I just noticed that there is a green hue where all the white should be on the screen. My first instinct is light engine but is there something else I should try first? Thanks in advance.  |  IP: Logged Martin Daian Expert Film Handler Posts: 227 From: Montevideo, Uruguay Registered: Jul 2003 posted 08-16-2016 06:43 PM                    maybe will need a DLP selftest, i solve that problem on my CP 2000 M opening the cover and with the key open the tamper wait a few seconds and close again and the problem looks to be solved. At least on my projector. Also try to move the cables, will be a false contact on the cables that go to the DLP boards.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

These are generated by the ICP so you remove all of the color correction stuff that may influence your judgement. If you put up the full scale white and it is white, then you've eliminated the DMDs and the light path. then put up a grey/greyscale and if that looks good, you are down to either the source isn't configured properly or the MCGD/TCGD (PCF) files are not proper for the source material. For instance, using a DCDM RGB instead of a DCDM XYZ PCF file could give you a color shift like that. It is a lot easier to fix once you know where the source of the problem is.  |  IP: Logged
