Author Topic: Electrohome/Christie DLV 1280i Projector Fault Ben Wales Jedi Master Film Handler Posts: 602 From: Southampton. England Registered: Jul 99 posted 12-21-2007 06:35 PM                     I have recently bought a Electrohome DLV (Digital Light Valve) projector and I have found some faults with it. So far I had to replace the Lamp as it had reached well over 4,000 hours and had quite a bad flicker. Since I have set this up I still notice a Blue Circlular spot in the centre of the screen, at first I assume it was the old Lamp, but this still remains. I get this Blue image even on "Black Test Patten" and have tried to adjust this out with Colour/Brightness/Contrast adjustments etc but with out success. The Video Component feed works correctly and there is no picture shifting etc, except for this Blue Hue in the background. Is this a fault with one of the (Blue) Mirror Panels or could this be adjusted?. I have already tried the Flicker Adustment as well, it may be the projector is worn out as the logged hours is 30,000 hours.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 12-21-2007 06:53 PM                     sounds like the blue panel got a good case of burn-in and needs to be replaced (someone [probably left the unit on for a long time without any video feed and just the blue panel was being used) - being the longest light frequency. Here's some info for you to peek at.  |  IP: Logged Ben Wales Jedi Master Film Handler Posts: 602 From: Southampton.

The Dots are quite visable, is this the case of Panel damage or something else?. Although the Projector is old and Christie no longer supports them since 2006, I have replace the Lamp a few years ago and want to use until the Lamp fails.  |  IP: Logged
