Author Topic: DP4K-23B red(ish) line artifacts Alec Tisdale Film Handler Posts: 1 From: somervielle, MA USA Registered: Sep 2013 posted 09-23-2016 08:29 PM                    Hi, I just started having this problem: Hopefully you're looking at an image I uploaded of a side shot of a 10'x 20' screen with a white test pattern generated from a Barco DP4K-23B. This red(ish) horizontal line on the bottom third of the screen is visible at all times (all channels, PCIe and DVI inputs). Anyone out there have any ideas what this might be and/or how to fix this? Thanks!  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Read the directions on how to upload an image. You should have a line in your message that appears similar to this: [IMAGE]http://www.film-tech.com/cgi-bin/showpic.cgi?dir=uploads1102&file=sample.jpg[/IMG] Except the first bracket will also be IMG and the actual file will be what you upload.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 09-24-2016 04:28 PM                     Check with test patterns. The standard test patterns are generated in the ICP. I would reseat the ICP (power off, and you have to reauthorize with the Dallas key afterward). If still there, you can swap some light engine wires around and see if it follows the wires (ICP issue) or stays the same (light engine issue). Looking red means you probably lost green... looking at the colour bars or pure colour patterns should show exactly what"s going on.  |  IP: Logged
