Author Topic: Christie CP2210 unexpected light off on show end cue Andrew Freeman Film Handler Posts: 9 From: Springfield, Vermont, USA Registered: Apr 2017 posted 01-09-2019 04:55 PM                     Unsure if anyone else has experienced this, on one of my Christie CP2210s, very seldomly when the show end cue plays, and lamp and dowser shut off, a critical error saying “unexpected light off” will pop up, usually when it’s finished cooling down I turn on the lamp and it’s fine, or if I have enough time I will power cycle and it won’t happen again for about a week. Is this just a funky thing, or should I be worried about a bigger issue? Thank you all so much!  |  IP: Logged Sean McKinnon Phenomenal Film Handler Posts: 1712 From: Peabody Massachusetts Registered: Sep 2000 posted 01-09-2019 06:04 PM                        We had this at one site we service and the tech who went changed the ballast and it went away however I can't say for sure that was the issue.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

It happens on all models we've dealt with. Christie's logging is such that it often misses the root cause of the issue. Sometimes it is the ballast (a reboot of the ballast cures it) sometimes it is a "noisy" door or air flow switch (they do age and there are kits for the CPx220/CPx230 series to better shield the switches from UV radiation.  |  IP: Logged Adrian Avram Film Handler Posts: 45 From: Iasi, Romania Registered: Oct 2013 posted 01-12-2019 12:47 AM                     Hi, Indeed, I do encounter such errors on the Christie projectors (Series 2), and in almost all of the cases the Extractor Fan interlock switch is the culprit. Also in a small no of cases the Lamp blower switch (mainly on the CP2220) is at fault for the unexpected lamps off. However my #1 problem with Christies is the red screen projected at 1st the show. Sometimes a reboot will fix it, sometime a reset of the LEQD in it's slot will fix it, until next week, or next day...who knows.  |  IP: Logged Ioannis Syrogiannis Expert Film Handler Posts: 147 From: Reykjavík, Iceland Registered: Jun 2005 posted 01-12-2019 11:09 AM                     I have the impression that the original poster (Andrew) was not talking about a critical error that was switching off the lamp, but the regular switching off of the lamp, driven from the macros received, to be reported as "unexpected".  |  IP: Logged Mike Moreno Expert Film Handler Posts: 200 From: culiacan sinaloa mexico Registered: Jul 2008 posted 01-19-2019 02:14 PM                        I had the same problem on a 2230 with CDXL-60 Lamps. We replace lamps and still so we install a CDXL-45 and it works fine. After chaching againg to CDXL-60 the problem starts agains so we had to replace the lamp power supply and problem solve.

And also IIRC, it will only sometimes bring up a "Ballast Comm Lost" error as well? Been over six years since I last saw that error at one of my older installs. (I have been away from it for that long, that is..)  |  IP: Logged Juan Jose Vazquez Film Handler Posts: 16 From: Queretaro, Queretaro, Mexico Registered: Jun 2018 posted 01-19-2019 07:41 PM                     I have the same problem that they mention, in my case it only happens when the End cue is executed in the middle of the show. if it ends normally, the error does not happen. Christie CP2215 with lamps CDXL-18SD and CDXL-23S. Regards! Juan José.  |  IP: Logged
