Author Topic: NEC DLP CommE Fail Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 12-31-2016 09:19 AM                     It seems these warnings can usually be solved with a reboot/repower of the projector. Just wondering that it seems they only occur on NEC projectors? Do they hint at something, or is it just the usual type of complex electronics hickup? It seems none of the NEC software updates ever got rid of them. - Carsten  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 12-31-2016 11:56 AM                     Could be a bogus router, that is the most common failed part in an NEC. You will see this "DLP Comm Fail" warning very briefly if there is a GDC server & IMB connected to it running 8.XX Firmware. Once the server's IMB establishes communication with the T.I. stuff the error automatically clears. You will see the lights on top briefly go red then green again and it is a normal part of the boot process. I can't speak as to weather a Dolbly IMB based server does this or not.

So it could be the router, any of the ethernet cables to the backplane or even the dreaded card reseat. Did the projector also throw out a number with the CommE?  |  IP: Logged Buck Wilson Jedi Master Film Handler Posts: 894 From: St. Joseph MO, USA Registered: Sep 2010 posted 12-31-2016 05:29 PM                     We had this error last week on a 1200c coupled with a strong electrical fire smell, and the screen looking like a broken phone or tv screen. Unbelievably a reboot got it back up on screen an it's been fine ever since. The magic of digital.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 12-31-2016 08:46 PM                     quote: Steve Guttag Did the projector also throw out a number with the CommE? The full message was: 'Warning - DLP CommE Fail(000000:Conn=2)' There is no way to use the projector or wait for it to clear by itself. We always seem to need a full power off. Well, 'always', it happened three times in two years... It's an early NC900C. It only happens at boot time, never after it has started up alright. - Carsten  |  IP: Logged Kristo Nalo Film Handler Posts: 24 From: Skopje, MK, MK, Macedonia Registered: Nov 2016 posted 01-03-2017 06:12 AM                     It also happens to me before we reboot it and it's okay. But I wonder what's the best moved to that error or bug.  |  IP: Logged System Notices Forum Watchdog / Soup Nazi Posts: 215 Registered: Apr 2004 posted 03-02-2019 06:04 AM                 It has been 787 days since the last post.  |  IP: Logged Tom Wienholt Master Film Handler Posts: 371 From: Towson, MD, USA Registered: Dec 2002 posted 03-02-2019 06:04 AM                     140 : DLP CommR Fail(046500:Tout=4000) 520 : IMB:ICP Communications Status 584 : IMB:Marriage NOT Active 586 : IMB:Service Door Tamper I am getting these error codes on an NC1200c. Tried power cycle and reseating cards and ethernet cables. Same issue. There are no LED's lighting on any card except the IMB. Any thoughts?  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 03-02-2019 06:14 AM                     Did you reset the tamper event and try a re-marriage? Do you know how to do it? - Carsten  |  IP: Logged Tom Wienholt Master Film Handler Posts: 371 From: Towson, MD, USA Registered: Dec 2002 posted 03-02-2019 06:20 AM                     Yes, the tamper clears but the IMB will not remarry... Remote connection to the projector keeps going in and out, if that is relevant. (DCC software)  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 03-02-2019 09:09 AM                     Your problem is the lack of communication with the ICP. You indicate that it isn't light up. So either it isn't getting power (Check the LVPS) or the ICP itself. Be aware too, something else may be sucking down on of the low-voltage rails preventing the ICP from booting. Ruling out the ICP module is simple enough by moving it to another projector. Note, it is the security manager's job for reporting security issues. That is either going to be the Enigma or the IMB. So, when the IMB doesn't see the ICP or doesn't get the all-clear from the ICP, it will report and maintain a security breach. So though the IMB is reporting the error, it doesn't mean the IMB is the cause, it is just the messenger (and gatekeeper). It is upset that the ICP isn't right, in your case, based the message presented.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 03-04-2019 08:13 PM                     Don't forget the GDC external media block servers will briefly throw a comm failure and turn the tail lights red whilst booting up. But this only lasts for a few seconds, and as booting continues the comm warning clears and the tail lights turn green again. Mark  |  IP: Logged
