Author Topic: NEC Focus Memory Paul Stevens Film Handler Posts: 42 From: Galena, Ohio, USA Registered: Oct 2006 posted 02-12-2012 09:19 AM                     I noticed a random problem with the NEC series 1 & 2 projectors with focus. The projectors can hold focus positions for months until suddenly it is out of focus. Re-saving memory positions after adjusting them back fixes the issue for the moment. I wonder if this is a bug we just have to deal with for now.  |  IP: Logged Adam Holland Film Handler Posts: 66 From: Oak Grove, LA Registered: Nov 2007 posted 02-12-2012 09:50 AM                     I had the same issue with my Barco DP3000 a few weeks ago. We are only open Thur-Sun so were turning it off nightly thinking that was the best thing to do, but after we completely lost our lens settings decided to leave it running like the big boys and haven't had that problem, cross our fingers, since.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 02-12-2012 11:24 AM                     Its rare, but I've seen it happen to every projector.  |  IP: Logged Paul Stevens Film Handler Posts: 42 From: Galena, Ohio, USA Registered: Oct 2006 posted 02-14-2012 08:54 PM                     It happened again today. It effects all formats as well. Not close ether. Also happened once with lens positioning. Another bug for NEC to try and fix.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

That is, Model of projector, Firmware version (service pack) and lens model.  |  IP: Logged Justin Gorka Expert Film Handler Posts: 174 From: High Wycombe, England Registered: Apr 2006 posted 02-18-2012 05:38 PM                     We've had the same problem for some time now. Seems to be series two NEC's though!  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 02-18-2012 08:33 PM                     I have had NECs definitely go wonky on keeping their lens settings. However, most folks have found that the In-Visions lenses are the worst offenders.  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???"

Refocusing and then re-saving the lens files "fixes" it -- although I wouldn't honestly say that the problem is fixed. Paul -- Looking at the dates on your original post and the 2nd one, it seems like you lost yours again after only 2 days! Is that right??  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Try saving the lens settings under a different file name and then updating your Macros with the new file name. -Steve  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???" Posts: 4247 From: Bloomington, IN, USA Registered: Feb 2002 posted 02-19-2012 02:17 PM                     Thanks Will do. Was that just released? My last firmware update (to 1.7.78) was in late November.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 02-19-2012 04:09 PM                     1.8.85 has been around for a little while now. Also, the ICP, for Barco is up to 3.2.340 (will allow HFR stuff, among other things). If you don't have Communicator 4.5.7 on your PC and 4.5.9 on your Touchpanel, they are due too. 4.5.7 and beyond will allow firmware updates via communicator to the projector, touchpanel and the ICP...it handles all of the projector rebooting too.  |  IP: Logged Justin Hamaker Film God Posts: 2253 From: Lakeport, CA USA Registered: Jan 2004 posted 02-19-2012 05:50 PM                        We have 12 NEC NC2000C projectors. 10 of them have the inVision lenses; 2 with Minolta lenses. We have never had to refocus the 2 with Minolta lenses and those were installed about 18 months ago. 2-3 of the projectors with inVision lenses need to be focused fairly regularly; the others have had to be refocused from time to time. I have been told by others that this is a known issue with the inVision lenses. One thing I've been told as a possible fix is to run both the focus and zoom out to both extremes and then execute your existing lens file. I have had mixed success with this, but it's probably better than rewriting the lens file every time you are out of focus.  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???"

I've contacted Barco.  |  IP: Logged Ray Derrick Master Film Handler Posts: 310 From: Sydney, Australia Registered: Sep 2001 posted 05-16-2012 09:15 PM                     I have seen this problem with NEC Series I machines but not so far with Series II. I think the easiest way to fix it (in the case of NEC and if you have access to the DCC software) is to do a lens calibration. It only takes a short amount of time and would save having to spend time trying to refocus each format. This could even be done remotely by your service company.  |  IP: Logged
