Author Topic: unsolved lens automation issues on Barco seriesII - anyone? Brendan Penny Expert Film Handler Posts: 121 From: Bundoora, Australia Registered: Dec 2008 posted 02-06-2011 11:04 PM                     Yeah yeah heard all that before for the last two years. I have tried ensuring the lens is not near the precious micro switches. Hmm funny that it happens on all 60 of our projectors in the field. what a coincidence.... We are going to try sacrificing a small Goat next week. Will let you know how that goes. Good luck with that microswitch theory!  |  IP: Logged Sam D.

I had the same frustrating experience until I found out about 14.01 if I remember the number right. Not everyone seems to know about this. It's definitely fixed the problem at both my locations.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 02-07-2011 10:57 AM                     Brendan: What does Barco say about all your sixty machines not performing to spec? - Carsten  |  IP: Logged Brendan Penny Expert Film Handler Posts: 121 From: Bundoora, Australia Registered: Dec 2008 posted 02-07-2011 01:23 PM                     They say urr arrr urrr maybe ummm arrr ohhhh arrrr arr ummm arrrr hey what's that over there?  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 02-08-2011 07:10 PM                     Why don't you kick their asses then? -Carsten  |  IP: Logged Brendan Penny Expert Film Handler Posts: 121 From: Bundoora, Australia Registered: Dec 2008 posted 02-09-2011 01:02 PM                     Too much effort and they already know very well about this problem. I guess its not the end of the world as it probably only happens a few times a year on each projector. Usually due to power surges. There are a couple of projectors that have never done it to me oddly enough so maybe electronics power filtration is the go. I just recommend as part of training, projectionists know how to reset and save the lens files. Takes only a minute to fix.  |  IP: Logged Arnoud Edens Film Handler Posts: 7 From: The Hague, Netherlands Registered: Nov 2010 posted 02-27-2011 02:55 AM                     (First of all, this is my first post here, so 'hi' to everyone ) I've seen some problems recently with lens settings on series 2 Barco's; especially on the 32B model. Had the problem on 2 different machines. Both of them seemed to trash their lens files every now and then. On loading a lens file, instead of changing to the correct lens setting, they would only home the lens. (Like in the home and return, but without the return) After this, the lens file seemed to be damaged or lost as well. Switching to another lens file worked fine, but then switching back to the first, the lens would go back to the home position. Last week however, Barco released a firmware upgrade (at least for the 32B model) version 1.5.56 that should fix this problem. This update should also fix another lens problem on the B models, where the lens step counting sometimes failed a bit, which was resulting in some small drift in lens position over time.  |  IP: Logged System Notices Forum Watchdog / Soup Nazi Posts: 215 Registered: Apr 2004 posted 06-27-2014 04:09 PM                 It has been 1216 days since the last post.  |  IP: Logged Thomas Evans Film Handler Posts: 1 From: Birmingham, West Midlands, UK Registered: Jun 2014 posted 06-27-2014 04:09 PM                     I tested this today as I have issues with the Barco 32B lens change Barco Series II Lens Function Change Duration (DP4K-32B) Ran the following test with the lamp on, douser open and content paused on screen Benchmark tests 4K Flat 2D to 4K Scope 2D = 23sec 4K Scope 2D to 4K Flat 2D = 23sec NB: image size changes to match relevant aspect ratio, image zooms out, image focuses. Alterations Confirmed lens installed was same match as lens selected in Lens Parameters = correct Ran the lens Homing and return function to re calibrate the lens 4K Flat 2D to 4K Scope 2D = 23sec 4K Scope 2D to 4K Flat 2D = 15sec The speed of the scope to flat change has improved Amended lens settings for both flat and scope and saved to relevant function 4K Flat 2D to 4K Scope 2D = 23sec 4K Scope 2D to 4K Flat 2D = 15sec No improvement after changing the lens settings Re-loaded saved lens settings No improvement after re-loading lens settings summary The lens change takes approx 23secs from flat to scope and 15sec from scope to flat. When changing the image disappears for 2 secs and re-appears filling approx 50% of the screen Next the image zooms out while moving slightly off centre before filling the screen correctly Next the image focuses, this stage takes the most time. All of the above is visible on screen as we only have 8 seconds blank from the house logo to the rating. The same happens in 3D functions also.  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???" Posts: 4247 From: Bloomington, IN, USA Registered: Feb 2002 posted 06-27-2014 05:29 PM                     The thing I hate most about my Barco DP2K-32B is the lens. I have one of the InVision, and I hate pretty much everything about it. Not only does it vibrate, but I also find it necessary to constantly fiddle about with lens settings. Especially focus, which tends to drift over time. Eventually, the situation worsens to the point where writing over an existing file has no effect. At that point, my last resort is to delete all of the lens files and start from scratch.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 06-27-2014 05:41 PM                     Everyone had that focus drift problem with the InVision lenses running on .89" projectors or if your Invivion lens also focus's for a larger projector. The only ones that actually work are the ones for the NC-3200's and NC3240's. And I have even had to fix those twice now out of the box because the position encoder and motor were not set correctly and the lens wouldn't zoom all the way. They obviously have ZERO quality control at that plant! The two large NEC's actually slide the lens mount to focus. So there is just the zoom to get working right and it doesn't drift. Strong took back all of the .89" InVision lenses they sold in the field and replaced them with Minolta or Fujinon's. You should squawk loudly at Barco or the dealer that sold it to you and see if they'll do the same for you. Not one of those lenses works correctly and focus will actually drift out of focus during a 2 hour show!! The glass in them is very good though.

Depending on the lens size you need will depend on what manufacturer will make the lens. For example, if you have an Invision, there is no such Minolta equivalent. Basically, you're stuck with it, and yes they drift badly. Christie uses 100% Minolta lenses.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 06-27-2014 06:35 PM                     I've seen that, but I assumed it was normal for the lens. I don't know much of optic but some lens will require a great focus adjustment when switching flat/scope on a constant height screen. Some others are faster. Unless Barco have slowed down the focus motor, I'd say it's normal.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 06-27-2014 07:57 PM                     That's bullshit Brad. Minolta or Fujinon makes all focal lengths of DLP lenses. Just look towards NEC or Christie for the list, and there are some very long throw and some very short throw lenses available from NEC that aren't even on the standard list. Christie does the same and they have lenses all the way down to 1.0 ratio. What it amounts to is Barco is unwilling to commission Minolta or Fuji to make a run of lenses for their projectors, sure it's dam expensive. The Nvision lenses from Strong were ~$500 cheaper then the other makers lenses. They say they brought them in to ease the back orders during crunch time... it may have for a short time till they had to replace them all anyway.

In fact, where DID I say that Christie uses 100% Minolta lenses. Also my entire post above was Barco specific. What I said was with Barco you're stuck with whatever lens manufacturer made the particular focal length lens that you need for your particular auditorium. You can't just complain at them that Invision lenses suck and get a Minolta version of that lens. (Believe me, I've tried.) This is because Barco only offers that one option, despite having different part numbers stating otherwise.  |  IP: Logged
