Author Topic: Blue line down the middle of the screen on series 2 Barco? Marin Zorica Jedi Master Film Handler Posts: 671 From: Biograd na Moru, Croatia Registered: May 2003 posted 01-16-2016 08:23 AM                     Yes, definitly to try out DVI on projector itself and too see what is happends. it could be IMB problem, a few weeks ago i have situatio when cinema had picture but whole green. It was like projected true green filter. After all testing, projector test pattern, as well DVI played fine, but HDMI or DCP (all what is going tru IMB) was green.....so doremi agreed to send IMB and problem solved.....unit was still under service period, or else something like EUR 5500 i think for IMB?  |  IP: Logged Bob Ezra Film Handler Posts: 75 From: Carbondale, CO, USA Registered: Apr 2001 posted 01-22-2016 11:50 AM                     was this resolved? if so some feedback would be helpful...  |  IP: Logged Marin Zorica Jedi Master Film Handler Posts: 671 From: Biograd na Moru, Croatia Registered: May 2003 posted 01-22-2016 05:46 PM                     Similar issue today......projectionist called me and says he got some vertical lines on screen as well some red, yellow and magenta color flashing over picture whole time. Did try to reboot projector/server few times but it did not help....after that i lead him to take out IMB and rest of cabling, he did reseat IMB and cabling and picture went back to normal....  |  IP: Logged Andrew Thomas Master Film Handler Posts: 273 From: Pearland, TX, USA Registered: Jun 2012 posted 01-22-2016 10:28 PM                     So current situation: I did the .x update that GDC's tech support recommended in case it was an IMB firmware issue. No change. I then get on the phone with Barco's tech support, I describe the issue and he says (like most people) the three of four things it could be. At this point, I'm getting the blue line on any signal (the DVI and ICP patterns, DCP content from the IMB). But I noticed something kind of strange. When I would cycle through test patterns, sometimes the next pattern would load with no blue line showing up. Switch a couple more times, and it would show up. There was no, ehem, pattern to this. It wasn't specific patterns that would cause it to go away or come back, and no particular number of times cycling before it would go away/come back. So I mention this to the Barco tech and he says, while telling me also not to get my hopes up, that he doesn't think it's a light engine failure due to the intermittent nature of it and that it sounds more like something somewhere is loose. He e-mailed me the service manual and suggested some areas to look at. Noting that it is out of warranty anyway, he suggests a couple of places to look. I went through and reseated a few of the connections on the signal backplane. I boot back up and no blue line for almost 90 minutes of run time. Prior to this, every single time we played content, we couldn't get through the first trailer without the blue line appearing. Tonight, the line didn't show up at all during the first feature and so far hasn't show up during the second. So, yeah, I have no idea what's up.  |  IP: Logged Andrew Thomas Master Film Handler Posts: 273 From: Pearland, TX, USA Registered: Jun 2012 posted 01-24-2016 11:22 PM                     So, the blue line showed up during the second trailer and then went away the entire rest of the night. Any new ideas on why this is happening?  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 01-25-2016 04:23 AM                     ICP or Light engine. One test could be to swap, say, blue with green and see if then you have a green line on screen. That would mean it's the ICP. If the line stays blue, then it's the light engine - or the cable loom. May want to reseat the connectors on the backplane/formatters too The above should be done by a qualified engineer - I strongly recommend you shouldn't DIY.  |  IP: Logged Andrew Thomas Master Film Handler Posts: 273 From: Pearland, TX, USA Registered: Jun 2012 posted 01-25-2016 11:36 AM                     Reseating the formatter connectors on the backplane seemed to have been what caused it to go from happening all the time, to the extremely intermittent issue it has become. I'm wondering if it might be a bad cable or connector on the backplane itself? Everybody I've talked to with light engine failure issues didn't seem to think it would be that after all the info I gave. And honestly, if it is the light engine, I would just buy a whole new projector as that I can finance with no problem...so I'm not worried about futzing with it. It's just a big computer, which I've been building since I was 8 years old  |  IP: Logged Andrew Thomas Master Film Handler Posts: 273 From: Pearland, TX, USA Registered: Jun 2012 posted 01-31-2016 12:27 AM                     Ok, newest update. Blue line came back, came up from there very first clip during the first feature all the way until about 20 minutes into the 2nd feature. Now here is the interesting bit...it went away within about 10 minutes of me taking the side panels the control side off. I verified that the temps were all in the normal range with the cover on, but could it be a temp or airflow issue?  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 01-31-2016 07:02 AM                     Intermittent contact issues are ALWAYS temperature related, no matter wether these are within spec or not. It would hit me hard if I'd had to replace a light-engine or whole projector 'just' because there is a stupid wonky contact pressure somewhere. As far as I know, the formatter boards need to be attached with a spec'd screw torque for safe contact. That gives you an idea how delicate it is. - Carsten  |  IP: Logged Andrew Thomas Master Film Handler Posts: 273 From: Pearland, TX, USA Registered: Jun 2012 posted 01-31-2016 03:47 PM                     It's definitely frustrating! I think we will just move forward with the purchase of a new unit, and set aside some cash to repair this one at a later date as we plan to add a third screen anyway.  |  IP: Logged Buck Wilson Jedi Master Film Handler Posts: 894 From: St. Joseph MO, USA Registered: Sep 2010 posted 01-31-2016 05:23 PM                     Digital.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 01-31-2016 06:04 PM                     Barco should be able to offer a 'repair/exchange' light engine or to repair the faulty one - if you're happy not to use the projector for a while.  |  IP: Logged Andrew Thomas Master Film Handler Posts: 273 From: Pearland, TX, USA Registered: Jun 2012 posted 02-04-2016 02:47 PM                     So after another weekend of it randomly appearing or not (two nights nothing, one night 60% of the time) we had a Barco technician come out from a recommended servicer of Barco themselves. Not shockingly, some issue in the light engine. I spoke to a guy at Barco and they said they can likely repair it, but that involves sending it to Belgium and waiting a minimum of 8 and up to 16 weeks to get it back. In the short term, there doesn't seem to be any new light engines for this model in stock, only refurbs. I can't with any legitimate business sense pay $20,000 for a refurbished light engine that carries a 90 day warranty. I've yet to hear what a new light engine gets as far as warranty, but I assume at least 1 year? But as we are planning to build a third screen, I think our best option right now is to buy a new projector and send off the light engine for repair. If it turns out the repair cost is too high, then we can wait and buy a brand new light engine when we need the projector up and running for the third screen. Definitely not what you hope to have to do 60 days after buying the place!  |  IP: Logged Jason McMillan Film Handler Posts: 68 From: Houston, TX, USA Registered: Dec 2009 posted 02-04-2016 04:54 PM                     Andrew, Do you mind if I ask which drive in you purchased? Was it the Showboat, by chance?  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 02-05-2016 01:47 PM                     they won't charge you 20.000 for a refurbished light engine - if you return the old one.  |  IP: Logged
