Author Topic: DP2000 certificate lost after GORE Board upgrade Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 06-06-2013 06:11 AM                     In a cinema nearby they upgraded a DP1200 and DP2000 with a GORE Board (VPF). The DP1200 upgrade worked without an issue, the DP2000 lost it's certificate. The batchinstaller tool for the certificate says it is there after running it, but the projector doesn't show it, so the Dolby will not connect. Any idea why the DP2000 behaves different from the DP1200? Initially Barco said the board was faulty - but they have the same issue with a replacement now. Did anyone come across this issue before?

Note, this can happen to ANY series 1 projector...depending on what version software you are upgrading from. The Info-T will describe the recovery procedure.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 06-07-2013 04:59 AM                     They ran the recovery process without an error - but after it, the certificate is just not available. - Carsten  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 06-07-2013 05:40 AM                     Yes, I've seen something like this. Never did get to the root cause however. Ended up changing both backplanes, power supply and controller cards. By this point 2 TI interface cards had lost their certificate The cards I removed are under test right now to determine where the fault lay, the theory is that somehow the older cards were not compatible with the Gore TI board and the battery protected DC rail that protects the memory was either shorted or grounded. Projector was OK if power left on 24/7.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 06-07-2013 05:56 AM                     They reinstalled the original board and everything was okay. A few days later, they installed another replacement GORE board, same result, no certificate available. It's now running again with the old board, but B-Input is defective (was before), so no 3D ;-) - Carsten  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 06-07-2013 07:21 AM                     and 2D will be a bit off-color.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 06-07-2013 09:52 AM                     Have you tried just backing the TI software down to 14.0 to see if the certificate shows up?  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 06-10-2013 06:04 AM                     Didn't work. They are waiting for Barco to get back to them now, the first board is under analysis. - Carsten  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 06-20-2013 07:19 AM                     Third board solved the certificate issue after checking with Barco. As it seems, Barco had a bad batch. The defective HD-SDI B port was a backplane issue - actually a bad solder joint, either a cold joint or overstressed during the board change. The installer was actually able to repair this on his own, after finding out that input B lacked the 75ohm impedance/resistance that he measured on input A. Backplane replacement would have cost something like 1000€. - Carsten  |  IP: Logged
