Author Topic: Anyone having a CP-650 "freeze up" and lose control? Paul H. Rayton Expert Film Handler Posts: 210 From: Los Angeles, CA , USA Registered: Aug 2003 posted 11-19-2005 04:49 PM                    We have had a "mysterious" (for lack of a better way to describe it) experience with our CP-650: It apparently "freezes", in that the master fader refuses to move (or, at best, moves up or down very slowly), and the format select buttons become inoperative. It still seems to pass sound through, maybe in "bypass" mode, but for the most part is unresponsive to commands. We have remedied this by re-booting the system, but that can be inconvenient if the show is running. This is actually our second CP-650, we changed out our original unit for precisely the same reason: freezing up. We have been leaving the system on 24/7, and I'm wondering if the daily boot-up sequence might be better for the system. Is anyone out there leaving their 650 on constantly, and having any such problems?  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 11-20-2005 01:07 AM                     Wonder if the OS in that system needs to be reinstalled since sounds like something inside is starting to decay. ..maybe the power supply could be decaying and not putting out enough "juice" to the system. Try a swapout between units with the power supply and see if the power supply could be the culprit. They do go without letting you know. Course, I'm relating to CP-500's and CP-55's with this sort of problem, but wonder if CP-650's could do the same.... ..just some ideas to begin with.... -Monte  |  IP: Logged David Favel Jedi Master Film Handler Posts: 764 From: Ashburton, New Zealand Registered: Feb 2002 posted 11-20-2005 02:27 AM                     I had that problem when I fried a circuit board.

It happened a few times, at first we solved it by rebooting then we added a power conditioning from FURMAN and that solve the problem  |  IP: Logged Paul H. Rayton Expert Film Handler Posts: 210 From: Los Angeles, CA , USA Registered: Aug 2003 posted 11-20-2005 06:11 PM                    NO remote fader, and no automation. This is a completely manual operation. We've left the system "on" at all times because of some other elements in the system we did not want to power down. But now that the second CP-650 (which is 100% new hardware, direct from Dolby, and has been installed for about 2 months now) is getting the same problems, I'm beginning to think that there possibly is some connection to never being turned off. Accumulated error messages, perhaps, from long periods of no signal (I know, doesn't make much sense!) or other data somewhere, which is (apparently) cleared by shutting it off.  |  IP: Logged John Vincent, Jr. Film Handler Posts: 16 From: Eastham, MA, USA Registered: Jul 2003 posted 11-21-2005 08:24 AM                        We had the exact same problem you describe- went through much troubleshooting and swapping of cards and finally got a replacement 650. We would re-load the software, it would disappear for while, then reappear, leading us to believe the memory chip that holds the software was corrupted. The ONLY other thing with us that might have caused the problem was our booth monitor failed and was replaced at the same time (Comp. Eng. MS-55), we think there may have been some stray voltage coming out of our booth monitor back into the 650. But we were never able to verify it.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 11-21-2005 08:35 AM                     Dirty power is the number one cause of digital systems corrupting themselves I use a UPS that provides the output power via the inverter and battery all the time and have almost put an en to all te dsp stuff loosing their settings  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 11-21-2005 08:49 AM                     Ahhhhhhh, the truth about this processor slowly reveals itself.....

Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 11-21-2005 11:11 AM                     The CP650 remains the most reliable processor I have ever worked with, bar none. We do have Tripplite IBAR-12 or LCR-2400 in all of our racks. We have had two power supply failures.

Is something we always use on cinema processors down here in Cyprus. But if you had the same problem with the previous processor maybe you should check your connections between booth monitor/amps/projector etc. Check for any strange voltage passing through. Also check that the power socket of the processor gives a stable current which is not fluctuating. If it is fluctuating, most probably that is your problem. Do you have an identical screen or is it a single screen theater? If you have an identical you could try swapping the processor with another screen (but you need the software to download the data and reload on the other one and vice versa). If though you don't have the technical ability to do it, is better that you bring an experienced technician to mess around and try to find the problem.

Can't say I've ever seen that happen to a CSP around here. I know Canadian hydro is a bit shaky at times. I remember how bad Keith had it up there... especially in the summer. Actually all of the 650's we've installed have been completely trouble free.... if they only sounded good...... Donno if they ever had any software updates done or not... they're not in my servicing area.

My CP650s sound absolutely fantastic!  |  IP: Logged
