Author Topic: NEC NC800C error Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 12-12-2013 07:29 PM                     We have an NEC NC800C projector. Today when they started it, an 2 errors came up. Error 52 Security Tamper and 53 Component Side Door Open. The book doesn't even have these 2 codes. I called NEC and even they are having trouble with it. I'm sure the 2 codes are for the same problem. There is no door on the component side besides the air filter. The other weird thing is the BluRay plays fine through the projector in the bluray macro. Picture is fine. When the DCP plays we have sound but just snow for picture.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 12-13-2013 06:58 AM                     HDMI playing but not DCP is 'normal' for this situation with security tamper issues. Strange NEC is not able to help here. Probably a bad security switch/cable/connector, or someone actually opened housing parts for some reason. - Carsten  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 12-13-2013 08:18 AM                     I've seen an NEC coming up with the tamper error - whitout nobody tampering with it - which cleared simply rebooting it!  |  IP: Logged Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 12-13-2013 08:37 AM                     I know nobody tried to open any of the panels. They tried rebooting a few times with no help. All side panel screws are tight. There are no door or locks on this projector. I guess because it's a series one projector not a lot of people at NEC deal with it much. They were going to call me today.  |  IP: Logged Stefan Vogels Film Handler Posts: 48 From: Aarle-Rixtel, Noord-Brabant, Netherlands Registered: Jan 2010 posted 12-13-2013 03:50 PM                     I have seen this error many times on a series 1. Error 52 and 53 combined. And in all cases it turned out the interface board was gone ( broken ). It needs replacing before encrypted content can be played again. It happens to a lot of series I projector's after several years.  |  IP: Logged Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 12-13-2013 04:03 PM                     You mean shorted out or something? It wouldn't "break" by itself.  |  IP: Logged Stefan Vogels Film Handler Posts: 48 From: Aarle-Rixtel, Noord-Brabant, Netherlands Registered: Jan 2010 posted 12-13-2013 04:13 PM                     The cause is not clear, NEC is a bit fuzzy about it. However it does mall-function and won't set up the secure link anymore.  |  IP: Logged Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 12-13-2013 04:17 PM                     On the phone with NEC again. He says that sounds like it's possible. He's checking with other people now...................................... Yep. They say it's the board. Thanks for the suggestion.  |  IP: Logged Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 01-30-2014 06:44 PM                     So after 6 weeks of waiting we finally got the board. I put it in the error messages that we had are gone but now I have an error 26 Tamper-Switch Activation Detected and I cant clear it. I tried rebooting with and without the DCC program.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 01-30-2014 06:49 PM                     You mean this machine was out of operation for 6 weeks with you waiting for a spare part? - Carsten  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 01-30-2014 06:58 PM                     DCI requires a physical presence to clear a security tamper so all projector companies have devised a means that mere software alone can't clear the final error. You have to manually do it. For Christie, it is the marriage button (on series 2s), on Barco it is the dreaded Dallas Key (aka ibutton), and for NEC...is is a special code. Now I'm not familiar if the NC800, being a series 1, also requires this to clear it (I'd have to check) but it is worth a try.  |  IP: Logged Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 01-30-2014 06:59 PM                     No. BluRay ran fine through the DVI port because it doesn't go through the interface board that was bad. With the new board in, BluRay still runs fine and we lost the errors we had. We just now have the new Tamper error. I've done it with the series 2 projector. I have all the codes. I don't remember the series 1 having any codes.  |  IP: Logged Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 01-30-2014 11:57 PM                     quote: Richard May So after 6 weeks of waiting we finally got the board. quote: Carsten Kurz You mean this machine was out of operation for 6 weeks with you waiting for a spare part? Last month I had a similar issue with a Series II projector that started off the exact same way. ("Tamper" error codes) The projector was down for 5 days while they diagnosed the problem and got the parts, which had to come from Japan. Fortunately, we only lost one show, since we still had 35mm changeover capabiltiy and were able to get film prints for the all the screenings we had that week. But in almost 30 years of projecting, I've NEVER had a film machine down for more than 24hrs, and 99% of the time you could save a show using a paper clip, rubber bands, wooden coffee stirrers, duct tape, etc to fix the projector until you got the part you needed. The DCP projector was down for SIX FRIGGIN' DAYS. But remember- - it's digital, so it's "better."  |  IP: Logged Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 01-31-2014 06:12 PM                     NEC has everybody on this one. There are no passwords for the 800C to clear the tamper. They sent me a screenshot of the troubleshooting code that I got with steps to check. I checked what I could and nothing yet. What's worse now is that Bluray doesn't work anymore. We only get snow like with DCP. For now were using a smaller video projector.  |  IP: Logged Jason Raftery Film Handler Posts: 72 From: San Diego, CA, USA Registered: May 2011 posted 01-31-2014 11:07 PM                     I believe Stefan is correct. While I don't support any 800C's, I do have 1600C and 2500S machines and they share the same error code set. On the latter models, errors 52/53 point to a dead gore interface board. Might also double check the projector's error log and see if it logged a host of successive failures. Here's an example from the last gore board I ran across that went into a tailspin following the last show of the day before expiring completely a few hours later in the middle of the night: 2014/01/15 10:38:57(96) MF(B) Test Fail 2014/01/15 10:38:57(95) MF(G) Test Fail 2014/01/15 10:38:57(94) MF(R) Test Fail 2014/01/15 10:38:57(44) IB File System Fail 2014/01/15 10:38:57(51) IB TPM Self Test Fail 2014/01/15 10:38:57(50) IB Activate Setup Fail 2014/01/15 10:38:57(38) IB RTC Serial # Fail 2014/01/15 10:38:57(37) IB ANC FIFO Test Fail 2014/01/15 10:38:57(36) IB Framestore Test Fail 2014/01/15 10:38:57(35) IB FPGA Reg R/W Fail 2014/01/15 10:38:57(30) IB Diag Not Performed 2014/01/15 10:38:57(24) Interface FPGA Fail 2014/01/15 10:38:57(23) DSP Fail 2014/01/15 10:38:57(22) ARM Fail 2014/01/15 10:38:57(21) Self Test Fail 2014/01/15 10:29:11(140) DLP CommR Fail 2014/01/15 07:57:47(49) IB Active Data Fail 2014/01/15 07:57:47(20) System Fail 2014/01/15 07:57:47(120) DLP Ack Fail(1707)  |  IP: Logged
