Hi Steve and others I recently took over the Kookaburra outdoor cinema in Western Australia, originally built and run by Lindsay Morris for nearly 20 years.
In 2014 Lindsay installed digital cinema equipment, notably an NEC NC1600C projector, Dolby DSS100 server, DSP100 and CP650. Whilst the equipment is quite old by current standards, the alternative to making the investment was to walk away from everything he had built up as getting film prints was becoming nigh on impossible. The season was a success and I took over and ran the next season from November 2015 to April 2016 with no real technical problems other than the occasional ‘Lamp Unlit’ error which eventually went away, I think when I took to switching on the lamp power supply from the projector rather than the circuit breaker, or maybe just dumb luck!
It is interesting that Steve should mention the “Warning DLP Ack Fail 1207” because that is exactly what happened to me about a month after shutting down for the winter. I would fire up the equipment for several hours every couple of weeks to keep everything charged up, however one day, upon turning the projector on it came up with this wretched message.
The NEC expert said that this is usually caused by a macro and would require the backup files to be loaded to the projector. The original installer, from the other side of the country, tried remotely to reload the files, however the error persisted. They now believe that the TI board is faulty and will need to be replaced. The board is hideously expensive and will require that the installer fly across country to replace it.
Before I commit to this course of action I am curious as to what consequences, if any, resulted from the error on Steve’s projector and how it has effected presentation. I would like to think that in both our cases it is just a loose connection that can be fixed by reseating the board, but in my case I fear the worst. Whilst the macro LEDs indicate a change of function (with the exception of 3D flat and 3D scope for some reason) nothing is translated to the screen. I must also take this opportunity to thank Brad for getting me registered so that I could make my first post. By the way, it is interesting to go back to early posts in 1999/2000 and read the comments from you guys as to the impact of digital and the future of film.

DLP Ack Fail (12, 07) (error code 120, incidentally) is, to use NEC's words, "Image orientation operation fail (The feature related FMT fail)", and they recommend checking the formatter boards - it could be the red, green or blue formatter.
HOWEVER, and this is where the person from NEC tripped up, DLP Ack Fail (17, 02) (again, error code 120) is "Macro File not found.", which is correctable by reuploading/recreating the macro files (this includes the PCF, MCGD, TCGD, screen files, etc). If you are sure that the error was DLP Ack Fail (12, 07), it is NOT the macro file that is causing the failure.
NEC doesn't have anyone particularly versed in the older projectors (I am being gentle with my words - there are others who would be more direct with their thoughts about NEC's support for their series 1 machines), so it is not surprising that they might say that, as they are likely just looking at manuals, which is often a pretty limited way to be helpful.
That said, there is a formatter reset that might help, although unless you are certain of yourself, you should get a technician to do this, and it requires one of the remotes for the series 1 NEC D-cinema projectors.
If you have the remote (there is also a cable you need to plug it in. IR doesn't work for this), the keypress combination is to hold 'CTL' and 'HELP', which will reset all formatter boards.
If this does not work, regrettably, it definitely exceeds the point at which a technician/installer gets involved. The DLP control program can reset the projector (interface, processor, FFIB and FSB), but misuse of that program by someone who doesn't know what they are doing can and will result in a dead projector.
If all else fails, you will have to hope someone can source out the correct formatter board and/or the EFIB board (controls the formatter boards).
