One of the projectors IMB this morning was appearing gray. Well we restarted the IMB at least several times and unplugged the projector. Christie was ready to send out a tech because the IMB wasn't connecting or the NAS. Come to find out the cable to ingest the movie was still plugged in. That solved the problem. Just as simple as that.

I am adding that to the list of things to check before I call Christie.

Tell me some thing that you came across the would fix a gray IMB. That way I can add it to my check list.

We had the same thing once on our Sony, would hang in a boot-loop because of an ingest drive that was still connected. Doesn't happen with all drives, though, only with certain types.

Same here guys I thought I'm the only one that encountered this kind of bug. Like you guys I always wasted my time to reboot it and hope there's a permanent solution from this error.

Grey IMB on a Christie with an IMB-S2 has always been an issue of the CRU adapter still being powered on and plugged in with no drive inserted for us. Only exception was very early in the life of our Solaria Ones (which were some of the first units in the wild), Christie cheaped out on the CF cards the house the firmware for the IMBs and they would come up grey when the CF card inevitably failed. We actually had them replace all of the CF cards in all of the projectors once it happened a second time and the Christie NOC accidentally spilled the beans that they knew they were all going to fail eventually.

I'm just offended that they wanted to send out a tech for something so simple. It just so stupid. The over think solutions

If I were you I would be more offended if they didn't want to deal with it. Service is service, after all.

When you are talking about a half million dollars worth (or even more) of mission-critical equipment the right thing to do is to send a technician, even if the job is simple.

The tech's job is to make sure that your equipment works right and stays working.

What if it wasn't just a corrupt CF/memory card? What would you do, then? Call a technician?

I understand that you wanted to do the repair yourself. I have no doubt about your ability to complete the work.

I just think you need to look at the situation a little more objectively.

The grey IMB issue is almost always caused by somebody leaving the CRU adapter plugged in and on with no drive. Christie knows that and could just say "make sure the adapter is unplugged or off, reboot".

Because that's the problem 99.9% of the time, especially after they got all the cheap CF cards replaced.

I wish we were able to just get a tech out when, as one poster put it, "Mission-Critical" hardware goes down or software decides it wants to act funny. We have an off-site Chief Engineer who is literally states away from where he's needed most, the busiest theaters in the chain. I'm glad your fix was simple. I wish all fixes were just as simply solved.
