I agree with Marco's statement.
quote: The PIB seems to be the most sensitive part of the CP2220 projector. I had two fail last week and another about a month ago. None of these projectors are connected to UPS, which I know is hugely important, but also hugely expensive. I wanted to see what your experiences have been with failures when the projector IS on a UPS. Do PIB failures become significantly more rare, or do they still continue to occur far too frequently? As far as I'm aware, these failures have all been when the projector was power cycled intentionally, so I'm not sure a UPS would have prevented the failures anyway.
Tell us Ken, how much is the replacement PIB? I have been buying Tripp-Lite 2200va UPS for around $600-800 per location and have NEVER had any PIB failures. The projector electronics are kept awake at all times, except for extreme outages which drain the UPS.
Also, the UPS provides surge and spike protection which IMHO is more important than the back up time. (Although having that back up time to allow the projector lamp, light engine and electronics to have fan forced cooldown is super important.)
And since I protect the server as well, any power glitch means the show can go on without a reboot of projector and server, just restrike the lamp and maybe back up show a few minutes.
For a 25,000+ projector I find it disturbing that you consider a UPS costing no more than a grand "hugely expensive."

Thanks, Dave, for confirming what I suspected. I had a feeling they were failing either at power off or, more likely, power on.
Tony, why did you lighlight the part about the PIB failing when the projector is power cycled in your quote? That shows that I agree with Dave and that a UPS probably would not prevent this. Believe me, I understand the benefits of having one. And the servers and automations are all on small desktop-style UPSs, but these are not adequate to power the projectors.
As for price, A.) it's not my money, and B.) add up the cost to outfit an entire complex, and "hugely expensive" starts to seem like an appropriate term. I am not questioning the benefit of having one or that the cost is justified. My comment about the price really wasn't even relevant to my question and I shouldn't have made it. I was simply asking if a UPS would prevent PIB failures.
