I called Epson about my "Auto Iris error".
No wait in a phone queue, and their phone suport was very professional. She asked me a few questions, but not the Spanish Inquisition. I did make it clear during my description that I had unplugged it from the wall after the first incident and gone to a different circuit for power. Thus eliminating some sort of "memory" issue or power issue. I run my PC & 2nd time also the projector off an old datacenter-class APC Smart-UPS so I wasn't too concerned about power glitch anyhow. She indicated it certainly sounded like a hardware problem without giving me much trouble and offered either of their warranty replacement options.
Still thinking about it. Send it back & replace? Or return, and wait and see on the 5010? Decisions decisions.
I have to say just based on their phone support whatever I get will be an Epson.
