I participated in the thread you referenced by the previous post and have the same issue. I'm nudging this thread because it's newer of the two (relatively speaking) and I came here hoping that someone had had some luck getting this fixed.
I have "game night" for console gaming every other week at my place and it went months without ever resetting during those 3.5 hour sessions, but for the last two game nights, there's been one/two resets. It also resets once about every three movies watched (so once per ~6 hours of operation?) Mv VW100 "ruby" never had any problems of the sort (it had plenty of its own issues to be sure)
It is not:
- power (dedicated 20-amp circuit, tried with and without high quality UPS)
- hdmi cable (issue occured with DVI from HTPC as well)
- AVR (see hdmi above)
- heat (has happened at a variety of ambient temps, at a variety of power-on durations (though it seems to need to be on for at least 30 minutes or so to occur))
What I do know is that it acts almost like a full power down. The lamp is off, the receiver loses HDMI signal, etc... then the lamp comes back on, followed by the "Starting...." notice in the corner.
If it gets bad enough to be more than an occasional inconvenience, then I guess I'll be stuck buying a new projector, because Sony seems to think it's some external factor (even though clearly it's a recurring reported issue for this model).
On the bright side, I still have no regrets! As odd as it sounds, it bothers me less than the things that bugged me about the VW100 (for which I paid a great deal more years earlier). Just hanging in there until 4k projectors hit the right price point (if the vw85 can last that long)
Until then, I would love to know if anyone with this problem managed to get sony to fix it...
