Okay, just an update:
Got a Denon AVR 4300-CI REFURB from BestBuy (missing one of the two remotes, the low functioning one for multiple rooms... But I use a Harmony anyway) for $1000 to get the 3d.
Installed an Epson 6010, and couldn't be happier. Looks great out of the box. While I was putting it up, tweaked the ceiling mount a bit for the anamorphic lens, which USED to be mounted on the JVC, but now has a separate ceiling mount and looks SLICK.
I was excited to get everything fired up. Did my audio room calibration, firmware updates, repeogrammed the Harmony, etc, loaded Green Lantern 3D onto the PS3 (hey, back off! I've never seen it before! And I don't have a lot of 3d movies!).., and NOTHING!
Wasn't sure WHERE the problem lied. Directv worked, but with a Denon refurb, well, the possibilities were endless. Anyway, after trying things too numerous to mention here, discovered my Playstation 3 was the issue!
Apparently, the PS3 HDMI port HATES thunderstorms!
I haven't seen this posted as a PATTERN yet, so I am putting it here: Playsation 3 HDMI ports are unusually sensitive to thunderstorms. There are some bewildering tales out there of damaged HDMI ports even with surge suppressors, even, in some cases, with power unplugged (?) (though unknown if Ethernet/hdmi still attached).
Note googling "HDMI" and "thunderstorm" brings up a bunch of horror stories, but it SEEMS PS3s are a little more delicate. That said, depressing info about surge suppression from the outlet being only one source, but cable/sat inputs and HDMI as a conduit once a surge enters the system dispels an illusion of easy surge protection, even with unplugging. Sigh.
Anyhow, the nonHDMI PS3 is out of the theater, and a new one installed today.
Just tried it out and the 3d works! Looks/sounds great!!
Now to find inexpensive but good 3d glasses. Need about 4 more, some kid sized.
Looks like the most expensive are the Epsons. But the Panasonic TY-EW3D3 series (available in small, med, large) are good, as are the Playstation 3D glasses.
My Sony 3d glasses, sadly, were not. Oh, well.
Anyhow, thanks everyone for the advice.
Thinking about surge suppression besides at the power strip (like Brick Walls), like coax and Ethernet.... Hmm.
