So, AVS has been very sympathetic to this issue and has a call into JVC. In addition, I reached out to Art Frierman for the Projector Review website and he has contacts in the top PR, Engineering and Project Administration levels and has assured me that "JVC" is now aware of the catastrophic failure of the HDMI input (my words, not theirs). With next week being CES, Art and some of the people from AVS will, no doubt, corner these guys for some answers. Lets just hope they have some by then..
Ditto about January 2nd being a work day...the postal service was open for crying out! I don't think there's any reason for JVC to send ANYONE to CES unless this problem has been fixed!
So, while typing this I just fired my pj back up...it still won't see my AppleTV, PS3, DirecTV box but is syncing up to my Sony BDP-S790 just fine... hey, if its only gonna see one source, I'm glad it was blu-ray.
If you are still experiencing HDMI input problems like these, please email firstname.lastname@example.org
and tell them. If they don't have it fixed by end of next week they'll have to issue a cease and desist for my emails and phone calls...if it doesn't border on harrassment, I'm not doing my best!
