And now the Rest of the Story:
My *new* 5010 was delivered to me Tuesday by Certified Electronics. Not in the box, but still covered with the styrofoam "blanket". It looked like they just swapped my old stand onto the new panel. Guy was very nice, helped me get it all connected and verified working. I signed the papers, thanked him, and he departed. I immediately jumped into the service menu to verify the time on the panel: 0 hours, 9 minutes!! Sweet. I think the 9 minutes were from our connection/testing. Brand new! I then applied D-Nice's viewing settings and enjoyed for a few minutes.
Later, I had to go to my daughter's dance recital that evening. When I returned, a violent storm had gone through. We were then without power for 24 hours! After power came back, I had no cable until this evening! I finally got to view some HD tonight. Picture is incredible. It is possibly better than my previous panel, but also may just be the relative look compared to my 19" computer monitor I was using.
So, in the end, it all worked out very well. I am really pleased with Pioneer and each person I talked to there was very friendly and helpful.
Special thanks again to Aric from Plasma Concepts for all his help and information along the way. Above and beyond anything I expected!
