First off, thanks so much to all of you who have shared your information with the rest of us. You don't know how lost I'd be without it. I've been reading and reading your posts and cutting/pasting like crazy on a note pad application for my computer. So, when I received my 55LW5600 today, I wasn't clueless.

My biggest snag today was trying to set up the WiFi. Our WiFi password is a series of numbers and it took a while for me to figure out how to enter numbers, but once that was out of the way, I was able to update the firmware, then it was off to the races on callibrating the TV and the like.
Out of the box, I wasn't all that pleased with the picture, but I went with mrjktcvs's settings and, oh man, did that improve things. I might fiddle around a bit in the future, but, for right now, I'm really happy.
Tried the simulated 3D, but that is not something I'll be using that much. Can't wait to get my 3D DVD player later in the week.
If I had one complaint, it's the sound quality. Not bad, but not great. I don't want to turn on my whole audio system every time I play the TV. I reserve that for DVD's and the like, so I'm going to order the Sony 150 bar system and, hopefully, that'll do the trick.
Again, thanks all of you. Now, when my new receiver gets here, I do expect some headaches, but, as long as the thing works all right, I'll be fine.
