We got one of the 62's at our shop today and I spent some time calibrating it (I've been doing ISF for about 10 years). It replaced the 195 that was sitting in the same system until last week. I also did a new Toshiba 56 yesterday.
I would say it is a small but noticeable improvement over last years. More natural looking and slightly better contrast.
The service menu acts a little funny while adjusting values and the screen on both of them was no where near centered (about 3-4% high and to the right). Also the grey scale was off QUITE a bit on both, even on the warm setting. Don't fool yourself about it being close enough, just get it fixed.
Also about the black levels, they are excellent for these type of sets but you have to be kidding me about being as good as a properly adjusted CRT. Every once in a while I do an old Toshiba 480/1080 CRT and I'm reminded how far we have to go with black level and colour to get back to where we were 5 years ago. The Fujitsu hanging on the wall in the shop comes closer to the black out of a CRT.
All in all it's a great set that I could happily live with.
