We grabbed one of these last night. Noticed an interesting black translucent "wave" going from right to left for the first hour of a DVD movie (commercial store bought) and then it stopped. Afterward we switched back to cable and on the lighter screen saw that we had a vertical line of dead pixels left of center. OK, fire up online tech support and did all the tests it suggested; our result: "dead pixels, call the warranty service number". Now it's gone. Yikes! Anyone know what's up? Frys offered to get us a new unit in a day or 2 but I don't want to do that if it is component or wiring related.
Wow, know anybody who wants to purchase one of these models, is on sale at Fry's $1499.00 for the 630 and $1799.00 for the 650 model store pickup only.
