So I get home and my wife tells me the tv won't even turn on anymore. Sounds like the same problem krisjan was having. Now, the power led is flashing red (5 times) and the set won't even turn on anymore. I called Sony for support, and the only thing they had me do was unplug the tv (from my surge protector), leave it off for 2 minutes for the tv to reset, and plug directly into the wall. Same issue. So I called Circuit City back and they're ordering me another new unit since this is less than 30 days from purchase.
So far, I have loved this tv while it was working, and that was just in SD. Was supposed to have HD cable box installed tomorrow. I hope I get a good, working tv with none of the green tint issues (I had no picture quality issues to complain of).
I'll keep everyone posted. I'm guessing around a week for the new tv to arrive.
