I had my new WD-62725 Mits delivered and 5 days later broke. Screen is freezing up and turns green then goes to partial like split screen then may go to screen like has noise interference lines running across horizontally. May go blank and only sound. Ultimate Electronics was great the way they handled it. Sending a brand new set out right away. Very pleased. For $4k I was hoping to get at least 7 days of service out of it. Anyone know what in the world might be wrong with it and if I can expect issues like this with the replacement one.
