I JUST got mine fixed the other day. Apparently the repair place was sent the wrong part, so it took a long time (almost 2 months total). My main board went on the TV. He replaced it and it's all good now, except that I have to redo all my settings (argh!). I finally got around to watching a show last night and being on a 42" TV for the last few months has made me appreciate this TV again. It was just so, so nice to watch.Mine did this a few weeks ago. It was during my move so I have a claim in with my shipper. There is no power at all, exact symptoms you are reporting. I am trying to move to a 77A9G.
