I have had a TCP42GT25 since May and have been generally pleased with it. Sometimes I wish it was a little brighter, but it's a minor issue compared with the great colors that I'm enjoying. Tonight, when I turned it on and went to Vieracast, I got a message that a software update was available. I pressed OK and it did it's thing without interruption. The TV rebooted and announced that the update was successful. I went to Vieracast again and noticed I had more options to watch. Mainly I use Netflix. I did a little searching around and then went over to Netflix and watched for awhile. Then I went back to regular TV (cable). When I tried to go back to Netflix, it said server unavailable. I rebooted my router and the TV and this time it went to Vieracast but the boxes that show the selections, ie. Netflix, Youtube, Facebook, Twitter, Picasa, etc. are just blank boxes. I can't access anything. The new software version is: 3720. I also went into settings and did a connection test and everything shows OK. Is there a way to revert to the old software version? Anyone else have this problem? I have 10 more days of my 90 day Costco trial left and would hate to have to return it for this, but will if I have to.
