Very sorry to hear about this. So did this TV work fine on FIOS before you switched to DirecTV? And does this happen every time you switch the channel?
I recently changed my TV provider from Fios to DirectTV. The problem I have is when I change channel on DTV occasionally the picture auto switches to 3D. Then I have to push the 3D button on remote to go back. Anyone having this problem? I did just update the TV software. Thanks for the help.
