I have a customer running GM Digital Signage on two Sony Bravia TV's, with Google TV built in. It worked just fine on both TV's, till a week ago one would not complete the load-up of the GM Digital Signage app. it starts loading and just hangs on the Load screen. I have uninstalled and re-installed the app on the TV. It is set-up the same as the other TV but as I said it just hangs at the loading screen. any recommendations?
