We recently switched back to Fios from Comcast. We are now experiencing an issue when changing the TV input back to the Fios input. The TV will briefly display whatever is playing on Fios at the time but then shuts the TV off. The TV will automatically reboot. It's annoying because it takes the TV about 20 seconds to restart. We never had this problem before with Comcast and Fios when we previously had it.
The TV is a Vizio XVT553SV.
