instruction but the TV does not respond. The only thing we can do is power off at the wall and start again.
The TV has the latest firmware and has the following connected per HDMI....
Vodafone TV (T-Box)
Xbox One
Chromecast
It also is Internet connected per Ethernet.
The TV has exhibited this behaviour whilst using the T-Box, Xbox One and internal TV tuner. When this has occurred there has been no particular activity e.g changing inputs and the TV is at normal operating temperatures. We have not changed its
location, connected devices. The TV is approximately 3 years old.
Any ideas what could be causing this?
