This TV is in good working order. Last week a visitor used the TV and since the it displays AV1 or what ever is connected to AV1. I have a PVR attached to this scart socet so it is displaying AV1- PVR. Can you tell me how to switch this off again. I have been through every menu on the hand set and TV but nowhere can I find and off setting for this display.one other thing it displays in a black box on button press but times out to white taxt. Any help would be good. Walke40

Can you explain more clearly? I understand that it's displaying only AV1, could you not simply change the input to something else?
