Is the sky box connected with a scart or HDMI lead to the TV?
If you do not know what I mean please let me know thanks
Kate you do not need to tune in the TV at all......simply switch on the box>>pick up the TV remote and find the INPUT or SOURCE button on the remote continually press it about once every second until the sky box comes through, then when it comes through you need to go into the settings of the box itself with the box remote to make scart the "priority" input
Let me know if you have problems

Or use the INPUT button on the Tv itself if you do not have the remote control
Do you still need help with this please?
Kate I would be grateful if you would respond thank you
