Hi Derek, My name is***** will assist you.I am sorry to hear that you are having this issue.This sounds like it is happening due to a bad connection, what happens in these issues is the tv responds to signal loss and tries to find a working signal on a different input. That is why it goes to the Freeview channels. This could be a bad cable that goes from the Sky box to the Panasonic input, you can try a different cable. If that does not correct the issue then the that will mean that the Panasonic input board is failing and will need to be repaired or replaced.*****Please let me know if you need any other assistance.Please take a moment to rate my service positively.Thank you very much!
