When trying to change channels on Sky using puk streamer, the screen sometimes freezes, last channel sound still on and no reaction to remote -after between 30 seconds and 4 minutes, I get a " please wait" notification then revert to the start up screen. Have to set up tv channels (again) and carry on as normal.
I have tried all the suggested reset actions but I still get the freeze - usually 2 or 3 times per evening.
I suspect that the puk is on the way out but cannot find a method of requesting a replacement
