Are you sure they change it ? As i installed an octo on mine and the sky guy left it on when i had skyQ and it worked fine
As for the Sky Q boxes@GerrySwe you need to send em back or they charge you an old sky box will work to get you freesat channels but if memory
Serves me correctly you need a viewing card that is paired to that box to view……….could be mistaken tis been a while.
Buy a freesat box or a freesat compatible TV or even better a viark box…..your call mate
