PC casting to Sky Q

[MikeC12341]

Hi after a replacement 2tb Sky Q box I find my PC can no longer cast to my 65" Toshiba. The only change is the replacement Sky Q box after the HDD crashed, I've reset, the router, and TV and PC, also the WPS, Sky have no idea, but the only difference in three days is the new sky Q box. Help this 70 year old please.

Hi @MikeC12341   If it is a new box, have you checked that the software has been updated? Q280. Just to be clear, are you casting to your TV (nothing to do with Sky Q) or to your Sky Q box?
