Sky Q replaced Sky HD - no signal to non-Sky Q TVs


Novice Member
We have had Sky Q installed replacing Sky HD. There is a Triax (part 370419) one in two out box which used to connect into the SkyHD box, but this isn’t available on the SkyQ box. The two TVs we have that we don’t have a mini-box on now get no RF signal. Is it a case of buying a power supply for the Triax box or am I barking up the wrong tree? Any suggestions gratefully received! Thanks, Peter


Hi and welcome to the forum.

Did you/do you have a separate aerial plugged into the Triax, or did you entirely rely on the connection and output from the Sky HD box ?

(I'm presuming this is the right part - TRIAX - TRIAX Link - 370419 ?)

thank you tickedon. I don’t know about that I’m afraid. The engineer did change some connections and of course Sky say it’s not their problem. I tried plugging the Triax into the HD box to power it but no avail. I don’t want to buy a power supply if it won’t work! Many thanks, Peter
