My new Samsung tv not recognising Sky Q box. Says no Signal and check power device

[RobertHaines]

My new Samsung tv keeps not connecting to Sky Q box. It says no signal and check power device. The only way I can get it to connect again is reset Sky Q box. I spoke to Samsung but they told me it's an issue with quality of hdmi cable. I am using hdmi cable that came with the Sky Q box. Samsung said I should use high-speed HDMI cable or HDMI 2.1 cable. Anybody else had this issue?

HDMI cables can fail but are cheap to replace. You can get a high quality HDMI 2.1 cable from Amazon for around £5.

It'll be quicker than asking Sky to send you one.

You could try this:-

Ensure tv and sky q box are both switched on.

Press Home button on Samsung TV remote.

Press up arrow on Samsung remote to select the menu bar.

Scroll across to the Sky TV tab and press ok

Now select dismiss button on Sky remote and the Sky output should now be on your screen.

Is this another case of a samsung TV crashing the Q box if you turn off the TV while the Q is still on?
