LG TV which has stopped recognising the Sky Q box

[dm2386]

I have an LG TV which has stopped recognising the Sky Q box - it simply says no signal, having been working fine in the past. I have tried rebooting the Sky box etc (which also works fine on another TV in the house). The loss of Sky coincided with the loss of BBC channels on Live TV - these are now working, but with very poor picture quality. Any ideas?

@dm2386  Try the following:  Power up Sky Q box, wait a couple of minutes,  then on the Sky remote press the following buttons Home1080Home, this will reset the output on the Sky Q box to 1080 and the TV should pick it up again.

I am having the same problem and that did not work

Ensure the tv is on the correct connection - usually HDMI1 but could be HDMI2. If you have pets then they can step on the remote & change settings.

Thank you for your suggestion - I have tried this, but unfortunately it makes no difference.

As I said in the original post, the Sky Q box works on another TV (Samsung) in another room.

The problematic connection is on the LG TV, but this is wall mounted and connected by an HDMI cable which does not come into contact with anybody / thing which might have dislodged it!

You haven't inadvertently changed the TV setting to default to Freeview.

I'm not familiar with LG tvs but it might be worth checking the TV menu settings.  but there may be a tab to select Sky TV on a menu tab as per a Samsung TV.

I was referring to changing the input via the TV remote, it's possible to accidentally click on the input key then change it which would affect what's shown onscreen.

Check too that the HDMI cable is still connected to the back of the Sky box, also try a different cable.
