Fantastic TV, but developed a fault within 6 weeks
[This review was collected as part of a promotion.] I feel a bit biased here, as in every other way I love this TV, but I can't give a glowing review when I'm currently waiting for my TV to be repaired or replaced under warranty. If this process is quick and painless, and things are plain sailing from that point on, I may come back and update my review...

New tv
Unfortunately our new tv showed a bright green stripe down one side full screen then it stopped working completely after one hour of use. Very disappointed

Easy setup, good picture
[This review was collected as part of a promotion.] Great oled TV, working with Sky Q and older LG soundbar. Had a time sync issue on order of switch on where the soundbar would not select the hdmi in input when switched on. But remedied by plugging in SkyQ directly to TV so ARC is always used.

Very Complicated
Although this is a good TV we find it extremely complicated and are unable at this moment to play it through our sound system without the sound breaking up. We have played our previous TVs through it no problem. We are even considering returning it to John Lewis. All we want is to be able to switch on a TV and be able to access our Sky channels. As simple as that nothing else, no voice activation etc.
Georgie, Kent
Upgrade for picture quality and service options
[This review was collected as part of a promotion.] Upgraded so we have choice of Freesat, Freeview if we didn't want Virgin box or Sky box. Lovely picture, surprising sound quality. Responsive UI. No complaints so far.
