Great price for a top TV


Bought this TV a couple of weeks ago because of a good price and 6 year guarantee. It was very easy to set up and didn't need very much tweaking. Sound is much better than my previous LG TV even without a sound bar.

Best 4K UHD TV for the price


Been living with a OLED LG tv in our lounge for a year which is brilliant. But needed a replace tv for the dinner room where I'm sent if I'm watching the footy. Did a lot of checks on reviews and on pricing and found this tv at Richer Sounds for best...

Great picture.


Bought this two weeks ago and it was so easy to set up. It's a great picture out of the box. Some adjustments needed for personal taste but really easy to do.

Amazing TV - just what we were looking for


I bought this TV 10 days ago and we're delighted with it so far. The picture quality is great and the sound is even better than expected. The TV is also really user friendly. A huge improvement on our old set.
