Hisense TV, 50"

We purchased this Hisense TV, 50" for our guest room as it was an extremely good price for a 50"; newer model. The quality is awful and flickers a lot; when scrolling to different channels and or movies it's terrible; the flickering when scrolling to find something to watch and watching a movie/tv show it is just awful. The sound is quite good but the picture quality is horrible!
