Should I fix this or just buy a new one. Sony KD-49XF7596

Hey, I've had this sony tv for some years now and suddenly it started showing certain content with like a pixeled mosai. Only happens in what I think is full hd content, UHD channels work fine, streaming services in 4K work fine and hdmi sources look fine too. Is it worth the chase for repair at this point?
