I'm puzzled about the warranty, I was under the impression that you normally have 12 months, and I believe there is an EU ruling (cant find it right now) which states 24 months. Anyway I'd expect you to have a good case under the UK consumer protection legislation as the goods are obviously not fit for purpose, I dont think under the circumstances it matters that the goal posts are debatable as that should be sorted by the manufacturer when designing the TV.
