Why does everything have a blue tint?

Hello all. In response to the “blue screen” problem, please read the answer given by - den@techfixed4u on 03/16/2019 - in the earlier posts above. My LG tv was purchased four and a half years ago, but following den’s advice, I went to Currys/PC World, from whom the tv was bought, stated my reason for requiring a repair, mentioning the Customer Rights Act (2015), and they agreed to repair it without any fuss or argument!

My TV from 2017 43 inch is starting to turn blue. You can tell slightly on white colours. And reading from this forum its a dead end chasing anyone for repairs. I guess I'll have to buy new TV when this one gets too annoying.

Problem solved. Brand new LED's. $175 labor and parts. Looks perfect again.
