Hello everyone,

First time posting.

So my tv's LED light is constantly flashing pink. The pink illumintates all of the bottom half of my tv screen. I went into settings then 'illumination LED' and turned it to 'off'. The problem then corrected itself. However, when I turn illumination LED to 'Auto brightness adjust' (a setting which I've had on now over a year) the problem starts reoccuring again. Does anyone have a solution? I have tried to attach a photograph below.
