QE55Q8FNA With strange picture problem

[Goatsss]

So basically I have an issue appeared out of the blue. There's a roughly 3inch vertical bright spot/line that's appeared near the bottom centre of the screen, but there's also a dark shadow behind it that goes all the way from top to bottom... 

Any ideas what sort of problem I'm looking at here would be appreciated.

Hi @Goatsss 

Are you able to take a photo that will pick this up that you can send to us?

Hope you can see that OK. The small bright spot under the 17 and the dark vertical shadow behind it.

A led in the ledstrip is defect. It has gotten very hot, now the deffuser has been damaged.

A new deffuser is needed, also change the led strip(s)
