You'll find ideas like yours along with boards, connections and panels. The truth is that you won't know till you replace a few parts which one it is.
Hello people I came across this problem
That is this line in centre of tv is like 4 inch all the way down now its black and flashes with white stripes
But it's been other colours too.
Like 6 months ago it was only once in a while.
Then I stored tv and then I moved I set up my ty now it's almost permanent.
I'm disappointed no longer under warranty I ordered a t-con board don't even know if it will help but going to try it out if someone know what the problem is that would be awesome and much appreciated.
