Good morning,
Just a quick blarb to show you where I'm at.
I have a Samsung (unfortunately curved) 55inch JS8500, that has had a few screen replacements in its history. (They had varying degrees of success)
I wasn't happy with the 5th and final one (so the insurance paid out and let me keep the TV.)
I had a box about 3/4 inchs around the screen and bad light bleed in the corners, that I have lessened. I have taken the back off , slackened the white plastic screws/ taken off the front bezel and taped the inner edge and it's softened the effect.
However I am still left with an outline box around the frame, it shows up on some blues and Grey's currently, before I fettled with the screen it was on all colours.
So what I'm asking then I guess, would the attached be the backlight channels that might need some blocking behind the panel or is this banding / retention?
