Question Oled picture problem

[JoeSass1]

Hello I have a oled that's a few years old. I just noticed this blue haze line that's about 4 inches thick near the bottom of my screen. Any ideas

Hi JoeSass. From what I’ve read and watched videos in the past for this type of issue by, there can be a bad (loose) / broken connection along the outside edges to the screen in that area, or, a faulty “T-Con” board causing the issue. Hopefully someone else will chime in with some more specific ways to test to determine which is the source of the problem. Best of luck!
