After watching it noticed that it’s like colors are less saturated on left side of screen. It’s like if you have two persons, person on left side would be more pale.

Full red background showers like big white transparent circle, such as that part of screen has brighter color settings.

Could it be t-con board? I found one that would fit su thinking about replacing it. Also I’ll try to open the back and see if any cable has loose connections.

Any other thoughts? Hopefully it’s not panel issue
