I would be curious to know what the build date was of your TV, as there was an update/turn of the main board in the first few months after release (mine was replaced back in the Fall of 2015).
Swapped the T-CON board, no fix. I just replaced the mainboard and that did fix it. 🙂 So now I have spare T-CON board. Going to keep an eye out for another mainboard too, in the event I have to deal with this again. The build date of my TV was October 2015 by the way.
I don't know how I didn't stumble on this earlier. I'm having same problem after hitting the 2 year mark. This has been my only tech (for whatever reason) that I didn't get warranty on.
This April, right side of TV started to get fuzzy white vertical lines.
This June, a clear fuzzy line down middle of screen, left half perfect, right half was hit or miss.
End of June, right half of TV would alternate through neon overlays to whatever image color was primary on screen. At same TV, smart functions (like the menu) would no longer operate or pop up when button was pressed.
I swapped main board, TV power on to grayish screen, with no division or lines, but no smart menu or cable comes through HDMI.
Haven't been able to get my hands on tcon board.
I'm wondering if this is the issue?
I have a 55EF9500. 2015 model purchased in March 2016
