I have XT1143 players that have started showing a purple hue to the screen after being on for more than 8 hours. Power cycling the display doesn't solve it, and the display's menu isn't affected. When I republish a presentation, or power cycle the player things go back to ok for a few hours, then back to purple.
Tried 7.1.65 firmware, as well as downgrading back to 6.x firmware as well.
What else should I look for?
LG 55LV35A, 55SE3B and 49SE3B displays FYI
