Hi all, this is my first post. My iPad pro 2018 12.9 inch (model 1895) went black during usage outside at 28°C. Then I noticed that the actual display shows picture but the backlight is not illuminating any more. I have opened the iPad and checked the logic board for visual damage but everything seems to be OK. The filters next to the display connectors are also ok. Does someone has experienced this issue or has the schematic for my ipad? Would be very helpful
