Hello… so i had the problem of No backlight and no Image, but now after some trials, Backlight is Back but the Starting screen used to be black with white apple logo, now the screen is White with faint apple logo and it’s stuck, but the backlight is On, No response from the phone, it’s always on not sleeping..
I would try to get a replacement screen. It seems to me the screen you have is faulty. Once you replace the screen you shouldn’t have anymore backlight issues! iPhone 6 Plus Screen Replacement iPhone 6 Plus Screen
