I changed the screen on my wives iphone 6 plus. Routine procedure. New screen appeared to activate and light up fine. Then a blueish tint appeared over the batter icon and the screen became hot. I shut it off to dbl check connections and now it will not tirn on at all. Tried a new screen and that wont light up or work. Any help would be appreciated
To extend on Ben’s answer most likely shorted the one or both of the backlight circuits. In the iPhone 6 plus you have two circuits and many times voltage skips the filters and goes right to one or more of the backlight caps. Unfortunately this is becoming more common with aftermarket screens connected to i6 and i6 plus models. As Ben said it could be one more more of the filters but most likely (especially if phone is getting hot) you have shorted your backlight line. Basically you’ll need to get under the cpu shield and rebuild part or the entire backlight line….if this is what happened that is.
