Item: iPad Pro 12 inch Blown Backlight/Touch filter Repair Combo set, 5x touch filters, 10x backlight filters, plus BONUS 2 backlight diodes
If you're here, it means someone didn't disconnect the battery! Unlike most iPhones, the touch system in iPad Pro is powered by the battery voltage--so there WILL be live voltage for touch at the connector in addition to backlight. It doesn't take much to temporarily short this voltage to ground at the connector when plugging in a screen---and POP goes the filter.
If you have a backlight failure, OR a touch failure then you know that both systems may have been damaged. We recommend replacing the entire set of backlight and touch filters anytime there was a short to ground at the connector. This will save you from having to open the device again and risk the screen.
We also recommend taking a CLOSE look at the screen connector. Do not plug in a screen with any bent/smushed pins or you will be popping filters again!
