No sledgehammer required ;>). It appears your backlight is not working. It could be the screen itself or the backlight circuit on the logic board. Did this problem occur out of the blue or was it following a drop or impact or perhaps a repair attempt? The first thing to try is a replacement screen, preferably a known-good or high quality. You can follow this guide to replace it yourself. If that doesn’t solve the problem then you have a logic board issue. The iPhone 6S backlight circuit tends to blow easily, especially when folks forget to disconnect the battery prior to removing or installing a the screen. Unfortunately, this would not be a DIY fix and you would need to find a micro-solderer to do the repair.
