iPhone screen is black after replacing battery

The iPhone screen works, but the screen is black. The backlight is not working. When attaching the screen, you may have noticed a puff of smoke and smelled a burn odor.

To confirm that the backlight is no longer working, disconnect the battery, reconnect it, then plug in a USB lightning cable. Immediately shine a bright light on the center the screen and you should be able to see a faint apple logo. That will confirm that there is a problem. This can happen if the iPhone is not turned off or the battery is not disconnect before starting repair. With the iPhone 6s and the iPhone 6s Plus, the device still receives power when the phone is powered off so you have to disconnect the battery as well.

To resolve, you will need to replace the Backlight or the complete LCD.
