iPhone won't turn on after replacing antenna?

Recently I started having issues with my phone disconnecting from bluetooth and wifi. Even when connected to wifi the signal was very poor even in close range so I tried replacing the antenna, however when I plugged every component back in the display wouldn’t turn back on. I replaced the new antenna with the old one again and still display won’t turn on. I even connected a working display from another fully working iphone 6 and still won’t display anything. iTunes is able to recognize my device. I’ve even tried recovery mode but still nothing. Could anyone help me figure out what the issue might be? Thanks in advance

It’s very important to always disconnect the battery before disconnecting/reconnecting the screen assembly. The issue is that the LCD connector has pins that have high voltages (i.e. the backlight is ~20V) and ground in very close proximity. When you fumble around trying to line up the connector plug to the receptacle, you can short out the voltage rail and cause damage to the components in the backlight circuit. If you’re lucky, then only a backlight filter is damaged but other times, the entire circuit could be affected. Either way, this type of repair requires micro-soldering and isn’t really a DIY repair.

To test for this, plug your device into a charger or an iTunes enabled computer. Then shine a bright flashlight on the screen. If you can see a dim image, then the backlight circuit has been damaged. If you can’t see an image at all, then it may be the LCD circuit that is damaged.
