iPhone 6 coil replacement

First there was no backlight and only LCD worked. The backlight diode was totally burnt and coil was cracked a little on top. Also capacitor (C1505) was shorted. So I replaced all of them, diode, coil and that one capacitor.

And after replacement now the lcd also not working and no backlight. My first question is: when I installed new coil there wasn't that little dot on top of it (on that new one) so does it matter which way I install that coil?

Here is the video after failed repair: https://youtu.be/JnRK43eQD1U

Can anybody tell what is going on please?
