Switch oled not turning on after housing replacement

Hello! Would appreciate so much wisdom in this issue I did to myself haha 😅

I was replacing the backplate and bottom bar yesterday with extremerate shells and although I did everything carefully, may not had been careful enough as once almost closed, I tried to turn it on and didn't respond 😅 checked if everything was connected, the battery cable, the 5 ribbon cables and all as doesn't seems I forgot something to connect, tried connecting it to the dock to see if it was a display issue but it just blinks once the dock and turns off, tried turning on that way and nothing, left it charging overnight and pushing thr power button for 30 seconds and 30 seconds other combinations and nothing

What I did notice tho is that when I plug the battery its silent but once I hit the power button it starts to do a barely audible buzzing sound in the charging area which said sound isn't audible once everything closed

Tho one cable I admit might had bent too much is the fan one as some of you may know is kinda of a difficult place to put if not having the right tools ^^;

Any idea of what could be and things I could try to make it work again?
