Hardware New Nintendo 3DS XL powers on then suddenly it goes off

[weks]

Hi guys, i'm in need of some help, yesterday i tried disassembling my 3ds to swap the damaged buttons with my other 3ds, i disassemble all off the botom part, except the black flex cable and cables to the upper screen.

After swapping the buttons i assemble all back together and i try turn it on. It powers on , the blue light is on, then it goes off. No Popping sound occurred. It just powers off, when i tried it again, its the same, powers on then off.

Do u guys know what went wrong here? thanks

reattach the black flex cable and cables to the top screen.
since you did not detach them before, they may have came loose when moving the board.

i'll try to reattach them thanks. i'll report back the result, i'm worried that it may be caused by the main board power flexcable. since it is hard to buy one .

EDIT: Thanks man it works !!
