Hardware 3DS motherboard dead?

[mingi]

I disassembled my New 3ds XL' lower parts only, then put it all together, tried to boot it up but it wouldn't respond at all (no backlight, no blue light but it would charge with amber light) even though I did not break anything on mb or damaged ribbon cables like that.
I have several other 3ds so I tried to swap that problematic motherboard to other working devices but it wouldn't work on any working 3ds. (but the first 3ds where I got that motherboard would work and boot with another motherboard)

My question is that my motherboard is not responding but I'm not so sure if it's really dead because I did not damage any cable or pins and it was working fine an hour ago, so is there any way to test if your motherboard is completely dead or still salvageable.

can you get a scan or high quality photos of the motherboard, to check if any components have been knocked off?

same , i dont know what to do

i replaced the top screen, and it would not power on after, im positive i didnt do anything to damage it, ive taken it apart 5 separete times to try and replace the same screen (faulty rplacement screens) every time i could get it to power on, except for today , i even transplanted the board in question to a functioning New 3ds xl and it still wouldnt boot, no blue light, no backlight, just the orange charging light, lights up (since its plugged in) i didnt attempt to place the functionig 3ds board on the device in question since i fear the screen replacement might have damaged something on the board, i dont want to end up with two dead systems.
