Hardware 3ds motherboard issues

[MaiconErick]

Hello,

I had to replace a few parts of my old 3ds, which I had for years
While doing this, a few bad things happened, like me breaking the flat cable of my top screen and messing up the connectors of my bottom screen.
I bought new of those and when I connected everything again, it doesn't boot, the red power led doesn't even light up with only the battery connected

Then, as a troubleshoot step, I disconnected absolutely everything from the motherboard and when I connect it to the power source, the red power led stays on for about 4 seconds then it turns off. It doesn't boot if I try to press the power button during that time.

My question is:
Is this a clear sign that the motherboard is dead or it doesn't turn on anyway if everything is not connected? I was expecting to at least see the leds confirming that it is working, and maybe see something when I connect the bottom screen.

your system will not boot unless you have everything connected

That is not true.
Some pieces can be omitted without stopping a 3DS from starting. Cameras for example aren't strictly needed. I didn't try but I believe gamecart and SD readers aren't strictly necessary.

Backlights and the speaker/3D cable must be present as well as the WiFi board on old type consoles.

going over exactly what you have to and don't have to connect isn't going to help the OP

Wow easy guys lol
I gave up on it actually, my sd card got corrupted on top of everything that was going on so I lost my data already... The only thing I cared about the most is my playtime but I have a backup of the PlayHistory.dat
A bit outdated but it will be hard to know if I messed some component like a screen or something else to try to get the motherboard running again and get an updated file from the nand.
And I've been wanting to buy a new 3ds anyway...
Thanks for the info

Yes it does. Knowing what can be omitted and what not is important when troubleshooting especially since it is also known that malfunctioning components (camera) can cause issues - while disconnecting them isn't a problem.

I just always try my best to help people. Since forum threads can be found years later it is better to provide as much information as possible rather than oversimplified things like "have to connect everything"

DS consoles are finicky and easy to damage. I only touch the inner parts when strictly needed. If you are brave and willing to lose another one you could simply install the motherboard into a known good console (a risk I wouldn't be willing to take after having successfully replaced two upper screens)


Good luck and have fun!

Sadly, braveness needs money hahaha
But thanks for the help :>
