Nintendo 2DS XL – Orange light, no blue light, signs of overheating

[Tomylee]

Hi everyone, I have a Nintendo 2DS XL that shows the orange charging light when plugged in, but nothing happens when I press the power button — no blue light, no screen, no sound.

Here's what I've observed:

All ribbon cables are properly connected

Battery is present and in good condition

No reaction even with screens disconnected

There's a visible burn mark / overheating sign on the metal shield, right above the CPU


I’m suspecting an issue with the CPU, PMIC, NAND, or a power line.
If anyone has experienced something similar or has suggestions for further testing, I’d really appreciate your help.

Thanks in advance!

No idea, but you could start by checking all the power rails to see if they are present and correct.

Hi, thanks a lot for your reply! 🙏
This is my first time playing around with a Nintendo 2DS XL, so I want to make sure I understand what I’m doing.

You mentioned checking the main power rails — would you be able to help me figure out exactly which ones I should be testing? If you have any info about their locations, test points, or the expected voltages, that would be super appreciated.

I’ve got the right equipment (multimeter, lab power supply, etc.), I just want to make sure I’m testing the right things in the right places.

Thanks in advance for your help!

The best way to know where the rails are is from a schematic and (hopefully) boardview, if you can even get them, I don't know.

The second way is to identify all the ICs on the board. There will be at least some voltage regulator and a charge controller chip.
When you identify these, you can look up the datasheets and figure out what is supposed to be going on, then start measuring to see if the readings are as expected or not.

It's possible that someone has already done such a thing, and posted the information elsewhere on the internet. So, research would be a good start.

I also see that these consoles may have some protective fuses on the board, it's possible one of these has failed.

Are you able to get some close up photos of the ICs so the numbers can be read properly? Also some general close ups to see if any fuses may be on the board.
