Chosen Solution
I changed motherboards and i have tried this one in 2 different consoles and it won’t boot up. If you connect the charger it will give the orange light 5s and it will turn off. If you turn it on it gives blue light 5s and then it turns off and does the pop sound. I checked all zif cables/connectors and exchanged batteries. The other motherboard works on both consoles.
Check your fuses, diodes; power circuitry. The fuses (in red) should have continuity, the diode (in blue) when tested with multimeter: red lead on output and black lead on input should be OL; reversing the leads should give 0.165V (Diode test mode). Also check the resistor values, and inspect the solder joints.
The fuse for the battery power is located on the action buttons board (in red).
You could also try refering to this post on GBA for additional help/info: GBATEMP Apparently replacing the daugtherboard fixed the issue in that case.
If you have the blue light and pop sound and you’ve checked and double-checked the ribbon cables and connectors then it’s likely that one of the ribbon cables has a tear in it at the hinge. It could also be a connection in the upper portion of the console. Hope this helps.
For the new generation, check the ziff connector to the back light of the lower lcd. These can get loose. Also check which displays flashes when the pop sound is heard. This can be an indicator on which cable is the problem. The older generation is usually the 3d cable that had the slight tear near the hinge
will this work for the first 3DS XL … I’ve replaced the port but need to check fuses
