Hi all, I've repaired a few 3DS consoles recently but come across another today that looks immaculate. No signs of drops, no water damage. Looks brand new on the outside and inside! Problem: When plugged in the charging light comes on then off a few seconds later. The power button gives no response at all, no blue light, nothing. I've I've swapped the mainboard with another mainboard and everything works flawlessly, so it's definitely the mainboard that's the issue. Also ruled out the wifi module and IR module, both working fine in another 3DS. Checked both fuses with a continuity test and both are working. Any ideas? Maybe the power button itself on the board is faulty, if so how could I rule this out? Thanks in advance! Edit: Lifted the SW1 power button and bridged the connection to see if it was the power button. Same issue. Doesn't seem to be the button.
