I recently replaced power connectors on two DSi XLs. Both couldn’t charge, and one worked on the battery while the other didn’t. I replaced the connectors and a dead charging circuit fuse on one of them (only one dead fuse).
Now both are dead, and one only has an orange flashing light like the power fuse is burnt when plugged in, while the other is just … no life.
New Power connectors all beep out just fine for continuity. All fuses beep out just fine. All ribbon cables are seated.
What the hell did I do or fail to do? Any guesses? My soldering was accurate, no stray touches, etc. Just wondering if there’s a common other issue that I might have overlooked beyond power connector & fuse replacement.
OK. Always good to start with the low hanging fruit.
You said the connectors beep out. Have you confirmed that the positive and negative power traces beep when the connector is installed in the slot? More than once, I’ve had connectors that look like they were properly inserted, but actually weren’t.
If the length of the cable through the connector has continuity, try checking continuity all the way from the battery terminals to the mainboard.
If that also shows continuity, can you post hi-res photos of both sides of the boards, including your soldering work? It’s possible there’s other damage that you are missing but that I might catch.
