Anything and everything about retro and modern console repair.

If you've got a broken gaming console you are trying to fix, come here to talk about it. If you want to flex about a repair, post here. If you or your console's last lover did a non-destructive electronic mod to their console, or have a question about the options available or how to do it, you are welcome to post here.

If you suck at soldering, we still love you, but we might roast you.

If you did an extreme modification such as turning one of the few Nintendo Playstations into a Rubik's Cube, flex elsewhere. If you're trying to FIX a Nintendo Playstation that someone turned into a Rubik's Cube, post away!

Dead DSi XLs - Repair failure - Question (lemmy.world)

submitted 1 month ago by [email protected] to c/[email protected]

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.

Try reseating the Wi-Fi modules, see if that makes a difference.

Also, sometimes the battery gets loose over the years. Try wedging a small bit of paper in the end opposite the connector, to try and wedge it in place more snugly.

Let me know either of these things change anything.

I already tried the Wi-Fi reseating. One unit I bought, that was the only thing that was wrong with it. But not the two ones that I managed to kill more than they were already dead. The Wi-Fi boards are interchangeable between units, aren’t they?

I will try the battery again but I already hold the battery in place when I’m testing and I highly doubt it’s the issue given that the contacts were working fine prior to the failed repair. I also tried several batteries that I know work. Nothing worked

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.
