Need Gameboy Micro repair help
in Help Wanted!
I have two Gameboy Micros that have faults I've been working on for some time, and I'm looking for some help diagnosing and repairing since I've run out of ideas.
Micro 1: It had a knackered charging port, which I've replaced with one from a link cable. That went really well, but it's still not charging. I've replaced fuse F2, but it still doesn't light up when I plug the charger in. I *might* have overheated something when removing the charging port? No idea what, but that's my only guess right now. It turns on and works fine using a battery charged from elsewhere, so it's only the charging circuit that's affected.
Micro 2: Wouldn't power on. I jumped fuse F2 like a dumbass, which obviously did nothing. I recently replaced fuse F1, which was much more probable, but now when I power it on, smoke comes out. Yeah, I'm thinking this one has a short somewhere, but no idea where to start with this one. Cosmetically it's fine inside, so it hasn't been dunked in a glass of water or something like that. To recap, did nothing when powered on before, with fuses F1 and F2 replaced, it emits smoke from somewhere central. So I guess F1 was blown, but there's actually an underlying issue.
Any help appreciated, even if it's telling me to visit another forum!

I've checked my soldering on the port, and it looks very good, but your tip about a component sliding around is a great shout. I'll give it a look later!
Thanks. I fear for Micro 2 as well. It was only super brief, less than 1 second x 2. Any idea what the cause was? I don't want to give up yet if I can help it.

Probably a short somewhere on the board.
