Picked up this DS for repair tonight. Complaint? To summarize, "...my son tried jamming a game in and now the games won't stay in."
I was a kid once. Some might say I'm still a kid. I remember jamming things into places too. Don't they say, "If it doesn't go, jam it in!"? Kids seem to think so. :)
These days, the only things I seem to end up jamming are my fingers and toes, and my bread, strawberry or mixed berry please!
As it turns out, there is a pin or rod (red arrow) that belongs under the flat spring next to it. The green line indicates where that pin/rod belongs for properly latching onto the game cartridge. After lifting the spring up, sliding the rod over, then laying the spring back down, I pushed the cartridge in again. It stayed put! I pressed against the cartridge and it released and ejected. I pushed it back in and it stayed locked into place again. Problem solved!
After removing the screws, separating the two halves, and disconnecting one flex cable, the cartridge slot was exposed and examined. At first, the problem wasn't blatantly apparent. After all, this was a new problem for me, so I wasn't sure where to begin. While looking at it under a microscope, I noticed something wasn't working quite right as I pushed the cartridge into place (circled in red below).
(That's not a challenge, don't really try harder to break something) ;)
