Hacking DS slot not working, GBA slot works fine

[blightniak]

My DS slot is not working, GBA slot works fine, have tried a number of different games. All the games work fine in another DS.

Looking in the slot, it looks okay, no damage, no dirt.

Any suggestion how to fix.

It is usually a collapsed pin inside the slot, only way to know for sure is to open the ds and have a closer look

Yeah what kitty said, open it up and check if the pin is connecting properly or if there is any dirt on the inside.
