So I made the mistake of buying a used Nintendo 3DS on ebay. I played some 3DS games fine for a while then decided to try out some DS games.
However, everytime I try to load a DS game the system turns into a black screen, the 3D light fades out and the system is locked up completely. I have to hold down power for about 5 seconds then close the lid and reopen it and press power to turn the system back on again.
On the Home screen the DS game shows up properly. Also if I go into the system settings and look up the Activity Log for games, it shows that I played the DS game for the amount of the time the system was showing a black screen and locked up.
I've tried formatting the 3DS, updating the firmware to the latest version, disabling wifi, removing the SD card and trying other SD cards with no difference in results. I've also tried the same DS cartridges on a friend's 3DS and they load up perfectly fine on his.
I'd rather not send the system in for repairs. I'll be on travel for a couple months in a week and bought the system hoping to take it with me.
Anyone have any ideas for things to try?
