Psone modchip stopped working

Hello everyone, I bought a Psone premodded and it played backups and out of region games just fine, I traveled and brought the psone with me and stayed for some months there, when I was at my destination it was working just fine.

On my trip back however, it stopped reading backups, it would recognize some as cd tracks, and my Japanese game was recognized as a Music disc with tracks on it, so I know the disc's are reading just fine (the drive was recently changed before I bought it BTW), when it booted just fine previously, I have no idea what happened, can anyone help me out?
Here are some images of my console: (IT'S NTSC U)

Thanks for the answer, the games failed to boot sometimes back then, so maybe cleaning it with isopropyl alcohol will help, will try it tomorrow.
The wires were my first doubt, so I checked and it seems to be all in place thankfully, but maybe I'm wrong.
