Hardware Question about defect systems..

[Piorjade]

I already have a working o3ds (w/ AL9H) but I'm thinking of buying a n3ds...
So I looked online for the prices and saw a defect system. The seller says that it boots, but the screen doesn't turn on and there is no sound.

My question is would it be possible to fix this with a hardmod somehow (I don't know if it is a softbrick or hardbrick, thats why I'm not sure) ? Or do you guys think this is a hardbrick?

For people interested in the original description:
"defekt (DS schaltet sich ein, überträgt jedoch weder Bild noch Ton)"

Roughly translated:
"defect (DS boots but doesn't output anything (visual + sound))"

Nvm I think it's not possible without a NAND backup, which I wouldn't have when buying the system
