Well, crap components are easier to damage easily
I've seen katsukity saying elsewhere that his boards are hand assembled (which is bonkers IMO), so there's that...
Fixing it is a fairly simple procedure. I've had my own share of repairs to do ... shit breaks, I understand. I don't mean to badmouth him, I'm just tired of having his problems pushed onto me.
What all has to be done to fix it?
I'll find someone (other than him) to fix it-as I've gone to his shop at least six times between both New3DSs. That's a good $200 or so too much.
Of course, it's just a temporary fix until I eventually replace them with yours.
