So I’ve recently gotten a new motherboard to replace the old one. now as far as I’ve checked everything works fine but the screens won’t turn on and no sounds comes out of the speakers. do I just not have the ribbon cables seated right?
I just had similar issue when rebuilding a DS lite and the WiFi board was not on securely, I would assume that could cause same thing on a 3ds. If ribbon cables weren’t in right it would turn off right away.
