Hi guys an gals... I'm trying to fit a what I thought was a type b screen into a 40 pin GBA... the one with the even ribbon cable and the white tab... I've soldered the adaptor cable but the screen doesn't power on... I read that it would appear washed out but I get nothing... Is there a way to power the screen to test it's working without an sp? I purchased the screen from Ali express.... Does it have to be a brown tabbed screen to work with the 40 pin gba? Ta peeps!!
