So I got a 3DO from a guy and was told it was working. Well I get it home and try to eject the disc tray and it does and the logo comes up. Then it automatically closes and the screen goes black with no results. Now if I hold the tray open it will stay and it displays dash and the 3DO logo and seems to work fine. Then once I close the tray the access light lights up for like 1 second and the screen goes black again. Anyone got any ideas?
