Dreamcast is the last console from Sega Corporation - once a big player in the home entartainment business. Since all of the official support ceased way back in 2002, it's hard (and expensive) to find spare parts for it. Unlike the more popular consoles, Sony Playstation for instance, whose power supply or new laser unit can be easily bought even today, there is no such possibility when it comes to Dreamcast. Therefore, it's worth knowing how to fix smaller or bigger problems all by yourself..
