I got a v3 (SCPH-30000) from a friend that complained it wouldnt read games. So I took it apart, and lo and behold, the KHS-400B laser hits the controller board under the rails. What kind of laser is supposed to be in it? The console isnt modded, so they couldnt have ran lenschanger, but I was under the assumption that 400B's came with the earlier versions? What would fit, or how can I make this one work?
