try the laser cable as if u didnt reconect it propaly then this will happen check both ends ie one going to the mobo and the other end at the laser if this is still happing get a good strong Magnifying glass and look over the points you soldered to as you might have a solder bridge if still no luck unstall the chip and all the solder you put on the mobo and see does it read normal games
hope this helps
