Game goes blank

try cleaning the laser lens with a Q-tip and rubbing alcohol (not dripping).
gently place the q-tip on the laser lens and gently twirl it.
use the other end of q-tip to dry it, again twirl it.

or you can use a laser lens cleaner for video game systems from Best Buy, etc.

hope this helps :D
