Slim PS2 , whats the scoop
 

I have worked on both the regular and slim PS2`s . The regular ones have
the usuall issues but these slim ones i can not figure out to well .
Every one i get wont spin the disk at all .
This one now does the same . Once during pushing around quickly on the
lid switch i saw the lens light and the disk gave a short nudge . All
the checking i do does no good .
All i can guess here is the lazer is bad that causes this model to do
that ?

HELP !
