slim line v13, laser doesn't move but lights up

when the lid is closed, the laserhead doesn't move at all, but after a few seconds the red light comes up. i allready tried other lasers but with no luck.

i checked the resistors and fuses on the board but they seem to be allright. so i can't blame them.

i thought this could be the RS2004. does anyone know how to measure or something?

does anyone know what this else could be??

thanks in advance

 

nobody seems to care!
but never mind, i allready got the solution and i solved it.
the RS2004FS was fried somehow.

 

i removed a RS2004 from a dead board and placed it on the mobo. now it works like new again!!!
