i've got two PS2 consoles that are having problems.

the 1st one's mine, scph 55006, it's the fat version, just that it's white in color.

much like deadwiller, my ps2 cant play DVD games.
it plays Audio CD.
but unlike deadwiller, while he can play the original demo disc.
mine cant play original games as well.

i've brought it to a nearby shop. they said it's problem with the lense.
they say it'll cost more than 300 bucks to replace it.

1) Is it really the lense? or is it the chip? Am i gettin rip here?
2) If it is the lense, how much does it cost to replace it?

The second console belongs to my friend, his PS2, scph 30001, is having a problem with the IC.
Boot up, his ps2 loads the game halfway thru the intro Playstation2 screen and stucks.
Sometimes he boots, and it doesnt load at all.
wat's the problem here?

thanks in advance, guys..
